Direct Answer: Weight Specifications and Metric-to-Imperial Conversion<\/h2>\n\n    <p>The (N)TSFLCGEW\u00d6U 4&#215;185 0.6\/1kV heavy-duty festoon cable has a nominal weight of <strong>10,500 kg\/km (kilograms per kilometer)<\/strong>, which converts to <strong>7.06 lbs\/ft (pounds per foot)<\/strong> in imperial units.

Why Cable Weight Matters: The Physics of Festoon System Design<\/h2>\n\n    <p>To understand why cable weight is so critical to festoon system engineering, it helps to step back and think about what a festoon system actually does. A festoon system is a cable support and delivery mechanism that allows power, control signals, or both to be routed to a moving piece of equipment\u2014such as a container crane, overhead gantry, or mine hoist. The cable is not laid in a fixed conduit; instead, it is suspended from pulleys mounted on a trolley, which itself travels along a fixed rail or support structure. As the main equipment moves (say, a crane travels along a dock to position above a ship container), the festoon trolley rolls along its rail, and the cable coils and uncoils from the trolley&#8217;s support structure in a choreographed dance.<\/p>\n    <p class=\"cn\">\u8981\u7406\u89e3\u4e3a\u4ec0\u4e48\u7535\u7f06\u91cd\u91cf\u5bf9\u8f6f\u7ba1\u7cfb\u7edf\u5de5\u7a0b\u5982\u6b64\u5173\u952e\uff0c\u6709\u52a9\u4e8e\u9000\u4e00\u6b65\u601d\u8003\u8f6f\u7ba1\u7cfb\u7edf\u5b9e\u9645\u4e0a\u505a\u4ec0\u4e48\u3002\u8f6f\u7ba1\u7cfb\u7edf\u662f\u4e00\u79cd\u7535\u7f06\u652f\u6491\u548c\u8f93\u9001\u673a\u5236\uff0c\u5141\u8bb8\u7535\u529b\u3001\u63a7\u5236\u4fe1\u53f7\u6216\u4e24\u8005\u8def\u7531\u5230\u79fb\u52a8\u7684\u8bbe\u5907\u2014\u2014\u4f8b\u5982\u96c6\u88c5\u7bb1\u8d77\u91cd\u673a\u3001\u5f00\u9500\u95e8\u5f0f\u8d77\u91cd\u673a\u6216\u77ff\u4e95\u63d0\u5347\u673a\u3002\u7535\u7f06\u4e0d\u662f\u94fa\u5728\u56fa\u5b9a\u7684\u5bfc\u7ba1\u4e2d\uff1b\u76f8\u53cd\uff0c\u5b83\u4ece\u5b89\u88c5\u5728\u6ed1\u8f6e\u8f66\u4e0a\u7684\u6ed1\u8f6e\u60ac\u6302\uff0c\u6ed1\u8f6e\u8f66\u672c\u8eab\u6cbf\u7740\u56fa\u5b9a\u7684\u5bfc\u8f68\u6216\u652f\u6491\u7ed3\u6784\u79fb\u52a8\u3002\u5f53\u4e3b\u8981\u8bbe\u5907\u79fb\u52a8\uff08\u6bd4\u5982\uff0c\u8d77\u91cd\u673a\u6cbf\u7740\u7801\u5934\u79fb\u52a8\u4ee5\u5b9a\u4f4d\u5728\u8239\u8236\u96c6\u88c5\u7bb1\u4e0a\u65b9\uff09\u65f6\uff0c\u8f6f\u7ba1\u6ed1\u8f6e\u8f66\u6cbf\u7740\u5176\u5bfc\u8f68\u6eda\u52a8\uff0c\u7535\u7f06\u4ee5\u7f16\u6392\u7684\u821e\u8e48\u4ece\u6ed1\u8f6e\u8f66\u7684\u652f\u6491\u7ed3\u6784\u4e2d\u5377\u548c\u5c55\u5f00\u3002<\/p>\n\n    <p>The physics of this motion introduces several weight-related challenges. First, the cable hanging between the trolley&#8217;s coil point and the moving equipment represents a distributed load that must be supported by the trolley wheels and the suspension mechanism. For a 300-meter cable run weighing 3,150 kg, this hanging mass creates enormous mechanical stress. If the cable is not supported at frequent enough intervals, excessive sag develops, the cable may catch on obstacles, and the mechanical stress concentrates at a few points, accelerating fatigue failure. If support points are too closely spaced, unnecessary friction develops as the cable rubs against support members.<\/p>\n    <p class=\"cn\">\u8fd9\u4e2a\u8fd0\u52a8\u7684\u7269\u7406\u5f15\u5165\u4e86\u51e0\u4e2a\u4e0e\u91cd\u91cf\u76f8\u5173\u7684\u6311\u6218\u3002\u9996\u5148\uff0c\u60ac\u6302\u5728\u6ed1\u8f6e\u8f66\u5377\u70b9\u548c\u79fb\u52a8\u8bbe\u5907\u4e4b\u95f4\u7684\u7535\u7f06\u4ee3\u8868\u5fc5\u987b\u7531\u6ed1\u8f6e\u8f66\u8f6e\u548c\u60ac\u6302\u673a\u5236\u652f\u6301\u7684\u5206\u5e03\u5f0f\u8d1f\u8f7d\u3002\u5bf9\u4e8e\u91cd\u8fbe 3,150 \u5343\u514b\u7684 300 \u7c73\u7535\u7f06\u8def\u7ebf\uff0c\u8fd9\u4e2a\u60ac\u6302\u7684\u8d28\u91cf\u4ea7\u751f\u5de8\u5927\u7684\u673a\u68b0\u5e94\u529b\u3002\u5982\u679c\u7535\u7f06\u7684\u652f\u6491\u95f4\u9694\u4e0d\u8db3\uff0c\u4f1a\u53d1\u751f\u8fc7\u5ea6\u4e0b\u5782\uff0c\u7535\u7f06\u53ef\u80fd\u4f1a\u5361\u5728\u969c\u788d\u7269\u4e0a\uff0c\u673a\u68b0\u5e94\u529b\u96c6\u4e2d\u5728\u5c11\u6570\u51e0\u70b9\uff0c\u52a0\u901f\u75b2\u52b3\u5931\u6548\u3002\u5982\u679c\u652f\u6491\u70b9\u95f4\u9694\u592a\u7d27\uff0c\u5f53\u7535\u7f06\u4e0e\u652f\u6491\u6784\u4ef6\u6469\u64e6\u65f6\u4f1a\u4ea7\u751f\u4e0d\u5fc5\u8981\u7684\u6469\u64e6\u3002<\/p>\n\n    <p>Second, the cable weight directly influences the system&#8217;s acceleration and deceleration characteristics.

