This specialized cable maintains full operational capability in environments where standard cables would become dangerously brittle and fail.<\/p>\n \n <p>Mining and industrial operations in arctic regions, high-altitude locations, and extreme cold climates face unique challenges that demand specialized electrical infrastructure. The (-45\u00b0C) designation indicates this cable’s ability to maintain full flexibility during dynamic operation at temperatures down to -45\u00b0C, with fixed installation capability extending to an remarkable -60\u00b0C. This performance level addresses the needs of mining operations in Siberia, Northern Canada, Scandinavia, Alaska, and other regions where conventional cables simply cannot perform.<\/p>\n \n <div class=\"temp-comparison\">\n <div class=\"temp-card cold-card\">\n <h4>Flexible Operation<\/h4>\n <div class=\"temp-value\">-45\u00b0C<\/div>\n <div class=\"temp-label\">Dynamic use with continuous movement<\/div>\n <\/div>\n <div class=\"temp-card cold-card\">\n <h4>Fixed Installation<\/h4>\n <div class=\"temp-value\">-60\u00b0C<\/div>\n <div class=\"temp-label\">Static mounting in extreme cold<\/div>\n <\/div>\n <\/div>\n \n <p>The fundamental challenge of cold-temperature cable operation lies in the behavior of polymer materials at low temperatures. As temperatures drop, rubber and plastic compounds undergo a process called glass transition, where they lose flexibility and become rigid and brittle. According to materials science research, amorphous forms of EPR (Ethylene Propylene Rubber) are flexible at low temperatures, with glass transition points around -60\u00b0C (source: <a href=\"https:\/\/en.wikipedia.org\/wiki\/Ethylene_propylene_rubber\" rel=\"nofollow noopener\" target=\"_blank\">Wikipedia – Ethylene Propylene Rubber<\/a>). The PROTOMONT EMV-FC (-45\u00b0C) utilizes specially formulated EPR compounds that exploit this property, maintaining flexibility well below the temperatures that would render standard cables inoperable.<\/p>\n \n <div class=\"highlight-box cold\">\n <h4>Why Extreme Cold Capability Matters<\/h4>\n <p>In arctic mining operations, ambient temperatures can drop to -50\u00b0C or below. If a cable loses flexibility in these conditions, it cannot be moved, rerouted, or connected without risk of cracking the insulation or outer sheath. A single crack can compromise the EMC shield effectiveness, allow moisture ingress, and lead to catastrophic cable failure. The (-45\u00b0C) flexible rating ensures this cable can be safely handled and operated throughout the harshest arctic winters.<\/p>\n <\/div>\n \n <h2 id=\"purpose\">Purpose and Primary Applications<\/h2>\n \n <p>The PROTOMONT EMV-FC (N)SSHCOEU (-45\u00b0C) 1 kV cable is purpose-engineered for powering VFD-controlled motors in extreme cold environments where both electromagnetic compatibility and low-temperature performance are critical requirements.<\/p>\n \n <h3>Primary Application Environments<\/h3>\n \n <p>This cable excels in demanding cold-climate scenarios that would compromise standard VFD cables. For <strong>arctic and sub-arctic mining operations<\/strong>, it powers equipment in northern mineral extraction operations including gold, diamond, and rare earth mining in regions like Siberia, Northern Canada, Alaska, and Scandinavia. In <strong>high-altitude mining installations<\/strong>, it serves operations above 3,000 meters where temperatures drop dramatically, such as Andean copper mines and Himalayan mining projects. The cable supports <strong>cold storage and refrigeration facilities<\/strong> by powering VFD-controlled compressor motors in industrial freezer installations operating at -40\u00b0C or below. For <strong>winter construction projects<\/strong>, it enables reliable operation of VFD-controlled equipment during construction in extreme cold conditions. It also serves <strong>polar research stations<\/strong> and other installations in Antarctic and Arctic research facilities requiring reliable power transmission.<\/p>\n \n <p>Temperature variations present a significant challenge in mining operations, with underground environments potentially ranging from near-freezing conditions in some mines to elevated temperatures in others. Surface operations may experience even greater temperature extremes (source: <a href=\"https:\/\/www.amplexmining.com.au\/bs-6708-type-321-mining-cable\" rel=\"dofollow noopener\" target=\"_blank\">Amplex Mining Australia – BS 6708 Type 321 Mining Cable<\/a>).