The insulation material of the cable is non-halogen cross-linked Polyolefin compound. It is good flame-retardant and fire resistant. When a fire occurs, the cable prevents fire spreading. Even if the cable were ignited, it would not emit toxic halogenous gas. It's safer, more reliable and less harmful to environment than PVC insulated cables. The cable is widely used in high rises, subway, nuclear power station and large public buildings.