Why? Manufacturing tolerance is the primary reason. When rubber is extruded onto a cable, the temperature, pressure, and line speed all influence how much material adheres to the conductor. A hotter extrusion stream deposits more material; a cooler one, less. Additionally, the density of the rubber compound itself can vary slightly between batches\u2014different raw material sources, ambient humidity during mixing, or aging time of the compound can all affect the final density. VDE 0250-809 permits a weight tolerance of \u00b15% to \u00b18% for cables in the 4&#215;185 size range. This means an individual spool might weigh anywhere from 9,900 to 11,100 kg\/km and still conform to standard. For critical system designs where weight is a precise design input, always request certified weight data from the cable manufacturer and perform acceptance testing on delivered cable.<\/p>\n      <p class=\"cn\">\u89c4\u8303\u8868\u663e\u793a\u5178\u578b\u503c\uff0c\u4f46\u5b9e\u9645\u7535\u7f06\u91cd\u91cf\u53ef\u80fd\u4f1a\u6709\u6240\u4e0d\u540c\u3002\u4e3a\u4ec0\u4e48\uff1f\u5236\u9020\u516c\u5dee\u662f\u4e3b\u8981\u539f\u56e0\u3002\u5f53\u6a61\u80f6\u88ab\u6324\u51fa\u5230\u7535\u7f06\u4e0a\u65f6\uff0c\u6e29\u5ea6\u3001\u538b\u529b\u548c\u7ebf\u901f\u5ea6\u90fd\u5f71\u54cd\u7c98\u9644\u5230\u5bfc\u4f53\u4e0a\u7684\u6750\u6599\u6709\u591a\u5c11\u3002\u8f83\u70ed\u7684\u6324\u51fa\u6d41\u6c89\u79ef\u66f4\u591a\u6750\u6599\uff1b\u8f83\u51b7\u7684\u5219\u66f4\u5c11\u3002\u6b64\u5916\uff0c\u6a61\u80f6\u6df7\u5408\u7269\u672c\u8eab\u7684\u5bc6\u5ea6\u5728\u6279\u6b21\u4e4b\u95f4\u53ef\u80fd\u7565\u6709\u4e0d\u540c\u2014\u2014\u4e0d\u540c\u7684\u539f\u59cb\u6750\u6599\u6765\u6e90\u3001\u6df7\u5408\u671f\u95f4\u7684\u73af\u5883\u6e7f\u5ea6\u6216\u6df7\u5408\u7269\u7684\u8001\u5316\u65f6\u95f4\u90fd\u53ef\u80fd\u5f71\u54cd\u6700\u7ec8\u5bc6\u5ea6\u3002VDE 0250-809 \u5141\u8bb8 4&#215;185 \u5c3a\u5bf8\u8303\u56f4\u5185\u7684\u7535\u7f06\u91cd\u91cf\u516c\u5dee\u4e3a \u00b15% \u81f3 \u00b18%\u3002\u8fd9\u610f\u5473\u7740\u5355\u4e2a\u7ebf\u8f74\u7684\u91cd\u91cf\u53ef\u80fd\u5728 9,900 \u81f3 11,100 \u5343\u514b\/\u5343\u7c73\u4e4b\u95f4\uff0c\u4ecd\u7136\u7b26\u5408\u6807\u51c6\u3002\u5bf9\u4e8e\u91cd\u91cf\u662f\u7cbe\u786e\u8bbe\u8ba1\u8f93\u5165\u7684\u5173\u952e\u7cfb\u7edf\u8bbe\u8ba1\uff0c\u59cb\u7ec8\u4ece\u7535\u7f06\u5236\u9020\u5546\u8bf7\u6c42\u8ba4\u8bc1\u7684\u91cd\u91cf\u6570\u636e\uff0c\u5e76\u5bf9\u4ea4\u4ed8\u7684\u7535\u7f06\u8fdb\u884c\u9a8c\u6536\u6d4b\u8bd5\u3002<\/p>\n    <\/div>\n\n\n    <!-- S4 -->\n    <h2 id=\"s4\">4. Understanding Conductor Cross-Section: 4&#215;185 mm\u00b2 and AWG Equivalency<\/h2>\n\n    <p>The designation &#8220;4&#215;185&#8221; refers to a cable with four individual conductors, each with a cross-sectional area of 185 square millimeters. To understand what this means in practical terms, it helps to compare this to the American Wire Gauge (AWG) system, which is still widely used in North America for cable specifications. A conductor of 185 mm\u00b2 is approximately equivalent to 350 MCM (thousand circular mils), which falls between the standard AWG sizes of 300 MCM and 400 MCM. (The exact equivalency is 185 mm\u00b2 = 357.8 MCM, close enough to 350 MCM for practical purposes.) This is an enormous conductor\u2014far larger than the household electrical wiring you might see in residential applications, which is typically 10 AWG (5.26 mm\u00b2) or smaller.