<\/p>\n \n <h3>VFD Motor Applications in Cold Climates<\/h3>\n \n <p>Variable Frequency Drives are particularly valuable in cold climate operations where energy efficiency is crucial and fuel costs for heating are already substantial. VFD-controlled motors in cold environments include conveyor system drives operating in outdoor mineral processing, pump motors for dewatering in permafrost conditions, ventilation fan motors in underground mines with cold air intake, material handling equipment operating in sub-zero temperatures, and compressor motors in refrigeration and cryogenic applications.<\/p>\n \n <h3>Continuous Movement Applications<\/h3>\n \n <p>Like its standard-temperature counterpart, this cable is specifically designed for applications involving continuous movement. The cable maintains its flexibility for laying on material handling equipment, even with continuous movement such as in cable booms or as connection between upper and lower cars. In cold climates, this continuous movement capability while maintaining flexibility is particularly challenging and represents one of the cable’s key engineering achievements.<\/p>\n \n <h3>Submersion Capability<\/h3>\n \n <p>The cable maintains its water resistance rating, capable of operation in water up to 40\u00b0C at depths of approximately 10 meters. This capability, combined with extreme cold resistance, makes it suitable for dewatering operations in permafrost regions where groundwater temperatures remain low year-round.<\/p>\n \n <h2 id=\"cold-temperature\">Cold Temperature Performance Analysis<\/h2>\n \n <p>Understanding the cold-temperature performance of the PROTOMONT EMV-FC (-45\u00b0C) requires examination of both the materials science and the practical engineering considerations that enable operation in extreme cold.<\/p>\n \n <h3>Temperature Range Comparison<\/h3>\n \n <div class=\"comparison-table\">\n <table>\n <caption style=\"text-align: left; margin-bottom: 15px; color: var(--text-secondary);\">Table 1: Temperature Performance Comparison – Standard vs. (-45\u00b0C) Version<\/caption>\n <thead>\n <tr>\n <th>Parameter<\/th>\n <th>Standard EMV-FC<\/th>\n <th>(-45\u00b0C) Version<\/th>\n <th>Improvement<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Min.

The PROTOLON EPR (Ethylene Propylene Rubber) insulation and specialized rubber compounds used throughout the cable construction are formulated to resist glass transition at extreme low temperatures.<\/p>\n \n <p>EPR has a wide thermal range typically in the region of -55\u00b0C to 150\u00b0C. The material maintains flexibility because unlike crystalline polymers, the amorphous structure of properly formulated EPR compounds does not undergo the sharp phase transitions that cause standard materials to become brittle (source: <a href=\"https:\/\/www.elandcables.com\/the-cable-lab\/faqs\/faq-what-are-the-benefits-of-epr-insulated-cables\" rel=\"nofollow noopener\" target=\"_blank\">Eland Cables – Benefits of EPR Insulated Cables<\/a>).<\/p>\n \n <p>Research into EPR compound formulation confirms that EPR has excellent cold resistance, maintaining good flexibility even at -50\u00b0C (source: <a href=\"https:\/\/zwcables.com\/epr-cable\/\" rel=\"nofollow noopener\" target=\"_blank\">ZW Cables – EPR Cable Benefits<\/a>). The (-45\u00b0C) variant of the PROTOMONT EMV-FC utilizes optimized compound formulations that push this performance even further.<\/p>\n \n <h3>Practical Cold Operation Considerations<\/h3>\n \n <p>While the cable maintains flexibility at -45\u00b0C for dynamic applications, several practical considerations apply. Storage temperature before installation affects initial flexibility. Pre-warming cables stored in extremely cold conditions can ease installation. The thermal mass of the cable means it responds slowly to temperature changes. In applications transitioning between warm equipment rooms and cold exterior conditions, allow stabilization time. Impact resistance decreases at lower temperatures even when flexibility is maintained. Avoid dropping or striking the cable at extreme low temperatures.<\/p>\n \n <h2 id=\"characteristics\">Key Characteristics and Features<\/h2>\n \n <p>The PROTOMONT EMV-FC (N)SSHCOEU (-45\u00b0C) combines extreme cold performance with all the EMC and mechanical features of the standard EMV-FC series.<\/p>\n \n <h3>EMC-Optimized Shielding System<\/h3>\n \n <p>The cable features a concentric braid of tinned copper wires specifically optimized for electromagnetic compatibility. This shield design is critical for VFD applications where high-frequency PWM switching creates electromagnetic noise that must be contained.