High Hardness LSFH
All or part of the insulation layer, sheath, outer sheath, and auxiliary materials (taping and filling) of halogen-free low-smoke flame-retardant cables are halogen-free cross-linked polyethylene (XLPE) flame-retardant materials, not only Has better flame retardant properties, and no halogen acid gas is released when the cable is burned.
The smoke generation of the cable is also small, and the corrosive gas generated by the combustion of the cable is also a compromise between the flame retardancy and the reduction of the halogen acid gas generation. The low-halogen low-smoke flame-retardant cable is developed. Its halogen content is about 1/3 of that of halogen-containing flame retardant cables. Smoke production is also close to accepted “low smoke” levels