<\/p>\n    <p class=\"cn\">&#8220;4&#215;185&#8243;\u7684\u540d\u79f0\u6307\u7684\u662f\u6709\u56db\u4e2a\u5355\u72ec\u5bfc\u4f53\u7684\u7535\u7f06\uff0c\u6bcf\u4e2a\u5bfc\u4f53\u7684\u6a2a\u622a\u9762\u79ef\u4e3a 185 \u5e73\u65b9\u6beb\u7c73\u3002\u8981\u4ece\u5b9e\u9645\u610f\u4e49\u4e0a\u7406\u89e3\u8fd9\u610f\u5473\u7740\u4ec0\u4e48\uff0c\u6709\u52a9\u4e8e\u4e0e\u7f8e\u56fd\u7ebf\u89c4\uff08AWG\uff09\u7cfb\u7edf\u76f8\u6bd4\u8f83\uff0c\u8be5\u7cfb\u7edf\u5728\u5317\u7f8e\u4ecd\u5e7f\u6cdb\u7528\u4e8e\u7535\u7f06\u89c4\u8303\u3002185 mm\u00b2 \u7684\u5bfc\u4f53\u5927\u7ea6\u76f8\u5f53\u4e8e 350 MCM\uff08\u5343\u5706\u5f62\u5bc6\u8033\uff09\uff0c\u4ecb\u4e8e 300 MCM \u548c 400 MCM \u7684\u6807\u51c6 AWG \u5c3a\u5bf8\u4e4b\u95f4\u3002\uff08\u786e\u5207\u7684\u7b49\u6548\u6027\u662f 185 mm\u00b2 = 357.8 MCM\uff0c\u5bf9\u4e8e\u5b9e\u9645\u76ee\u7684\u8db3\u591f\u63a5\u8fd1 350 MCM\u3002\uff09\u8fd9\u662f\u4e00\u4e2a\u5de8\u5927\u7684\u5bfc\u4f53\u2014\u2014\u8fdc\u5927\u4e8e\u60a8\u5728\u4f4f\u5b85\u5e94\u7528\u4e2d\u53ef\u80fd\u770b\u5230\u7684\u5bb6\u5ead\u7535\u529b\u5e03\u7ebf\uff0c\u901a\u5e38\u4e3a 10 AWG\uff085.26 mm\u00b2\uff09\u6216\u66f4\u5c0f\u3002<\/p>\n\n    <p>So why is the (N)TSFLCGEW\u00d6U 4&#215;185 so large? The answer lies in the application. A container crane at a major port might need to deliver 461 amperes of electrical power to its hoist motor, and the power losses in the cable are proportional to I\u00b2R (current squared times resistance). With a large conductor like 185 mm\u00b2, the resistance per kilometer is very low\u2014approximately 0.025 ohms\/km for copper at 20\u00b0C. This low resistance means that even when carrying 461 amperes, the voltage drop across a 300-meter cable run is only about 3.5 volts, which is negligible for a 1000-volt system. If a much smaller conductor were used (say, 50 mm\u00b2 instead of 185 mm\u00b2), the voltage drop would become unacceptable, causing the motor to run at reduced torque and potentially leading to system faults.<\/p>\n    <p class=\"cn\">\u90a3\u4e48\u4e3a\u4ec0\u4e48 (N)TSFLCGEW\u00d6U 4&#215;185 \u5982\u6b64\u4e4b\u5927\u5462\uff1f\u7b54\u6848\u5728\u4e8e\u5e94\u7528\u3002\u4e00\u4e2a\u4e3b\u8981\u6e2f\u53e3\u7684\u96c6\u88c5\u7bb1\u8d77\u91cd\u673a\u53ef\u80fd\u9700\u8981\u5411\u5176\u63d0\u5347\u7535\u52a8\u673a\u8f93\u9001 461 \u5b89\u57f9\u7684\u7535\u529b\uff0c\u7535\u7f06\u4e2d\u7684\u7535\u529b\u635f\u8017\u4e0e I\u00b2R\uff08\u7535\u6d41\u5e73\u65b9\u4e58\u4ee5\u7535\u963b\uff09\u6210\u6b63\u6bd4\u3002\u5bf9\u4e8e\u50cf 185 mm\u00b2 \u8fd9\u6837\u5927\u7684\u5bfc\u4f53\uff0c\u6bcf\u516c\u91cc\u7684\u7535\u963b\u975e\u5e38\u4f4e\u2014\u2014\u5728 20\u00b0C \u65f6\u5bf9\u4e8e\u94dc\u7ea6\u4e3a 0.025 \u6b27\/\u5343\u7c73\u3002\u8fd9\u4e2a\u4f4e\u7535\u963b\u610f\u5473\u7740\uff0c\u5373\u4f7f\u627f\u8f7d 461 \u5b89\u57f9\uff0c\u901a\u8fc7 300 \u7c73\u7535\u7f06\u8def\u7ebf\u7684\u538b\u964d\u4ec5\u7ea6 3.5 \u4f0f\uff0c\u5bf9\u4e8e 1000 \u4f0f\u7cfb\u7edf\u6765\u8bf4\u662f\u53ef\u5ffd\u7565\u7684\u3002\u5982\u679c\u4f7f\u7528\u4e86\u5c0f\u5f97\u591a\u7684\u5bfc\u4f53\uff08\u6bd4\u5982 50 mm\u00b2 \u800c\u4e0d\u662f 185 mm\u00b2\uff09\uff0c\u538b\u964d\u5c06\u53d8\u5f97\u4e0d\u53ef\u63a5\u53d7\uff0c\u5bfc\u81f4\u7535\u52a8\u673a\u4ee5\u51cf\u5c11\u7684\u626d\u77e9\u8fd0\u884c\uff0c\u53ef\u80fd\u5bfc\u81f4\u7cfb\u7edf\u6545\u969c\u3002<\/p>\n\n    <h3>4.1 Why Class 5 Stranding for Heavy Duty Service<\/h3>\n\n    <p>The 185 mm\u00b2 conductors in the (N)TSFLCGEW\u00d6U cable are specified as Class 5 stranding per IEC 60228. Class 5 means the conductor consists of many fine copper strands (for a 185 mm\u00b2 Class 5 conductor, approximately 476 strands, each about 0.63 mm diameter) twisted together in a helical pattern. This approach provides excellent flexibility compared to solid conductors or coarser stranding, which is essential for a cable that will be repeatedly bent around pulleys in a festoon system. The fine stranding distributes bending stress evenly across all strands, preventing the stress concentration failures that would occur in coarser conductors. Over millions of flexing cycles, the Class 5 stranding ensures the cable&#8217;s conductivity remains stable and the insulation around each strand remains intact.