What is a flame retardant wire?

1. What is a flame retardant wire? Flame-retardant wire means that when a fire accident occurs, it can stop and delay the spread and extension of flame along the wire, and minimize the expansion of wire fire scope. But also has the characteristic of self-extinguishing after a fire. It can also be understood that when wires and wire products catch fire due to their own or external heat sources, the wires will not continue to burn or temporarily burn after the fire source subsides.

2. The structure of flame-retardant wires is basically the same as that of ordinary wires, except that the insulation layer, sheath, outer sheath and auxiliary materials (wrapping and filling) are all or part of flame-retardant materials. Flame-retardant wires are suitable for fixed laying on transmission and distribution lines with AC 50Hz and voltage level of 1kV or below, and are mainly used in places with high flame retardant requirements, such as hotels, banks, hospitals, factories, commercial and residential integrated wiring, etc.
