Low
smoke, non-halogen and flame-retardant cable

Description of the purpose
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.