<\/p>\n    <p class=\"cn\">(N)TSFLCGEW\u00d6U \u7535\u7f06\u4e2d\u7684 185 mm\u00b2 \u5bfc\u4f53\u6839\u636e IEC 60228 \u6307\u5b9a\u4e3a\u7b2c 5 \u7c7b\u7ede\u5408\u3002\u7b2c 5 \u7c7b\u610f\u5473\u7740\u5bfc\u4f53\u7531\u8bb8\u591a\u7ec6\u94dc\u80a1\uff08\u5bf9\u4e8e 185 mm\u00b2 \u7b2c 5 \u7c7b\u5bfc\u4f53\uff0c\u5927\u7ea6 476 \u6839\u80a1\uff0c\u6bcf\u4e2a\u7ea6 0.63 \u6beb\u7c73\u76f4\u5f84\uff09\u4ee5\u87ba\u65cb\u56fe\u6848\u626d\u5408\u5728\u4e00\u8d77\u7ec4\u6210\u3002\u4e0e\u56fa\u4f53\u5bfc\u4f53\u6216\u8f83\u7c97\u7684\u7ede\u5408\u76f8\u6bd4\uff0c\u8fd9\u79cd\u65b9\u6cd5\u63d0\u4f9b\u4e86\u51fa\u8272\u7684\u7075\u6d3b\u6027\uff0c\u8fd9\u5bf9\u4e8e\u5c06\u5728\u8f6f\u7ba1\u7cfb\u7edf\u4e2d\u7684\u6ed1\u8f6e\u5468\u56f4\u91cd\u590d\u5f2f\u66f2\u7684\u7535\u7f06\u81f3\u5173\u91cd\u8981\u3002\u7ec6\u7ede\u5408\u5747\u5300\u5206\u5e03\u6240\u6709\u80a1\u7684\u5f2f\u66f2\u5e94\u529b\uff0c\u9632\u6b62\u5728\u8f83\u7c97\u7684\u5bfc\u4f53\u4e2d\u4f1a\u51fa\u73b0\u7684\u5e94\u529b\u96c6\u4e2d\u5931\u6548\u3002\u5728\u6570\u767e\u4e07\u4e2a\u5f2f\u66f2\u5faa\u73af\u4e2d\uff0c\u7b2c 5 \u7c7b\u7ede\u5408\u786e\u4fdd\u7535\u7f06\u7684\u5bfc\u7535\u6027\u4fdd\u6301\u7a33\u5b9a\uff0c\u56f4\u7ed5\u6bcf\u6839\u80a1\u7684\u7edd\u7f18\u4fdd\u6301\u5b8c\u6574\u3002<\/p>\n\n\n    <!-- S5 -->\n    <h2 id=\"s5\">5.

Ethylene Propylene Rubber has thermal and electrical properties ideally suited to the 0.6\/1 kV voltage class. It resists partial discharge within the insulation (the ionization of tiny voids that can eventually puncture the insulation), maintaining high dielectric strength even after years of continuous operation. Its mechanical properties\u2014elasticity and tear resistance\u2014remain stable across the operating temperature range (-25\u00b0C to +80\u00b0C for flex use), preventing the brittleness that would develop in inferior materials exposed to temperature extremes. The nominal insulation thickness on each of the four conductors is approximately 3.0 to 3.5 millimeters, thick enough to provide robust protection against mechanical damage yet not so thick that it adds excessive weight or sacrifices flexibility.<\/p>\n    <p class=\"cn\">\u4e3a\u4ec0\u4e48\u4f7f\u7528 EPR \u7edd\u7f18\uff1f\u4e59\u70ef\u4e19\u70ef\u6a61\u80f6\u5177\u6709\u7406\u60f3\u9002\u5408 0.6\/1 kV \u7535\u538b\u7b49\u7ea7\u7684\u70ed\u548c\u7535\u6c14\u7279\u6027\u3002\u5b83\u62b5\u6297\u7edd\u7f18\u5185\u7684\u5c40\u90e8\u653e\u7535\uff08\u53ef\u80fd\u6700\u7ec8\u7a7f\u900f\u7edd\u7f18\u7684\u5fae\u5c0f\u7a7a\u9699\u7684\u7535\u79bb\uff09\uff0c\u5373\u4f7f\u5728\u591a\u5e74\u8fde\u7eed\u8fd0\u884c\u540e\u4e5f\u4fdd\u6301\u9ad8\u4ecb\u7535\u5f3a\u5ea6\u3002\u5176\u673a\u68b0\u7279\u6027\u2014\u2014\u5f39\u6027\u548c\u6495\u88c2\u62b5\u6297\u2014\u2014\u5728\u8fd0\u884c\u6e29\u5ea6\u8303\u56f4\u5185\u4fdd\u6301\u7a33\u5b9a\uff08\u67d4\u6027\u4f7f\u7528\u4e3a -25\u00b0C \u81f3 +80\u00b0C\uff09\uff0c\u9632\u6b62\u66b4\u9732\u4e8e\u6e29\u5ea6\u6781\u7aef\u7684\u52a3\u8d28\u6750\u6599\u4e2d\u4f1a\u51fa\u73b0\u7684\u8106\u6027\u3002\u56db\u4e2a\u5bfc\u4f53\u4e2d\u6bcf\u4e2a\u7684\u6807\u79f0\u7edd\u7f18\u539a\u5ea6\u7ea6\u4e3a 3.0 \u81f3 3.5 \u6beb\u7c73\uff0c\u539a\u5ea6\u8db3\u4ee5\u63d0\u4f9b\u5bf9\u673a\u68b0\u635f\u4f24\u7684\u5f3a\u5927\u4fdd\u62a4\uff0c\u4f46\u4e0d\u4f1a\u90a3\u4e48\u539a\u4ee5\u81f3\u4e8e\u589e\u52a0\u8fc7\u5ea6\u7684\u91cd\u91cf\u6216\u727a\u7272\u7075\u6d3b\u6027\u3002<\/p>\n\n    <p>The outer sheath, typically 4.0 to 5.0 millimeters thick, serves multiple purposes.

