GWH fire retardant sleeve can be used for fire protection of power and telecommunication cables. It is of great significance to eliminate hidden dangers and ensure the normal operation of transmission and distribution and telecommunication lines. GWH fireproof and flame retardant sleeve is a new product for power and telecommunication cables. It has the advantages of flame retardancy, insulation and operability. It uses low smoke and halogen-free, and does not affect the cable ampacity during cable operation. As the GWH fire-retardant sleeve is used to wrap on the surface of the cable sheath, when a fire occurs, it can quickly form an oxygen resistant and heat-insulating carbonized layer, effectively preventing the burning of the cable. GWH fire retardant sleeve can be widely used in high and low voltage power supply lines, especially for cable fire protection in substations, subways, tunnels, chemical industry, coal mines, large buildings and other environments, and can also be applied to other parts with fire protection requirements.
