Main Advantages

1. Stable low-voltage withstand for engineering main power distribution systems Rated at 0.6/1kV, this product is fully compatible with low-voltage power frequency main distribution systems for industrial plants, commercial buildings, residential communities and municipal projects. It meets high-standard engineering requirements including high-power power transmission, centralized equipment power supply, outdoor pipe network and underground buried power distribution. It features balanced and stable insulation voltage resistance, with low risks of insulation breakdown, electric leakage and voltage attenuation under long-term full-load operation. It can continuously and stably carry power loads of large equipment, suitable for long-distance and heavy-load low-voltage main power distribution projects.
2. Armoured mechanical protection with outstanding compression and damage resistance Equipped with steel tape armour structure, the cable delivers excellent compression resistance, tensile resistance, impact resistance and rolling resistance compared with ordinary non-armoured cables. It effectively protects against soil and stone extrusion, mechanical collision and puncture damage during underground direct burial, avoiding hidden dangers such as cable deformation and insulation damage. It greatly improves circuit safety for underground laying, pipe gallery installation and road crossing conduit routing, adapting to complex civil construction environments.
3. Corrosion and weathering resistance for longer service life in underground conditions It adopts high-performance XLPE cross-linked polyethylene insulation and flame-retardant PVC outer sheath, together with enclosed armoured protection structure, featuring excellent moisture & waterproof performance, corrosion resistance, oxidation resistance and underground temperature ageing resistance. It can withstand harsh underground conditions such as humid ponding, acid-alkali soil and alternating seasonal temperature changes. When buried underground for long periods, it resists corrosion, sheath cracking, insulation failure and core wire oxidation, reducing failure rate of buried lines and cutting high costs of excavation, maintenance and replacement of underground cables.
4. ZC-class flame retardant protection for high fire safety level in engineering The whole cable adopts ZC flame-retardant formulated material with excellent self-extinguishing and fire suppression capability. It hardly sustains flame propagation upon open fire exposure and effectively restrains cascading fire spread along cables. For densely laid cables, enclosed pipe gallery installation and concentrated wiring in power distribution rooms, it prevents fire spreading across the whole pipe network and distribution system triggered by a single cable ignition, complying with fire protection codes for key municipal, industrial and civil projects.
5. Stable electrical performance with low power transmission loss under heavy load Constructed with stranded high-purity aluminium conductors, it boasts good conductivity, uniform resistance, low temperature rise when energized and low transmission loss, together with sufficient and stable current-carrying capacity to continuously bear heavy industrial and civil power loads. The dense cross-linked insulation layer features stable voltage resistance and good sealing, with outstanding leakage prevention, breakdown resistance, moisture and waterproof performance, ensuring 24-hour uninterrupted and stable high-load operation of underground main power distribution systems.