This roughly 2:1 ratio of copper to insulation\/sheath is typical for large conductors in the 150\u2013250 mm\u00b2 range and reflects the fundamental economics of high-ampacity cable design: larger conductors carry more current with less voltage drop, but they also require proportionally larger insulation and sheath layers to accommodate the larger conductor diameter and to provide equivalent mechanical protection.<\/p>\n    <p class=\"cn\">\u5bf9\u4e8e (N)TSFLCGEW\u00d6U 4&#215;185\uff0c\u5206\u89e3\u5982\u4e0b\u3002\u94dc\u542b\u91cf\u4e3a 7,104 \u5343\u514b\/\u5343\u7c73\uff0c\u4ee3\u8868\u603b\u7535\u7f06\u91cd\u91cf\u7684\u7ea6 67.7%\u3002\u7edd\u7f18\u548c\u62a4\u5957\u6750\u6599\uff08EPR \u7edd\u7f18\u52a0\u6c2f\u4e01\u6a61\u80f6\u62a4\u5957\uff0c\u5305\u62ec\u4efb\u4f55\u5185\u90e8\u589e\u5f3a\uff09\u6784\u6210\u5269\u4f59\u7684 3,396 \u5343\u514b\/\u5343\u7c73\uff0c\u6216\u7ea6 32.3% \u7684\u603b\u91cd\u91cf\u3002\u8fd9\u79cd\u5927\u7ea6 2:1 \u7684\u94dc\u4e0e\u7edd\u7f18\/\u62a4\u5957\u6bd4\u4f8b\u5bf9\u4e8e 150\u2013250 mm\u00b2 \u8303\u56f4\u5185\u7684\u5927\u5bfc\u4f53\u662f\u5178\u578b\u7684\uff0c\u53cd\u6620\u4e86\u9ad8\u8f7d\u6d41\u91cf\u7535\u7f06\u8bbe\u8ba1\u7684\u57fa\u672c\u7ecf\u6d4e\u5b66\uff1a\u66f4\u5927\u7684\u5bfc\u4f53\u4ee5\u8f83\u5c0f\u7684\u538b\u964d\u627f\u8f7d\u66f4\u591a\u7535\u6d41\uff0c\u4f46\u5b83\u4eec\u4e5f\u9700\u8981\u6309\u6bd4\u4f8b\u66f4\u5927\u7684\u7edd\u7f18\u548c\u62a4\u5957\u5c42\uff0c\u4ee5\u9002\u5e94\u66f4\u5927\u7684\u5bfc\u4f53\u76f4\u5f84\u5e76\u63d0\u4f9b\u7b49\u6548\u7684\u673a\u68b0\u4fdd\u62a4\u3002<\/p>\n\n    <p>For cost estimation, this information proves invaluable.

In mechanical engineering practice, a typical safety factor for cable support systems is 3\u20135, meaning the structure must be designed to safely support 3 to 5 times the maximum calculated load. For the port container crane example with 4,200 kg cable weight, a safety factor of 4 would require the structure to be designed to safely support 4 \u00d7 4,200 kg = 16,800 kg. This substantial factor accounts for the accelerations and shock loads that occur during high-speed crane operation, for potential loss of strength in structural members over decades of use, and for the inevitable dynamic amplification that occurs when moving equipment suddenly reverses direction or stops. Never design a festoon system using only the static cable weight without applying an appropriate safety factor.<\/p>\n      <p class=\"cn\">\u5728\u6240\u6709\u8fd9\u4e9b\u573a\u666f\u4e2d\uff0c\u7ed3\u6784\u8bbe\u8ba1\u5fc5\u987b\u5305\u62ec\u8003\u8651\u52a8\u6001\u8d1f\u8f7d\u3001\u77ac\u6001\u51b2\u51fb\u548c\u7cfb\u7edf\u4f7f\u7528\u5bff\u547d\u5185\u6f5c\u5728\u7535\u7f06\u964d\u89e3\u7684\u5b89\u5168\u7cfb\u6570\u3002\u5728\u673a\u68b0\u5de5\u7a0b\u5b9e\u8df5\u4e2d\uff0c\u7535\u7f06\u652f\u6491\u7cfb\u7edf\u7684\u5178\u578b\u5b89\u5168\u7cfb\u6570\u662f 3\u20135\uff0c\u8fd9\u610f\u5473\u7740\u7ed3\u6784\u5fc5\u987b\u8bbe\u8ba1\u4e3a\u5b89\u5168\u5730\u652f\u6301\u6700\u5927\u8ba1\u7b97\u8d1f\u8f7d\u7684 3 \u81f3 5 \u500d\u3002\u5bf9\u4e8e\u6e2f\u53e3\u96c6\u88c5\u7bb1\u8d77\u91cd\u673a\u793a\u4f8b\uff0c4,200 \u5343\u514b\u7684\u7535\u7f06\u91cd\u91cf\uff0c4 \u7684\u5b89\u5168\u7cfb\u6570\u9700\u8981\u5c06\u7ed3\u6784\u8bbe\u8ba1\u4e3a\u5b89\u5168\u5730\u652f\u6301 4 \u00d7 4,200 \u5343\u514b = 16,800 \u5343\u514b\u3002\u8fd9\u4e2a\u5b9e\u8d28\u6027\u7684\u7cfb\u6570\u8003\u8651\u4e86\u5728\u9ad8\u901f\u8d77\u91cd\u673a\u8fd0\u884c\u671f\u95f4\u53d1\u751f\u7684\u52a0\u901f\u5ea6\u548c\u51b2\u51fb\u8d1f\u8377\u3001\u7ed3\u6784\u6784\u4ef6\u5728\u6570\u5341\u5e74\u4f7f\u7528\u4e2d\u6f5c\u5728\u7684\u5f3a\u5ea6\u635f\u5931\uff0c\u4ee5\u53ca\u5f53\u79fb\u52a8\u8bbe\u5907\u7a81\u7136\u53cd\u5411\u6216\u505c\u6b62\u65f6\u4e0d\u53ef\u907f\u514d\u5730\u53d1\u751f\u7684\u52a8\u6001\u653e\u5927\u3002\u6c38\u8fdc\u4e0d\u8981\u4ec5\u4f7f\u7528\u9759\u6001\u7535\u7f06\u91cd\u91cf\u800c\u4e0d\u5e94\u7528\u9002\u5f53\u7684\u5b89\u5168\u7cfb\u6570\u6765\u8bbe\u8ba1\u8f6f\u7ba1\u7cfb\u7edf\u3002<\/p>\n    <\/div>\n\n\n    <!-- S8 -->\n    <h2 id=\"s8\">8.

