With a registered capital of 168 million RMB and state-of-the-art manufacturing facilities, FEICHUN Cable serves the global mining industry with products that meet the highest international standards including AS\/NZS, VDE, ICEA, and CAN\/CSA.<\/p>\n\n <p>Located in the Hefei Economic and Technological Development Zone’s Private Science and Technology Park, FEICHUN Cable benefits from strategic proximity to major transportation hubs\u2014just 15 minutes from Hefei Railway Station and South High-speed Railway Station, and one hour from Hefei Xinqiao Airport. This advantageous location facilitates rapid global delivery and customer service.<\/p>\n\n <h3>The TENAX-LUMEN Innovation<\/h3>\n <p>The TENAX-LUMEN series represents a revolutionary advancement in mining cable technology, addressing one of the industry’s most persistent safety challenges: cable visibility in dark or poorly lit environments. Mining operations frequently occur in conditions where standard cables are difficult or impossible to see, leading to accidental cable damage from crushing by mobile equipment, which causes production stoppages, costly repairs, and serious safety hazards.<\/p>\n\n <p>The TENAX-LUMEN (N)TSCGH3S 6\/10KV variant offers higher voltage capability compared to standard mining cables, making it ideal for larger equipment and extended power distribution systems. The 10kV rating (6\/10kV U0\/U, 12kV Um) provides the capacity to power heavy-duty draglines, large electric shovels, and other high-power mobile mining machinery operating in surface mines worldwide.<\/p>\n\n <div class=\"led-card\">\n <h3>\ud83c\udf1f Electroluminescent Technology Explained<\/h3>\n <p>Unlike reflective tapes or external lighting solutions, TENAX-LUMEN cables incorporate special electroluminescent (EL) strings directly into the cable structure. These EL strings emit a continuous, uniform glow along the entire cable length through a transparent polyurethane sheath, providing 360-degree visibility. The revolutionary aspect is that the illumination system operates independently of the main power conductors, meaning the cable remains visible even during power outages or when the equipment is de-energized\u2014critical for maintenance, emergency situations, and after-hours operations.<\/p>\n <\/div>\n <\/section>\n\n <section id=\"purpose\">\n <h2>Purpose and Applications<\/h2>\n \n <h3>Primary Applications<\/h3>\n <p>The FEICHUN TENAX-LUMEN 6\/10KV cable is specifically designed for demanding trailing and reeling applications in the mining and tunneling industries:<\/p>\n \n <ul>\n <li><strong>Electric Shovels:<\/strong> Powers large excavating equipment in surface mining operations, providing reliable 10kV power transmission with enhanced visibility to prevent cable runover incidents during shovel movement and digging operations<\/li>\n \n <li><strong>Draglines:<\/strong> Supplies high-voltage power to massive earthmoving equipment used in strip mining and open-pit coal operations. The self-illuminating feature is particularly valuable during night shifts when dragline cables are at greatest risk of damage<\/li>\n \n <li><strong>Large Mobile Equipment:<\/strong> Ideal for powering bucket-wheel excavators, walking draglines, and other heavy mining machinery requiring 10kV power distribution<\/li>\n \n <li><strong>Trailing Applications:<\/strong> Designed specifically for cables that trail behind mobile equipment, subject to flexing, dragging, and environmental exposure<\/li>\n \n <li><strong>Reeling Systems:<\/strong> Suitable for cable reel applications where repeated winding and unwinding occurs, with the luminescent feature providing visibility throughout the cable length on the reel<\/li>\n \n <li><strong>Tunneling Operations:<\/strong> Applicable for tunnel boring machines (TBM) and underground excavation equipment where lighting is limited and cable visibility is critical for safety<\/li>\n <\/ul>\n\n <h3>Why Self-Illuminating Cables Matter<\/h3>\n <div class=\"info-card\">\n <h4>The Safety and Economic Case<\/h4>\n <p>Industry studies and safety reports consistently identify cable damage from mobile equipment as a leading cause of unplanned downtime in surface mining operations.
