Main Advantages

1. Ultra-high voltage resistance, suitable for 15kV medium and high-voltage power transmission systems Rated at 8.7/15kV, this product is perfectly adapted to medium and high-voltage transmission systems including urban main power grids, industrial high-voltage distribution, photovoltaic and wind power booster stations, industrial and mining enterprises’ high-voltage power supply, and key municipal power projects. It fully meets strict engineering standards for long-distance high-voltage power transmission, large-capacity load delivery and centralized power supply for large-scale equipment. The cable features sufficient high-voltage insulation margin and uniform electric field distribution. No partial discharge, insulation breakdown or voltage attenuation occurs under long-term full-load high-voltage operation. It delivers excellent power supply stability and comprehensively guarantees the safe and continuous operation of medium & high-voltage power grids and industrial power systems.
2. Reinforced protection with steel tape armour, outstanding mechanical damage resistance Adopting a hermetically sealed high-quality steel tape armour structure and double sheath protection system, it boasts superior resistance to crushing, impact, extrusion, puncture and tension compared with ordinary high-voltage cables. It effectively protects against external damages such as heavy earth and rock pressure during direct underground burial, compression caused by foundation settlement, mechanical collision and piercing by hard objects. It eliminates leakage, breakdown and power outages induced by mechanical damage to high-voltage cables, greatly improving the line safety factor for complex laying conditions such as cable tunnels, enclosed pipe galleries, deep burial in wild areas and conduit crossing roadbeds.
3. Weather resistance, corrosion resistance and anti-ageing performance for harsh outdoor and buried working conditions It adopts high-voltage dedicated XLPE cross-linked polyethylene insulation paired with flame-retardant weather-resistant outer sheath together with enclosed armoured protection. The compact and stable material structure offers excellent high & low temperature resistance, ozone resistance, oxidation resistance, moisture & waterproof performance and acid & alkali corrosion resistance. It can withstand harsh environments such as strong outdoor sunlight exposure, wind and rain erosion, alternating seasonal temperature changes, as well as underground ponding, saline-alkali corrosion and underground temperature ageing. It resists cracking, sheath peeling, insulation failure and core conductor oxidation during long-term laying, greatly extending the service life of high-voltage cables and cutting operation, maintenance and reconstruction costs of high-voltage power grids.
4. ZC-class flame retardant protection, top fire safety level for high-voltage engineering The whole cable adopts special ZC flame-retardant formulated material meeting flame retardancy standards, with excellent self-extinguishing and fire suppression capacity to restrict flame spread. For high-risk scenarios including enclosed spaces of high-voltage pipe galleries, concentrated wiring in substations and densely laid cables, it effectively blocks fire propagation along cable lines. It prevents large-scale grid paralysis and equipment damage triggered by faults in a single cable section, fully complying with fire protection specifications for municipal high-voltage power grids, new energy booster stations and industrial high-voltage distribution projects.
5. High-conductivity solid copper with low loss, excellent performance for high-voltage heavy-load power transmission Constructed with finely stranded high-purity oxygen-free copper conductors, its conductivity far exceeds that of aluminium cables. It features uniform and stable resistance, extremely low temperature rise under high-voltage operation and low transmission loss, with sufficient and stable current-carrying capacity. It can continuously bear ultra-large-capacity high-voltage loads of power grids, new energy power stations and large industrial equipment. The high-voltage dedicated cross-linked insulation layer has high dielectric strength, good sealing and stable voltage resistance, with outstanding performance against partial discharge, electric leakage and high-voltage breakdown. It ensures 24-hour high-precision, high-safety and trouble-free stable operation of medium & high-voltage power transmission systems.