<\/p>\n \n <p>For effective noise containment, shielded VFD cables should include a copper braid, foil shield, or both. Copper braid provides low impedance at high frequencies, essential for containing the electromagnetic emissions from modern high-frequency VFD switching (source: <a href=\"https:\/\/www.kebamerica.com\/blog\/grounding-and-power-cable-guidelines\/\" rel=\"nofollow noopener\" target=\"_blank\">KEB America – VFD Cable Requirements<\/a>).<\/p>\n \n <p>The tinned copper braid maintains its shielding effectiveness across the entire temperature range, with the tinning providing essential corrosion protection in environments where temperature cycling might otherwise promote condensation and corrosion.<\/p>\n \n <h3>Split Protective Earth Conductor Design<\/h3>\n \n <p>The unique arrangement of three power cores laid up with protective earth conductors split into three in the outer interstices provides several advantages. This configuration delivers symmetrical grounding essential for EMC performance, maintains cable balance across extreme temperature variations, ensures adequate cross-sectional area for fault current capacity, and enables optimal cable geometry for both mechanical flexibility and electrical performance throughout the temperature range.<\/p>\n \n <h3>Black Outer Sheath<\/h3>\n \n <p>Unlike the standard EMV-FC with its yellow outer sheath, the (-45\u00b0C) version features a black PROTOFIRM outer sheath. This coloring choice serves practical purposes in cold climate applications where black absorbs more solar radiation, potentially helping to warm the cable surface during cold daylight hours. The black sheath also provides better visibility against snow and ice backgrounds common in arctic operations.<\/p>\n \n <div class=\"comparison-table\">\n <table>\n <caption style=\"text-align: left; margin-bottom: 15px; color: var(--text-secondary);\">Table 2: Key Characteristics Summary<\/caption>\n <thead>\n <tr>\n <th>Feature<\/th>\n <th>Specification<\/th>\n <th>Benefit<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Cold Flexibility<\/td>\n <td class=\"cold-value\">-45\u00b0C flexible operation<\/td>\n <td>Arctic\/sub-arctic operation capability<\/td>\n <\/tr>\n <tr>\n <td>Fixed Installation<\/td>\n <td class=\"cold-value\">-60\u00b0C minimum<\/td>\n <td>Permanent installations in extreme cold<\/td>\n <\/tr>\n <tr>\n <td>EMC Shield<\/td>\n <td class=\"emc-value\">Concentric tinned copper braid<\/td>\n <td>High-frequency noise containment<\/td>\n <\/tr>\n <tr>\n <td>Earth Conductor<\/td>\n <td class=\"spec-value\">Split into 3 in outer interstices<\/td>\n <td>Symmetrical grounding, EMC optimization<\/td>\n <\/tr>\n <tr>\n <td>Outer Sheath Color<\/td>\n <td class=\"spec-value\">Black<\/td>\n <td>Visibility on snow, solar heat absorption<\/td>\n <\/tr>\n <tr>\n <td>Water Resistance<\/td>\n <td class=\"spec-value\">~10m depth at 40\u00b0C water<\/td>\n <td>Submersible pump applications<\/td>\n <\/tr>\n <tr>\n <td>Certifications<\/td>\n <td class=\"spec-value\">MSHA P-189-3, EAC<\/td>\n <td>Global mining compliance<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n \n <h2 id=\"material-structure\">Material Structure and Construction<\/h2>\n \n <p>The construction of the PROTOMONT EMV-FC (N)SSHCOEU (-45\u00b0C) employs specially formulated materials throughout each layer to achieve its extreme cold performance while maintaining all electrical and mechanical specifications.<\/p>\n \n <div class=\"layer-diagram\">\n <h4>Cable Cross-Section Layer Structure (Cold-Optimized)<\/h4>\n <div class=\"layer-list\">\n <div class=\"layer\">\n <span class=\"layer-num cold-layer\">1<\/span>\n <span>Finely stranded tinned copper conductor (Class 5) – maintains conductivity at extreme cold<\/span>\n <\/div>\n <div class=\"layer\">\n <span class=\"layer-num cold-layer\">2<\/span>\n <span>PROTOLON EPR insulation (3GI3) – cold-optimized compound, flexible to -45\u00b0C<\/span>\n <\/div>\n <div class=\"layer\">\n <span class=\"layer-num\">3<\/span>\n <span>Three power cores + split PE conductors in outer interstices<\/span>\n <\/div>\n <div class=\"layer\">\n <span class=\"layer-num emc-layer\">4<\/span>\n <span>EMC-optimized concentric tinned copper braid screen<\/span>\n <\/div>\n <div class=\"layer\">\n <span class=\"layer-num cold-layer\">5<\/span>\n <span>EPR inner sheath (GM1B) – cold-resistant vulcanized rubber<\/span>\n <\/div>\n <div class=\"layer\">\n <span class=\"layer-num cold-layer\">6<\/span>\n <span>PROTOFIRM CR outer sheath (5GM5) – Black, cold-resistant elastomer<\/span>\n <\/div>\n <\/div>\n <\/div>\n \n <h3>Cold-Optimized Conductor Design<\/h3>\n \n <p>The conductor utilizes finely stranded tinned copper conforming to Class 5 flexibility standards per DIN EN 60228.

