This is a 15kV 3-core 300 sqmm armored power cable with XLPE insulation, designed for underground installation. It offers excellent electrical performance and mechanical protection, with an armored structure that enhances crush and impact resistance, making it suitable for demanding underground environments. Widely used in industrial power distribution, urban grids, and tunnel projects.

Copper cable series such as Cu U1000 Rvfv, Arvfv, Rvfv-K, and Xav, covering specifications like 1X95mm² and 1X300mm², are armoured cables designed for underground laying, with both high-power transmission and environmental adaptability.​ The conductor is made of high-purity copper with excellent conductivity. The current-carrying capacity of 1X95mm² is about 180-220A, and that of 1X300mm² can reach 300-350A, meeting the needs of equipment with different powers. The armoured layer provides mechanical protection, resisting underground soil extrusion and stone collision, and is suitable for complex underground environments. Some models (such as Arvfv) may have corrosion resistance to cope with underground moisture and slight corrosion.​ 1X95mm² is suitable for underground branch lines (such as underground distribution branches in residential areas); 1X300mm² is adapted to main lines (such as underground main cables in industrial parks). They are widely used in municipal underground power grids, industrial underground power supply systems, etc., and have become a reliable choice for underground power transmission with stable performance.​
