Main Advantages

1. High voltage withstand rating, compatible with 15kV medium & high voltage transmission systems Rated at 8.7/15kV, this product is suitable for medium and high voltage power systems including main transmission lines of urban power grids, high-voltage distribution in industrial parks, outgoing cables of PV and wind power booster stations, and high-voltage power supply for mines. It fully meets strict requirements for high-voltage transmission, long-distance power delivery and large-capacity load supply in large-scale projects. Featuring uniform and stable insulation withstand voltage and sufficient insulation margin, it is less prone to insulation breakdown, partial discharge and voltage attenuation under long-term high-voltage operation. It ensures safe, stable and continuous power supply of high-voltage transmission lines and fits various key medium & high-voltage power engineering projects.
2. Reinforced armoured mechanical protection with outstanding compression and damage resistance The cable adopts high-quality steel tape armour with inner and outer double-layer sheaths. Compared with ordinary high-voltage cables, it delivers excellent resistance against extrusion, impact, crushing and tensile force. It effectively protects against external damage such as heavy soil & stone pressure, mechanical collision during construction, compression caused by foundation settlement and piercing by hard objects in direct underground burial. It prevents power outage, electric leakage and breakdown accidents triggered by mechanical damage to high-voltage lines, greatly improving safety and stability of cables laid underground, in pipe galleries and tunnels.
3. Corrosion and weathering resistance for harsh outdoor and buried working conditions Constructed with high-performance XLPE cross-linked polyethylene insulation and flame-retardant weather-resistant outer sheath together with sealed armoured protection system, it boasts excellent high & low temperature resistance, anti-ageing, anti-oxidation, moisture & waterproof performance and acid-alkali corrosion resistance. It can withstand harsh complex environments such as outdoor exposure to sunlight and rain, alternating seasonal temperature changes, underground ponding and saline-alkali soil corrosion. It resists cracking, sheath peeling and insulation ageing failure after long-term laying, greatly extending the service life of high-voltage cables and reducing power grid operation, maintenance and cable replacement costs.
4. ZC-class flame retardant protection with superior fire safety for high-voltage projects The whole cable is manufactured with specially formulated ZC flame-retardant material and meets flame retardancy standards. It features excellent self-extinguishing and fire suppression performance to restrain flame spread. In scenarios of densely laid cables, enclosed high-voltage pipe galleries and concentrated wiring in substations, it effectively stops fire spreading along high-voltage lines. It avoids large-scale power grid paralysis and equipment damage caused by ignition of a single cable section, fully complying with fire safety specifications for municipal high-voltage power grids, industrial high-voltage distribution and new energy booster stations.
5. Stable electrical performance and low transmission loss under heavy high-voltage loads Made of finely stranded high-purity aluminium conductors, it has good conductivity, uniform resistance and low transmission loss. It generates low temperature rise under full high-voltage load and provides stable and sufficient current-carrying capacity to continuously carry large-capacity high-voltage loads of power grids and industries. The high-voltage dedicated XLPE insulation layer features ultra-high dielectric strength, good sealing and uniform electric field distribution, with outstanding resistance to partial discharge, leakage and high-voltage breakdown. It guarantees 24-hour uninterrupted, highly safe and precise stable operation of medium & high voltage power transmission systems.
