Кабель EpN 79 3×70+2×25+16мм² 3.6/6кВ: технические характеристики, конструкция и китайские аналоги шахтного экскаваторного кабеля
Complete technical breakdown flexible medium-voltage excavator cable EpN 79 configuration 3×70+2×25+16 mm² rated 3.6/6 kV (max 7.2 kV). Designed heavy excavators, rotary crushers, conveyor transfer bridges, drill rigs in open-pit and underground mining. Construction: 3 power phases (70 mm² tinned copper Class 5 stranded) → EPR insulation GM1b (max conductor temp 90°C) → 2 separate earth conductors (25 mm²) → 1 integrated pilot/monitoring core (16 mm², blue marking) for real-time cable condition monitoring → outer sheath heavy-duty polychloroprene rubber (Neoprene), resistant to abrasion, tear, mine water, oil, UV. Test voltage 15 kV/5 min. EpN 79 standard evolution from EpN 78, upgraded GM1b compound and optimized core geometry. Historical use: Eastern Europe (Czech, Slovakia, Poland), Middle East, CIS (Russia, Kazakhstan, Uzbekistan). Russian GOST equivalent КГЭШ 3.6/6 kV. Chinese equivalent Anhui Feichun Special Cable—full constructive copy with EAC/IEC certification. Cost European original €1,400–1,800/km vs Feichun €480–620/km (55–65% savings). Lead time Feichun 8–12 weeks vs European 16–24 weeks.



![PROTOLON (M)R-(N)TSCGEWOEU 6-35 KV 4 MYP cables must obtain MA (煤安) certification before they can be legally used in Chinese coal mines. The MA mark, administered by the National Coal Mine Safety Mark Office (煤矿安全标志办公室), represents mandatory safety certification for all underground coal mining equipment and materials. MYP cables, as mobile power supply cables for coal mining machinery, fall under the strictly regulated product categories defined in the Mining Product Safety Sign Management Catalog and must comply with Chinese national standards MT 818 series and GB 12972.[1][2] 是的,MYP电缆在中国煤矿使用前必须获得MA(煤安)认证。由国家煤矿安全标志办公室管理的MA标志,代表了所有井下煤矿设备和材料的强制性安全认证。MYP电缆作为煤矿机械的移动电源电缆,属于《矿用产品安全标志管理目录》中严格管制的产品类别,必须符合中国国家标准MT 818系列和GB 12972。](https://feichuncables.com/blog/wp-content/uploads/image-653.avif)