For a (N)TSFLCGEW\u00d6U 4&#215;185 cable with linear weight of 10.5 kg\/m, if support points are spaced 2.5 meters apart, the midspan sag can be calculated using the catenary equation (the equation describing the natural curve of a hanging cable under its own weight). For a rough approximation, sag \u2248 (w \u00d7 L\u00b2) \/ (8 \u00d7 T), where w is the linear weight (kg\/m), L is the span (m), and T is the tension in the cable. For our case with w = 10.5 kg\/m, L = 2.5 m, and assuming a reasonable tension T of 500 N (about 50 kg-force), the sag works out to approximately 80 mm (3.1 inches). This is within the acceptable 1\u20132% range (2.5 m span \u00d7 1\u20132% = 25\u201350 mm sag), though on the generous side. A designer might reduce spacing to 2.0 meters to reduce sag to more conservative 50\u201360 mm, or increase tension in the support cable system to reduce sag without changing physical spacing.<\/p>\n    <p class=\"cn\">\u884c\u4e1a\u4e2d\u5e38\u7528\u7684\u7ecf\u9a8c\u6cd5\u5219\u662f\uff0c\u6700\u5927\u4e0b\u5782\uff08\u7535\u7f06\u5728\u4e24\u4e2a\u652f\u6491\u70b9\u4e4b\u95f4\u4e2d\u70b9\u5904\u7684\u5782\u76f4\u4e0b\u964d\uff09\u4e0d\u5e94\u8d85\u8fc7\u652f\u6491\u70b9\u4e4b\u95f4\u8de8\u5ea6\u957f\u5ea6\u7684 1\u20132%\u3002\u5bf9\u4e8e\u7ebf\u6027\u91cd\u91cf\u4e3a 10.5 \u5343\u514b\/\u7c73\u7684 (N)TSFLCGEW\u00d6U 4&#215;185 \u7535\u7f06\uff0c\u5982\u679c\u652f\u6491\u70b9\u95f4\u9694 2.5 \u7c73\uff0c\u53ef\u4ee5\u4f7f\u7528\u60ac\u94fe\u7ebf\u65b9\u7a0b\u8ba1\u7b97\u4e2d\u8de8\u4e0b\u5782\uff08\u63cf\u8ff0\u5728\u81ea\u8eab\u91cd\u91cf\u4e0b\u60ac\u6302\u7535\u7f06\u7684\u81ea\u7136\u66f2\u7ebf\u7684\u65b9\u7a0b\uff09\u3002\u5bf9\u4e8e\u7c97\u7565\u8fd1\u4f3c\uff0c\u4e0b\u5782 \u2248 (w \u00d7 L\u00b2) \/ (8 \u00d7 T)\uff0c\u5176\u4e2d w \u662f\u7ebf\u6027\u91cd\u91cf\uff08\u5343\u514b\/\u7c73\uff09\uff0cL \u662f\u8de8\u5ea6\uff08\u7c73\uff09\uff0cT \u662f\u7535\u7f06\u4e2d\u7684\u5f20\u529b\u3002\u5bf9\u4e8e\u6211\u4eec\u7684\u60c5\u51b5\uff0cw = 10.5 \u5343\u514b\/\u7c73\uff0cL = 2.5 \u7c73\uff0c\u5047\u8bbe\u5408\u7406\u7684\u5f20\u529b T \u4e3a 500 N\uff08\u7ea6 50 \u5343\u514b\u529b\uff09\uff0c\u4e0b\u5782\u7ea6\u4e3a 80 \u6beb\u7c73\uff083.1 \u82f1\u5bf8\uff09\u3002\u8fd9\u5728\u53ef\u63a5\u53d7\u7684 1\u20132% \u8303\u56f4\u5185\uff082.5 \u7c73\u8de8\u5ea6 \u00d7 1\u20132% = 25\u201350 \u6beb\u7c73\u4e0b\u5782\uff09\uff0c\u867d\u7136\u5728\u6177\u6168\u4e00\u4fa7\u3002\u8bbe\u8ba1\u5e08\u53ef\u80fd\u4f1a\u5c06\u95f4\u9694\u51cf\u5c11\u5230 2.0 \u7c73\u4ee5\u5c06\u4e0b\u5782\u51cf\u5c11\u5230\u66f4\u4fdd\u5b88\u7684 50\u201360 \u6beb\u7c73\uff0c\u6216\u589e\u52a0\u652f\u6491\u7535\u7f06\u7cfb\u7edf\u4e2d\u7684\u5f20\u529b\u4ee5\u51cf\u5c11\u4e0b\u5782\u800c\u4e0d\u6539\u53d8\u7269\u7406\u95f4\u9694\u3002<\/p>\n\n    <p>A practical design spreadsheet or calculator tool that accepts cable weight (kg\/km), desired span length (m), and acceptable sag percentage can rapidly guide engineers to the right support spacing, dramatically shortening the design cycle and reducing errors that can cause installation delays.<\/p>\n    <p class=\"cn\">\u63a5\u53d7\u7535\u7f06\u91cd\u91cf\uff08\u5343\u514b\/\u5343\u7c73\uff09\u3001\u6240\u9700\u8de8\u5ea6\u957f\u5ea6\uff08\u7c73\uff09\u548c\u53ef\u63a5\u53d7\u4e0b\u5782\u767e\u5206\u6bd4\u7684\u5b9e\u9645\u8bbe\u8ba1\u7535\u5b50\u8868\u683c\u6216\u8ba1\u7b97\u5668\u5de5\u5177\u53ef\u4ee5\u5feb\u901f\u6307\u5bfc\u5de5\u7a0b\u5e08\u5230\u8fbe\u6b63\u786e\u7684\u652f\u6491\u95f4\u9694\uff0c\u5927\u5927\u7f29\u77ed\u8bbe\u8ba1\u5468\u671f\u5e76\u51cf\u5c11\u53ef\u80fd\u5bfc\u81f4\u5b89\u88c5\u5ef6\u8fdf\u7684\u9519\u8bef\u3002<\/p>\n\n\n    <!-- S9 -->\n    <h2 id=\"s9\">9.