Copper conductor resistance decreases approximately 0.4% per \u00b0C of temperature reduction. At -45\u00b0C versus 20\u00b0C, conductor resistance is reduced by approximately 26%, resulting in lower I\u00b2R losses and slightly improved current-carrying capacity. EPR insulation maintains its dielectric strength at low temperatures, with some studies indicating improved performance. The cold-induced reduction in molecular mobility can actually enhance insulation resistance.<\/p>\n \n <h3>VFD Compatibility in Cold Conditions<\/h3>\n \n <p>The cable’s EMC shielding effectiveness is maintained across the full temperature range. This is critical because VFD systems operating in cold environments may actually generate more electrical noise due to increased switching transients in cold power electronics. The cable’s ability to contain these emissions ensures EMC compliance regardless of ambient temperature.<\/p>\n \n <h2 id=\"thermal-parameters\">Complete Thermal Parameters<\/h2>\n \n <p>The thermal specifications of the PROTOMONT EMV-FC (N)SSHCOEU (-45\u00b0C) define its operational envelope across both temperature extremes.<\/p>\n \n <div class=\"comparison-table\">\n <table>\n <caption style=\"text-align: left; margin-bottom: 15px; color: var(--text-secondary);\">Table 4: Complete Thermal Specifications<\/caption>\n <thead>\n <tr>\n <th>Parameter<\/th>\n <th>Value<\/th>\n <th>Application Consideration<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Max.

Impact resistance is reduced at extreme cold. Even flexible materials become more susceptible to impact damage at low temperatures. Avoid dropping tools or materials on the cable in cold conditions. In extreme cold, slightly increasing the bending radius beyond the minimum specification provides additional safety margin. Cold conditions reduce the effectiveness of self-sealing in minor sheath damage.

When cables have been stored at extremely low temperatures (below -30\u00b0C), consider warming them in a heated enclosure before installation to ease handling. Rapid temperature changes can stress cable materials. When moving cables from warm storage to extreme cold, allow gradual acclimatization. Cold weather reduces the effectiveness of some lubricants. Ensure any cable pulling compounds are rated for the installation temperature.<\/p>\n \n <p>Installation should be avoided at temperatures below the rated flexible operation limit to prevent potential cracking of the insulation or sheath materials. For this cable, that limit is -45\u00b0C for flexible installation. If installation must proceed in conditions approaching this limit, extra care and slower handling speeds are essential (source: <a href=\"https:\/\/www.reelingcable.com\/coal-cutter-cables-protomont-v-nsshcgeoeu-new-061kv-for-underground-use\" rel=\"dofollow noopener\" target=\"_blank\">Reeling Cable Technical Resources<\/a>).<\/p>\n \n <h3>EMC-Specific Installation Requirements<\/h3>\n \n <p>The EMC installation requirements remain the same as the standard EMV-FC, but with additional considerations for cold environments. EMC cable glands must be rated for the operating temperature range. Standard glands may not seal properly at extreme cold. Shield bonding connections must account for thermal expansion\/contraction cycles. Grounding system impedance should be verified at operating temperature as soil conditions in permafrost regions can affect grounding effectiveness.<\/p>\n \n <div class=\"highlight-box warning\">\n <h4>Cold Climate Grounding Considerations<\/h4>\n <p>In permafrost regions, ground resistance can be significantly higher than in temperate climates. The EMC shield grounding system must be designed to provide effective high-frequency grounding despite potentially elevated ground resistance. Consult with a qualified electrical engineer familiar with cold-climate installations.