Main Advantages

1. Stable low-voltage withstand for engineering heavy-load power distribution systems Rated at 0.6/1kV, this product is fully compatible with low-voltage power frequency heavy-load distribution systems for civil buildings, commercial parks, industrial plants and municipal projects. It meets high-standard power demands including high-power equipment power supply, main floor power distribution, outdoor pipe network power distribution and centralized power supply for underground works. Featuring balanced and stable insulation voltage resistance and sufficient insulation margin, together with excellent conductivity of copper core, it is less likely to suffer insulation breakdown, electric leakage, voltage attenuation and unstable power supply under long-term full-load operation. It can continuously and steadily bear heavy equipment loads and is suitable for various large and medium-sized low-voltage underground buried and pipe network power distribution projects.
2. Steel tape armoured protection with powerful mechanical damage resistance Built-in high-quality steel tape armour structure, the cable boasts outstanding resistance to extrusion, crushing, impact, puncture and tension compared with ordinary non-armoured cables. It effectively defends against external damages such as heavy soil and stone pressure, compression from foundation settlement, mechanical collision during construction and piercing by hard objects under direct underground burial. It eliminates hidden dangers including cable compression deformation, insulation damage and core wire breakage, greatly improving line safety and anti-damage performance for laying conditions such as underground direct burial, cable tunnels, enclosed pipe galleries and conduit crossing roadbeds.
3. Corrosion and weathering resistance & anti-ageing for longer service life in buried conditions It adopts high-performance XLPE cross-linked polyethylene insulation and flame-retardant weather-resistant PVC outer sheath, together with a sealed armoured protection system. Its compact and stable material structure delivers excellent moisture & waterproof performance, corrosion resistance, oxidation resistance, high & low temperature resistance and underground temperature ageing resistance. It can withstand harsh complex working environments such as underground ponding, acid-alkali and saline-alkali soil, alternating seasonal temperature changes and outdoor exposure to sunlight and rain. When buried underground for long periods, it resists cracking, sheath peeling, corrosive ageing and insulation failure, greatly reducing the failure rate of underground lines, extending cable service life and cutting costs of excavation, maintenance and replacement in later engineering stages.
4. ZC-class flame retardant protection with high fire safety level for engineering The whole cable adopts ZC flame-retardant environmentally friendly formulated material that meets flame retardancy standards, featuring excellent self-extinguishing and fire suppression capability to restrain flame propagation. In high-risk enclosed scenarios such as densely laid cables, underground closed pipe galleries and concentrated wiring in power distribution rooms, it effectively blocks fire spread along cable lines. It prevents large-area power outage and flame propagation across the whole pipe network triggered by short-circuit ignition of a single cable section, fully complying with fire protection specifications for key industrial, commercial, municipal and residential projects.
5. High-conductivity solid copper with low loss and stable heavy-load power transmission Constructed with finely stranded high-purity oxygen-free copper conductors, it has superior conductivity, uniform resistance, low temperature rise when energized and ultra-low transmission loss, with sufficient and stable current-carrying capacity to continuously carry high-power heavy dynamic loads for industry and civil use. The cross-linked insulation layer features high dielectric strength, good sealing and stable voltage resistance, with outstanding moisture-proof, waterproof, leakage-proof and breakdown-resistant performance. It ensures 24-hour uninterrupted, high-load and high-precision stable operation of underground main power distribution systems.