The crane&#8217;s trolley must accelerate the cable weight along with the structural framework and the load being lifted. If the cable is lighter (say, a 3&#215;120 instead of 4&#215;185), the overall system mass decreases, requiring less motor power and acceleration time. If the cable is heavier (4&#215;185), the motor must work harder and acceleration takes longer. For a 400-meter traverse, the weight difference between a 3&#215;120 cable (roughly 7,000 kg\/km, or 2,800 kg for 400 m) and the 4&#215;185 (10,500 kg\/km, or 4,200 kg for 400 m) is 1,400 kg. Accelerating 1,400 kg of additional cable mass from 0 to operating speed in a fixed time budget requires additional motor power and higher peak currents, which can stress electrical components and reduce system reliability.<\/p>\n    <p class=\"cn\">\u8003\u8651\u4e00\u4e2a\u8bbe\u8ba1\u4e3a\u5728 60 \u79d2\u5185\u904d\u5386 400 \u7c73\u8de8\u5ea6\u7684\u96c6\u88c5\u7bb1\u8d77\u91cd\u673a\u2014\u2014\u6e2f\u53e3\u8fd0\u8425\u7684\u9ad8\u6548\u901f\u5ea6\u8981\u6c42\u3002\u8d77\u91cd\u673a\u7684\u6ed1\u8f6e\u8f66\u5fc5\u987b\u52a0\u901f\u7535\u7f06\u91cd\u91cf\u4ee5\u53ca\u7ed3\u6784\u6846\u67b6\u548c\u88ab\u63d0\u5347\u7684\u8d1f\u8f7d\u3002\u5982\u679c\u7535\u7f06\u8f83\u8f7b\uff08\u6bd4\u5982\uff0c3&#215;120 \u800c\u4e0d\u662f 4&#215;185\uff09\uff0c\u6574\u4f53\u7cfb\u7edf\u8d28\u91cf\u51cf\u5c11\uff0c\u9700\u8981\u8f83\u5c11\u7684\u7535\u52a8\u673a\u529f\u7387\u548c\u52a0\u901f\u65f6\u95f4\u3002\u5982\u679c\u7535\u7f06\u8f83\u91cd\uff084&#215;185\uff09\uff0c\u7535\u52a8\u673a\u5fc5\u987b\u66f4\u52aa\u529b\u5de5\u4f5c\uff0c\u52a0\u901f\u9700\u8981\u66f4\u957f\u65f6\u95f4\u3002\u5bf9\u4e8e 400 \u7c73\u7684\u904d\u5386\uff0c3&#215;120 \u7535\u7f06\uff08\u5927\u7ea6 7,000 \u5343\u514b\/\u5343\u7c73\uff0c\u6216 400 \u7c73\u7684 2,800 \u5343\u514b\uff09\u548c 4&#215;185\uff0810,500 \u5343\u514b\/\u5343\u7c73\uff0c\u6216 400 \u7c73\u7684 4,200 \u5343\u514b\uff09\u4e4b\u95f4\u7684\u91cd\u91cf\u5dee\u5f02\u662f 1,400 \u5343\u514b\u3002\u5728\u56fa\u5b9a\u65f6\u95f4\u9884\u7b97\u5185\u4ece 0 \u52a0\u901f 1,400 \u5343\u514b\u7684\u989d\u5916\u7535\u7f06\u8d28\u91cf\u5230\u8fd0\u884c\u901f\u5ea6\u9700\u8981\u989d\u5916\u7684\u7535\u52a8\u673a\u529f\u7387\u548c\u66f4\u9ad8\u7684\u5cf0\u503c\u7535\u6d41\uff0c\u8fd9\u53ef\u80fd\u4f1a\u7ed9\u7535\u6c14\u7ec4\u4ef6\u65bd\u52a0\u538b\u529b\u5e76\u964d\u4f4e\u7cfb\u7edf\u53ef\u9760\u6027\u3002<\/p>\n\n    <p>The choice of cable type therefore becomes not just an electrical decision (does it carry the required amperage?) but a mechanical and operational decision (does the system have enough power to accelerate the cable and meet speed targets?). For this reason, high-speed applications like STS cranes often push engineers to use larger conductors despite the weight penalty, because the increased ampacity allows smaller conductors in lower-speed applications, and the ampacity-to-weight trade-off heavily favors the larger conductor in high-current scenarios.<\/p>\n    <p class=\"cn\">\u56e0\u6b64\uff0c\u7535\u7f06\u7c7b\u578b\u7684\u9009\u62e9\u4e0d\u4ec5\u4ec5\u662f\u7535\u6c14\u51b3\u7b56\uff08\u5b83\u662f\u5426\u627f\u8f7d\u6240\u9700\u7684\u5b89\u57f9\u6570\uff1f\uff09\uff0c\u800c\u662f\u673a\u68b0\u548c\u8fd0\u8425\u51b3\u7b56\uff08\u7cfb\u7edf\u662f\u5426\u6709\u8db3\u591f\u7684\u7535\u529b\u52a0\u901f\u7535\u7f06\u5e76\u8fbe\u5230\u901f\u5ea6\u76ee\u6807\uff1f\uff09\u3002\u51fa\u4e8e\u8fd9\u4e2a\u539f\u56e0\uff0cSTS \u8d77\u91cd\u673a\u7b49\u9ad8\u901f\u5e94\u7528\u7ecf\u5e38\u63a8\u52a8\u5de5\u7a0b\u5e08\u4f7f\u7528\u66f4\u5927\u7684\u5bfc\u4f53\uff0c\u5c3d\u7ba1\u5b58\u5728\u91cd\u91cf\u60e9\u7f5a\uff0c\u56e0\u4e3a\u589e\u52a0\u7684\u8f7d\u6d41\u91cf\u5141\u8bb8\u5728\u8f83\u4f4e\u901f\u5ea6\u5e94\u7528\u4e2d\u4f7f\u7528\u8f83\u5c0f\u7684\u5bfc\u4f53\uff0c\u5728\u9ad8\u7535\u6d41\u573a\u666f\u4e2d\uff0c\u8f7d\u6d41\u91cf\u4e0e\u91cd\u91cf\u7684\u6743\u8861\u5f3a\u70c8\u503e\u5411\u4e8e\u8f83\u5927\u7684\u5bfc\u4f53\u3002<\/p>\n\n\n    <!-- S10 -->\n    <h2 id=\"s10\">10.

