The insulation and sheath of wire and cable are usually made of plastic or rubber, which is flammable. When the cable is overloaded, short-circuit, partial overheating and other fault, and under the action of external heat, it will cause burning, resulting in fire accidents.
Fire Testing to
Cable & Wire
In order to reduce and avoid fire accidents of cable and wire, the requirement of fire performance of cable and wire is stringent. Fire testing to cable and wire generally includes single burning, bunch burning, smoke density, smoke toxicity and so on.
