cables, are specialized single-core cables specifically engineered for use in solar power generation systems. The SOLAR4 and SOLAR6 cables from Anhui Feichun Special Cable are designed to interconnect solar panels, junction boxes, and inverters in both residential and commercial photovoltaic installations. These cables must withstand the unique challenges of solar applications including continuous outdoor UV exposure, extreme temperature variations from freezing winters to scorching summers, and potential mechanical stress during installation and maintenance. Manufactured to EN 50618 standards, these cables feature tinned copper conductors that provide superior corrosion resistance and cross-linked insulation materials that ensure reliable performance throughout the typical 25+ year lifespan of solar installations.<\/p>\n <p class=\"zh\">\u5149\u4f0f\u96fb\u7e9c\uff0c\u4e5f\u7a31\u70ba PV \u96fb\u7e9c\uff0c\u662f\u5c08\u9580\u70ba\u592a\u967d\u80fd\u767c\u96fb\u7cfb\u7d71\u8a2d\u8a08\u7684\u55ae\u82af\u7279\u7a2e\u96fb\u7e9c\u3002\u5b89\u5fbd\u98db\u7d14\u7279\u7a2e\u96fb\u7e9c\u7684 SOLAR4 \u548c SOLAR6 \u96fb\u7e9c\u5c08\u70ba\u4f4f\u5b85\u548c\u5546\u696d\u5149\u4f0f\u5b89\u88dd\u4e2d\u7684\u592a\u967d\u80fd\u96fb\u6c60\u677f\u3001\u63a5\u7dda\u76d2\u548c\u9006\u8b8a\u5668\u4e4b\u9593\u7684\u4e92\u9023\u800c\u8a2d\u8a08\u3002\u9019\u4e9b\u96fb\u7e9c\u5fc5\u9808\u627f\u53d7\u592a\u967d\u80fd\u61c9\u7528\u7684\u7368\u7279\u6311\u6230\uff0c\u5305\u62ec\u6301\u7e8c\u7684\u6236\u5916\u7d2b\u5916\u7dda\u7167\u5c04\u3001\u5f9e\u56b4\u5bd2\u51ac\u5b63\u5230\u9177\u71b1\u590f\u5b63\u7684\u6975\u7aef\u6eab\u5ea6\u8b8a\u5316\uff0c\u4ee5\u53ca\u5b89\u88dd\u548c\u7dad\u8b77\u904e\u7a0b\u4e2d\u53ef\u80fd\u7684\u6a5f\u68b0\u61c9\u529b\u3002\u6309\u7167 EN 50618 \u6a19\u6e96\u88fd\u9020\uff0c\u9019\u4e9b\u96fb\u7e9c\u63a1\u7528\u934d\u932b\u9285\u5c0e\u9ad4\uff0c\u63d0\u4f9b\u512a\u8d8a\u7684\u8010\u8150\u8755\u6027\u80fd\uff0c\u4ea4\u806f\u7d55\u7de3\u6750\u6599\u78ba\u4fdd\u5728\u5178\u578b\u7684 25 \u5e74\u4ee5\u4e0a\u5149\u4f0f\u7cfb\u7d71\u58fd\u547d\u5167\u53ef\u9760\u904b\u884c\u3002<\/p>\n <\/div>\n\n <div class=\"cert-tags\">\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> EN 50618 Compliant<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> ISO 9001 Certified<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> T\u00dcV Compatible Design<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> UV Resistant<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> Weather Resistant<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> Halogen Free<\/span>\n <\/div>\n <\/div>\n\n <!-- Key Features -->\n <div class=\"card\">\n <h3 class=\"card-title\">Key Features & Benefits<span class=\"zh\">\u4e3b\u8981\u7279\u9ede\u8207\u512a\u52e2<\/span><\/h3>\n\n <div class=\"feature-grid\">\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\u2600\ufe0f<\/div>\n <div>\n <h5>Superior UV Resistance<span class=\"zh\">\u5353\u8d8a\u7684\u6297\u7d2b\u5916\u7dda\u6027\u80fd<\/span><\/h5>\n <p>Specially formulated outer sheath withstands continuous solar UV exposure for 25+ years without degradation or cracking.