Flame Retardant XLPE Insulated Power Cable is designed for power transmission and distribution systems rated up to 0.6/1kV. It adopts cross-linked polyethylene (XLPE) as insulation, providing superior electrical performance, high heat resistance, and excellent mechanical strength. The outer sheath is made of flame-retardant PVC or LSZH (Low Smoke Zero Halogen) material, effectively limiting flame spread and smoke emission in the event of fire. This cable is ideal for use in high-rise buildings, subways, tunnels, petrochemical plants, power stations, and other fire safety-critical areas.
