APPLICATION

This 300/500V single core power cable is manufactured in accordance with BS 7211 and identified as BS Code 6241B. It features a cross-linked polyethylene (XLPE) insulated core and a low smoke zero halogen (LSZH) sheath, offering excellent thermal stability, fire performance, and electrical reliability. Widely used in power stations, underground passenger systems, airports, hotels, hospitals, high-rise buildings, and petrochemical facilities, it is ideal for applications where flame retardancy and low toxicity are essential. The cable is suitable for fixed wiring in dry or damp environments, especially where people safety and environmental protection are a concern..
