Low-Smoke Zero-Halogen Flame-Retardant & Fire-Resistant Cable

Low Smoke Zero Halogen Flame Retardant & Fire Resistant Cable

Conductor: Rare earth aluminum alloy Insulation: Fire resistant mica tape, flame retardant silane cross-linked polyethylene

Bedding: Flame retardant fiberglass tape Armour: Aluminum alloy strip interlocked armour

Sheath: Polyolefin sheath。

This cable overcomes defects of conventional aluminum core cables and offers advantages superior to copper cables. It features high flexibility with a bending radius of only 7 times the outer diameter. Adopting advanced compacting technology, the compaction factor reaches 0.93. The metal interlocked armour structure reduces fire hazard. It can withstand flame exposure at 750–800 ℃ for 40 minutes without propagation of flame or dripping, and maintains power supply. It meets Flame Retardant Class I A and Fire Resistant Class I standards. The cable provides longer service life and complies with national energy conservation and environmental protection requirements.

Product Introduction