<\/p>\n <\/div>\n <\/div>\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\ud83c\udf21\ufe0f<\/div>\n <div>\n <h5>Extreme Temperature Range<span class=\"zh\">\u6975\u7aef\u6eab\u5ea6\u7bc4\u570d<\/span><\/h5>\n <p>Operates reliably from -40\u00b0C to +90\u00b0C, suitable for installations from arctic regions to desert climates.<\/p>\n <\/div>\n <\/div>\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\u26a1<\/div>\n <div>\n <h5>High Voltage Rating<span class=\"zh\">\u9ad8\u96fb\u58d3\u984d\u5b9a\u503c<\/span><\/h5>\n <p>1500V DC \/ 1000V AC rating supports modern high-efficiency solar systems and string configurations.<\/p>\n <\/div>\n <\/div>\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\ud83d\udd0b<\/div>\n <div>\n <h5>Tinned Copper Conductors<span class=\"zh\">\u934d\u932b\u9285\u5c0e\u9ad4<\/span><\/h5>\n <p>Tinning provides excellent corrosion resistance, ensuring consistent conductivity over decades of service.<\/p>\n <\/div>\n <\/div>\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\ud83d\udca7<\/div>\n <div>\n <h5>Weather & Water Resistant<span class=\"zh\">\u8010\u5019\u53ca\u9632\u6c34<\/span><\/h5>\n <p>Designed for permanent outdoor installation with resistance to rain, humidity, and atmospheric conditions.<\/p>\n <\/div>\n <\/div>\n <div class=\"feature-item\">\n <div class=\"icon-wrap\">\ud83d\udd25<\/div>\n <div>\n <h5>Flame Retardant Design<span class=\"zh\">\u963b\u71c3\u8a2d\u8a08<\/span><\/h5>\n <p>Cross-linked materials provide inherent flame retardancy and 200\u00b0C short circuit temperature tolerance.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n\n <!-- Common Specifications -->\n <div class=\"card\">\n <h3 class=\"card-title\">Common Technical Parameters<span class=\"zh\">\u901a\u7528\u6280\u8853\u53c3\u6578<\/span><\/h3>\n\n <div class=\"spec-grid\">\n <div class=\"spec-box\">\n <div class=\"val\">1000V AC<\/div>\n <div class=\"lbl\">AC Voltage<\/div>\n <div class=\"lbl-zh\">\u4ea4\u6d41\u96fb\u58d3<\/div>\n <\/div>\n <div class=\"spec-box\">\n <div class=\"val\">1500V DC<\/div>\n <div class=\"lbl\">DC Voltage<\/div>\n <div class=\"lbl-zh\">\u76f4\u6d41\u96fb\u58d3<\/div>\n <\/div>\n <div class=\"spec-box\">\n <div class=\"val\">-40\u00b0C<\/div>\n <div class=\"lbl\">Min.

With a current capacity of 70A, this cable is suitable for main DC feeders from combiner boxes, connections to central inverters, and any application where voltage drop over distance must be minimized. The larger conductor cross-section reduces resistive losses (3.39 \u03a9\/km compared to 5.09 \u03a9\/km for 4mm\u00b2), making it the preferred choice for systems where maximizing energy harvest efficiency is critical. Despite the increased conductor size, the cable maintains excellent flexibility with only a 6.1mm overall diameter, enabling straightforward routing and termination.