<\/p>\n <\/div>\n \n <h3>Operational Best Practices for Cold Environments<\/h3>\n \n <p>During operation in extreme cold, several best practices enhance cable longevity and safety. Regular visual inspection for any signs of cracking or damage to the outer sheath is important. If the cable is used in reeling applications, monitor reel drum temperature to avoid thermal shock. Maintain records of operating temperatures to establish baseline conditions and identify anomalies.<\/p>\n \n <h2 id=\"comparison\">Cable Selection Comparison<\/h2>\n \n <p>Understanding when to specify the (-45\u00b0C) variant versus standard cables helps ensure optimal performance and cost-effectiveness.<\/p>\n \n <div class=\"comparison-table\">\n <table>\n <caption style=\"text-align: left; margin-bottom: 15px; color: var(--text-secondary);\">Table 8: Cable Selection Guide by Application Temperature<\/caption>\n <thead>\n <tr>\n <th>Operating Environment<\/th>\n <th>Recommended Cable<\/th>\n <th>Rationale<\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td>Temperate climate (>-20\u00b0C)<\/td>\n <td>Standard EMV-FC<\/td>\n <td>Cost-effective for moderate conditions<\/td>\n <\/tr>\n <tr>\n <td>Cold climate (-20\u00b0C to -35\u00b0C)<\/td>\n <td>Standard EMV-FC<\/td>\n <td>Within standard operating range<\/td>\n <\/tr>\n <tr>\n <td>Severe cold (-35\u00b0C to -45\u00b0C)<\/td>\n <td class=\"cold-value\">EMV-FC (-45\u00b0C)<\/td>\n <td>Required for safe flexible operation<\/td>\n <\/tr>\n <tr>\n <td>Extreme cold (<-45\u00b0C)<\/td>\n <td class=\"cold-value\">EMV-FC (-45\u00b0C) fixed only<\/td>\n <td>Flexible operation not recommended<\/td>\n <\/tr>\n <tr>\n <td>Arctic mining (variable)<\/td>\n <td class=\"cold-value\">EMV-FC (-45\u00b0C)<\/td>\n <td>Covers full seasonal range<\/td>\n <\/tr>\n <tr>\n <td>Industrial freezer VFD systems<\/td>\n <td class=\"cold-value\">EMV-FC (-45\u00b0C)<\/td>\n <td>Continuous cold exposure<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n \n <p>Mining environments often expose cables to harsh conditions.

This is 20\u00b0C lower than the standard EMV-FC version (-25\u00b0C). The designation specifically refers to the flexible operation limit; for fixed installations, the cable can operate at even lower temperatures down to -60\u00b0C. This makes it suitable for arctic mining, high-altitude operations, and other extreme cold environments.\n <\/div>\n <\/div>\n \n <div class=\"faq-item\">\n <div class=\"faq-question\">Why is the outer sheath black instead of yellow?<\/div>\n <div class=\"faq-answer\">\n The black outer sheath on the (-45\u00b0C) variant serves several purposes for cold-climate operations. Black absorbs more solar radiation than yellow, potentially helping to warm the cable surface during cold daylight hours. Black also provides better visibility contrast against snow and ice backgrounds typical of arctic environments. The black coloring also visually distinguishes the cold-resistant variant from standard EMV-FC cables in inventory, preventing accidental specification errors.\n <\/div>\n <\/div>\n \n <div class=\"faq-item\">\n <div class=\"faq-question\">Can this cable be used in warm climates too?<\/div>\n <div class=\"faq-answer\">\n Yes, the (-45\u00b0C) variant maintains the same high-temperature ratings as the standard EMV-FC: +60\u00b0C for flexible operation and +80\u00b0C for fixed installation, with 90\u00b0C maximum conductor temperature. The cold-resistant formulation does not compromise high-temperature performance. However, for applications that will never experience extreme cold, the standard EMV-FC may be more cost-effective.\n <\/div>\n <\/div>\n \n <div class=\"faq-item\">\n <div class=\"faq-question\">What happens if I flex the cable below -45\u00b0C?<\/div>\n <div class=\"faq-answer\">\n Below -45\u00b0C, the cable materials approach their glass transition zone where flexibility significantly decreases. Flexing the cable in this condition risks cracking the outer sheath and potentially the insulation. Such cracks would compromise the EMC shield effectiveness, allow moisture ingress, and significantly reduce cable life. If operation below -45\u00b0C is required, the cable should be used only in fixed installations where no flexing occurs, and ambient temperatures should not drop below -60\u00b0C even for fixed use.