Flame-retardant Cable with Oxygen-separation Layer

Detailed Product Description

The Application of Cable

It is used in places with high demand on flame-proof such as high-rise building, oilfield, power station, mine, subway, control & supervision loop and computor system. Through development & application of oxygen-seperation technology, a kind of colloid inorganic metallic compound which is nontoxic, smell-less and without halogen is hilled between insulation and outer sheath. When the cable is burning, the original soft metallic compund heated and discomposed, released the eduction of crystallized water, absorbed much heat, thus reducing the temperature of outer combustible and surrounding environment. That makes the burning cable self-extinct