Instead, factors like delivery time, price, certification scope (Does the supplier hold DNV GL, ABS, or other relevant certifications?), and technical support quality should dominate the evaluation.<\/p>\n    <p class=\"cn\">\u5982\u8868\u6240\u793a\uff0c\u4e3b\u6d41\u5236\u9020\u5546\u4e4b\u95f4\u7684\u91cd\u91cf\u5dee\u5f02\u5f88\u5c0f\u2014\u2014\u6240\u6709 4&#215;185 \u7535\u7f06\u90fd\u5728 10,400\u201310,600 \u5343\u514b\/\u5343\u7c73\u8303\u56f4\u5185\uff08\u5927\u7ea6 7.0\u20137.1 \u78c5\/\u82f1\u5c3a\uff09\u3002Southwire \u793a\u4f8b\uff0811,200 \u5343\u514b\/\u5343\u7c73\uff09\u7565\u91cd\uff0c\u53cd\u6620\u4e86\u4ed6\u4eec\u4f7f\u7528\u66f4\u8010\u4e45\u7684\u5916\u62a4\u5957\u914d\u5236\u7684\u8bbe\u8ba1\u9009\u62e9\uff0c\u8fd9\u5728\u6076\u52a3\u73af\u5883\u4e2d\u63d0\u4f9b\u4e86\u989d\u5916\u7684\u4fdd\u62a4\uff0c\u4f46\u4ee3\u4ef7\u662f\u91cd\u91cf\u7565\u6709\u589e\u52a0\u3002\u5bf9\u4e8e\u5927\u591a\u6570\u5e94\u7528\uff0c\u4f9b\u5e94\u5546\u4e4b\u95f4\u7684 100\u2013200 \u5343\u514b\/\u5343\u7c73\u91cd\u91cf\u5dee\u5f02\u662f\u53ef\u5ffd\u7565\u7684\uff0c\u4e0d\u5e94\u63a8\u52a8\u91c7\u8d2d\u51b3\u7b56\u3002\u76f8\u53cd\uff0c\u4ea4\u4ed8\u65f6\u95f4\u3001\u4ef7\u683c\u3001\u8ba4\u8bc1\u8303\u56f4\uff08\u4f9b\u5e94\u5546\u662f\u5426\u6301\u6709 DNV GL\u3001ABS \u6216\u5176\u4ed6\u76f8\u5173\u8ba4\u8bc1\uff1f\uff09\u548c\u6280\u672f\u652f\u6301\u8d28\u91cf\u7b49\u56e0\u7d20\u5e94\u8be5\u4e3b\u5bfc\u8bc4\u4f30\u3002<\/p>\n\n\n    <!-- S11 -->\n    <h2 id=\"s11\">11.

This article has walked through the technical foundations of that specification\u2014understanding what constitutes the weight (7,104 kg\/km of copper plus 3,396 kg\/km of insulation and sheath), the VDE 0250-809 manufacturing standard that governs it, and the practical methods for translating that specification into real-world design calculations. We have illustrated how cable weight drives decisions about festoon rail sizing, trolley wheel ratings, motor power selection, and system acceleration profiles.

The actual weight of any individual cable can vary by \u00b15% to \u00b18% depending on the specific rubber compound formulation, the density of the materials used, and the precision of the extrusion process employed by the manufacturer.","protected":false},"author":1,"featured_media":8322,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"left","csco_page_header_type":"title","csco_page_load_nextpost":"","footnotes":""},"categories":[46,66,8],"tags":[57,44482,44053,45496,44507,45481,45482,45489,45501,45504,45503,45485,45488,43663,45483,45502,12577,34605,45486,45490,7458,44062,45492,8929,26473,45498,45505,31141,32146,44318,32356,45494,12856,5644,44305,45487,1092,1696,45484,14069,2692,45491,1032,45500,2604,45497,45495,45499,3195],"class_list":["post-8321","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cable-for-shore-connection-systems","category-common-problems-encountered-in-cable-applications","category-cranes-and-material-handling-cable","tag-ntsflcgewoeu","tag-ntsflcgewou-3","tag-0-6-1kv-flat-cable","tag-1kv-flexible-cable","tag-350-mcm-flat-cable","tag-4x185-festoon-cable","tag-4x185-flat-rubber-cable","tag-4x185mm2-crane-cable","tag-awg-festoon-cable-equivalent","tag-cable-dimension-chart","tag-cable-manufacturer-quotation","tag-container-crane-festoon-cable","tag-copper-weight-calculator","tag-copper-weight-kg-km","tag-crane-cable-4x185","tag-cross-section-4x185mm2","tag-din-vde-0298-4-current-capacity","tag-epr-insulated-flat-cable","tag-festoon-cable-weight-calculator","tag-festoon-system-power-cable","tag-festoon-trolley-cable","tag-flame-retardant-flat-cable","tag-flat-cable-thickness-width","tag-flat-flexible-cable","tag-flat-power-cable","tag-flexible-flat-cable-datasheet","tag-flexible-trailing-power-cable","tag-gantry-crane-flat-cable","tag-heavy-duty-festoon-cable","tag-heavy-duty-power-transmission","tag-heavy-duty-rubber-flat-cable","tag-heavy-duty-travelling-cable","tag-high-speed-festoon-cable","tag-industrial-trailing-cable","tag-international-cable-procurement","tag-kg-km-to-lbs-ft-cable-calculator","tag-material-handling-cable","tag-mobile-equipment-cable","tag-ntsflcgewou-4","tag-oil-resistant-rubber-cable","tag-overhead-crane-cable","tag-polychloroprene-outer-sheath-cable","tag-port-machinery-cable","tag-standard-awg-to-mm2-cable","tag-sts-crane-cable","tag-trailing-cable-parameters","tag-uv-resistant-festoon-cable","tag-vde-0250-flat-cable","tag-weather-resistant-crane-cable","cs-entry"],"_links":{"self":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/8321","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/comments?post=8321"}],"version-history":[{"count":2,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/8321\/revisions"}],"predecessor-version":[{"id":8324,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/posts\/8321\/revisions\/8324"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media\/8322"}],"wp:attachment":[{"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/media?parent=8321"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/categories?post=8321"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/feichuncables.com\/blog\/wp-json\/wp\/v2\/tags?post=8321"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
