Product Description

Beida is a professional supplier of cables and wires in China. In terms of product structure, our BS 6724 Power Cable uses cross-linked polyethylene (XLPE) insulation and a halogen-free, low-smoke polyolefin sheath, combined with a galvanized steel wire armor layer, forming a multi-layered protection system. The halogen-free, low-smoke sheath has significant safety advantages; when exposed to fire, it not only releases extremely low amounts of smoke, reducing the impact of smoke on ambient light transmission and ensuring escape visibility, but also produces non-toxic and non-corrosive smoke, preventing secondary injuries and fully meeting the safety needs of densely populated areas.

The cables are available in a variety of specifications, from single-core to 48-core. The conductors are made of high-quality annealed copper, offering excellent conductivity. The insulation layer boasts high insulation strength and has undergone withstand voltage testing to ensure safe operation. Whether for power transmission in industrial plants, wiring in high-rise buildings, or power distribution in underground pipelines, Tianjin Beida BS 5467 power cables provide reliable solutions, building a solid safety barrier for power transmission with professional quality.