\n <\/div>\n <\/div>\n \n <div class=\"faq-item\">\n <div class=\"faq-question\">Is the EMC shielding effectiveness affected by extreme cold?<\/div>\n <div class=\"faq-answer\">\n The EMC shielding effectiveness of the tinned copper braid is maintained across the full temperature range. Copper’s electrical conductivity actually improves slightly at lower temperatures due to reduced electron scattering, potentially providing marginally better shielding performance in cold conditions. The tinning prevents corrosion that could otherwise result from condensation during temperature cycling. The critical factor is maintaining shield integrity by avoiding mechanical damage, which requires following proper handling procedures at low temperatures.\n <\/div>\n <\/div>\n \n <div class=\"faq-item\">\n <div class=\"faq-question\">What special storage requirements exist for this cable?<\/div>\n <div class=\"faq-answer\">\n The (-45\u00b0C) cable can be stored at any temperature within its operational range. However, if stored at extremely low temperatures and rapid deployment is required, consider warming the cable drums in a heated enclosure before installation to ease handling. Avoid storing cable reels outdoors where they may be covered by snow or ice that could damage the outer sheath when the reel is moved. Standard cable storage practices (keeping reels upright, protecting from UV if stored outdoors in summer, etc.) also apply.\n <\/div>\n <\/div>\n <\/div>\n \n <h2 id=\"conclusion\">Conclusion<\/h2>\n \n <p>The PROTOMONT EMV-FC (N)SSHCOEU (-45\u00b0C) 1 kV cable represents the apex of cold-climate VFD cable engineering, combining the electromagnetic compatibility features essential for frequency converter applications with exceptional low-temperature performance that enables operation in the world’s most extreme environments.<\/p>\n \n <p>The cable’s ability to maintain full flexibility at -45\u00b0C for dynamic applications and withstand fixed installation at -60\u00b0C opens possibilities for mining, industrial, and construction operations in arctic regions that were previously limited by cable capabilities.

These cables address one of the most significant challenges in modern industrial power distribution: electromagnetic compatibility in high-frequency switching environments.\nVariable Frequency Drives have revolutionized motor control in mining, construction, and industrial applications by providing precise speed regulation and energy efficiency. However, VFDs also introduce unique electrical challenges. As noted by cable engineering specialists, VFDs require specialized cabling to ensure reliable operation, minimize electromagnetic interference, and maintain safety for the system as a whole, because selecting the right cables and proper installation directly impact performance and equipment longevity (source: KEB America).\nThe PROTOMONT EMV-FC series specifically addresses these challenges through its EMC-optimized concentric braid screen design, making it the ideal choice for frequency converter controlled drives in the mining industry, on construction sites, and similar applications with heavy mechanical stresses.","protected":false},"author":1,"featured_media":2316,"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":[66,222,94,165,35,464,209,97,722,93,7,1,56,9,101],"tags":[6401,6400,6398,6327,6381,6288,6370,6366,6325,6367,6354,6329,6332,1759,6323,6369,6372,1701,6385,6060,6342,6377,16,798,6387,6364,6320,6390,6335,6375,6331,6347,6340,6374,6319,6336,6373,6396,6397,820,6368,145,171,4491,6353,3826,6344,6358,6321,6351,6379,6252,152,6333,6339,107,176,6391,6361,6324,1092,6386,111,139,6363,6359,214,204,6355,6393,6337,6341,6322,6388,6395,6285,6061,6394,5438,6348,6326,17,6371,4605,6378,6349,5558,5525,6345,6318,6338,6330,6365,6334,2790,919,6346,6328,1247,6383,6389,1088,6352,6384,6350,6376,6382,6360,6362,6357,6343],"class_list":["post-2397","post","type-post","status-publish","format