<\/p>\n <p class=\"zh\">\u622a\u9762\u7a4d\u70ba 6mm\u00b2 \u7684 SOLAR6 \u96fb\u7e9c\u5c08\u70ba\u9700\u8981\u66f4\u9ad8\u8f09\u6d41\u91cf\u548c\u66f4\u9577\u96fb\u7e9c\u6577\u8a2d\u7684\u5927\u578b\u5546\u696d\u5b89\u88dd\u3001\u592a\u967d\u80fd\u8fb2\u5834\u548c\u516c\u7528\u4e8b\u696d\u898f\u6a21\u5149\u4f0f\u7cfb\u7d71\u800c\u8a2d\u8a08\u3002\u8a72\u96fb\u7e9c\u5177\u6709 70A \u7684\u8f09\u6d41\u91cf\uff0c\u9069\u7528\u65bc\u5f9e\u532f\u6d41\u7bb1\u51fa\u767c\u7684\u4e3b\u76f4\u6d41\u994b\u7dda\u3001\u8207\u96c6\u4e2d\u5f0f\u9006\u8b8a\u5668\u7684\u9023\u63a5\uff0c\u4ee5\u53ca\u4efb\u4f55\u9700\u8981\u6700\u5c0f\u5316\u8ddd\u96e2\u96fb\u58d3\u964d\u7684\u61c9\u7528\u3002\u8f03\u5927\u7684\u5c0e\u9ad4\u622a\u9762\u7a4d\u964d\u4f4e\u4e86\u96fb\u963b\u640d\u8017\uff083.39 \u03a9\/km\uff0c\u76f8\u6bd4 4mm\u00b2 \u7684 5.09 \u03a9\/km\uff09\uff0c\u4f7f\u5176\u6210\u70ba\u9700\u8981\u6700\u5927\u5316\u80fd\u91cf\u6536\u96c6\u6548\u7387\u7684\u7cfb\u7d71\u9996\u9078\u3002\u5118\u7ba1\u5c0e\u9ad4\u5c3a\u5bf8\u589e\u52a0\uff0c\u96fb\u7e9c\u4ecd\u4fdd\u6301\u51fa\u8272\u7684\u67d4\u97cc\u6027\uff0c\u5916\u5f91\u50c5\u70ba 6.1mm\uff0c\u4fbf\u65bc\u6577\u8a2d\u548c\u7aef\u63a5\u3002<\/p>\n <\/div>\n\n <div class=\"cert-tags\">\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> EN 50618<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> ISO 9001<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> 1500\/1500V DC<\/span>\n <span class=\"cert-tag\"><span class=\"icon\">\u2713<\/span> 1000\/1000V AC<\/span>\n <\/div>\n\n <h4 style=\"font-size: 1.05rem; margin: 26px 0 18px; color: var(--accent-solar);\">Complete Specifications<span style=\"font-family: 'Noto Sans TC', sans-serif; font-size: 0.88rem; color: var(--text-muted); font-weight: 400; margin-left: 12px;\">\u5b8c\u6574\u898f\u683c<\/span><\/h4>\n\n <div class=\"table-wrap\">\n <table>\n <thead>\n <tr>\n <th>Product Code<span class=\"unit\">\u7522\u54c1\u7de8\u78bc<\/span><\/th>\n <th>Core Size<span class=\"unit\">mm\u00b2<\/span><\/th>\n <th>Conductor<span class=\"unit\">\u5c0e\u9ad4\u985e\u578b<\/span><\/th>\n <th>Overall Dia.<span class=\"unit\">\u5916\u5f91 (mm)<\/span><\/th>\n <th>Current Capacity<span class=\"unit\">\u8f09\u6d41\u91cf (A)<\/span><\/th>\n <th>Resistance @20\u00b0C<span class=\"unit\">\u96fb\u963b (\u03a9\/km)<\/span><\/th>\n <th>Sheath Colour<span class=\"unit\">\u8b77\u5957\u984f\u8272<\/span><\/th>\n <th>Lengths<span class=\"unit\">\u9577\u5ea6 (m)<\/span><\/th>\n <\/tr>\n <\/thead>\n <tbody>\n <tr>\n <td class=\"code\">SOLAR6<\/td>\n <td>6<\/td>\n <td>Fine-Stranded Tinned Cu<\/td>\n <td>6.1<\/td>\n <td class=\"highlight\">70<\/td>\n <td>3.39<\/td>\n <td>Black \/ Red<\/td>\n <td>100, 500<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n <\/div>\n\n <div class=\"spec-grid\">\n <div class=\"spec-box\">\n <div class=\"val\">6 mm\u00b2<\/div>\n <div class=\"lbl\">Cross-Section<\/div>\n <div class=\"lbl-zh\">\u622a\u9762\u7a4d<\/div>\n <\/div>\n <div class=\"spec-box\">\n <div class=\"val\">70 A<\/div>\n <div class=\"lbl\">Current Capacity<\/div>\n <div class=\"lbl-zh\">\u8f09\u6d41\u91cf<\/div>\n <\/div>\n <div class=\"spec-box\">\n <div class=\"val\">6.1 mm<\/div>\n <div class=\"lbl\">Overall Diameter<\/div>\n <div class=\"lbl-zh\">\u5916\u5f91<\/div>\n <\/div>\n <div class=\"spec-box\">\n <div class=\"val\">3.39 \u03a9\/km<\/div>\n <div class=\"lbl\">Max.
