Analysis of Wire and Cable Fires

Oxidation, looseness and poor contact of cables increase electrical resistance and provoke overheat or strike fire, becoming the reason of most fires in modern high buildings, especially modern intelligent buildings that own thousands of wire and cable contacts. After a long-time operation of electric and electronic equipment, wires and cables will be heated up and accelerate the aging or damage of wire joining and insulation layer, which greatly increase the possibility of fire accidents provoked by overheat. Another reason for fire accidents in wire and cable is human factor.

 

Flame retardant materials are widely applied in wires and cables to make fire self-extinguish or slow down the fire spread. Flame retardants do not affect the wire performance, physical performance and mechanical performance, and thus the addition of flame retardants to insulation layers can form an effective protective layer.