-standard","has-post-thumbnail","category-common-problems-encountered-in-cable-applications","category-as-nzs-1802-reeling-cables-for-underground-mining","category-din-vde-0250-mining-cable","category-drag-chain-cable","category-festoon-cable","category-flexible-cables-with-high-bending-life-and-fatigue-resistance","category-icea-s-75-381-portable-power-cables","category-lszh-low-smoke-zero-halogen-flexible-cable","category-marine-cables","category-mining-cable-with-self-sufficient-leds","category-mining-trailing-cable","category-uncategorized","category-reeling-cable","category-spreader-basket-reel-cable","category-submersible-pump-cable","tag-nsshcoeu-45c","tag-nsshcoeu-45c-1-kv","tag-nsshcoeu-1kv","tag-0-6-1kv-vfd-cable","tag-360-degree-shield-bonding-cable","tag-3gi3-compound-insulation","tag-5gm5-outer-sheath","tag-5kv-test-voltage-cable","tag-640-1140v-mining-cable","tag-90c-conductor-temperature-vfd-cable","tag-anhui-vfd-cable-manufacturer","tag-cable-boom-cable","tag-china-vfd-cable-manufacturer","tag-chloroprene-rubber-sheath","tag-class-5-flexible-cable","tag-class-5-flexible-vfd-cable","tag-concentric-screen-cable","tag-construction-site-cable","tag-construction-vfd-cable","tag-continuous-movement-cable","tag-copper-braid-screened-cable-for-inverter-controlled-motors","tag-copper-braid-shield-cable","tag-din-vde-0250","tag-din-vde-0250-812","tag-din-vde-0250-812-vfd-cable","tag-drilling-equipment-vfd-cable","tag-eac-certificate","tag-eac-certified-mining-cable","tag-electromagnetic-compatibility","tag-electromagnetic-compatibility-cable","tag-emc-copper-braid-shield","tag-emc-mining-cable-comparison","tag-emc-optimized-rubber-sheathed-cable-for-variable-frequency-drives","tag-emc-shielded-cable","tag-emc-shielded-mining-cable","tag-emi-shielding","tag-emi-shielding-cable","tag-emv-fc-frequency-converter-cable","tag-emv-fc-mining-cable","tag-epr-insulated-cable","tag-epr-insulated-vfd-cable","tag-epr-insulation","tag-explosion-proof-mining-cable","tag-feichun-cable","tag-feichun-emc-cable","tag-feichun-special-cable","tag-flexible-emc-cable-for-cable-boom-continuous-movement","tag-frequency-controlled-drive-cable","tag-frequency-converter-cable","tag-frequency-converter-cable-selection","tag-frequency-converter-emc-cable","tag-gm1b-inner-sheath","tag-heavy-duty-mining-cable","tag-heavy-duty-vfd-cable","tag-heavy-duty-vfd-motor-cable-for-mining-applications","tag-heavy-duty-e-loader-mining-cable","tag-icea-s-75-381-2","tag-iec-60332-1-2-flame-retardant-vfd-cable","tag-inverter-fed-motor-cable","tag-inverter-motor-cable","tag-material-handling-cable","tag-material-handling-vfd-cable","tag-mining-cable","tag-mining-cables","tag-mining-conveyor-vfd-cable","tag-mining-motor-cable","tag-mining-power-cable","tag-mining-trailing-cable","tag-mining-vfd-cable-supplier-asia","tag-msha-approved-vfd-cable","tag-msha-certified","tag-msha-certified-emc-shielded-frequency-converter-cable","tag-msha-p-189-3","tag-msha-p-189-3-certified-cable","tag-nsscoeu-vfd-cable","tag-protolon-epr-insulation","tag-protolon-insulation","tag-protomont-emc-cable","tag-protomont-emv-fc","tag-protomont-emv-fc-vs-standard-vfd","tag-pwm-motor-cable","tag-reeling-cable","tag-rubber-sheathed-emc-cable","tag-screened-mining-cable","tag-shielded-motor-cable","tag-shielded-vs-unshielded-vfd-cable","tag-split-earth-conductor","tag-split-earth-conductor-cable","tag-split-protective-earth-conductor-vfd-cable-design","tag-sshcoeu-cable","tag-sshcoeu-vfd-cable","tag-submersible-vfd-cable","tag-submersible-vfd-cable-10m","tag-symmetrical-ground-cable","tag-tinned-copper-conductor","tag-tinned-copper-conductor-cable","tag-tinned-copper-conductor-frequency-converter-mining-cable","tag-underground-mining-vfd-cable","tag-variable-frequency-drive-cable","tag-variable-frequency-drive-cable-mining","tag-vde-mining-emc-cable","tag-vfd-cable","tag-vfd-cable-china-manufacturer","tag-vfd-cable-underground-mining","tag-vfd-cable-vs-standard-cable","tag-vfd-emc-cable","tag-vfd-motor-cable","tag-vfd-pump-cable","tag-vfd-reel
