Medium Voltage Underground XLPE Insulated Aluminum Power Cable: 10kv-25kv, 3X70mm² to 500mm² 3-Core for Subterranean Transmission​ This range of medium-voltage underground power cables, insulated with XLPE (cross-linked polyethylene) and featuring aluminum conductors, is engineered for reliable subterranean power transmission across 10kv, 15kv, 24kv, and 25kv applications. Available in 3-core configurations with conductor cross-sections from 3X70mm² to 500mm²—including 3X120mm², 120mm², 240mm², and 500mm²—these cables balance durability, efficiency, and space-saving design for urban, industrial, and infrastructure projects.​ XLPE insulation is a standout feature, offering superior thermal stability (-40°C to 90°C), high dielectric strength, and resistance to moisture, soil chemicals, and mechanical stress—critical for underground environments prone to corrosion and pressure. The aluminum conductors provide cost-effectiveness and lightweight properties, reducing installation complexity while maintaining efficient current carrying, suitable for medium-voltage load demands.​ The 3-core design consolidates phases into a single cable, minimizing underground duct space and simplifying installation in crowded urban grids or industrial zones. With robust construction, these cables withstand burial pressures, rodent damage, and soil abrasion, ensuring long-term performance in subway systems, residential districts, and industrial parks.​ Compliant with international standards, the range caters to diverse project scales, from urban grid expansions to industrial power distribution. Its tailored specifications—voltage ratings, conductor sizes, and core design—make it a versatile solution for reliable underground medium-voltage transmission.
