RHH/RHW/RHW-2 |
Low smoke, non-halogen and flame-retardant cable |
Description of the pure
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 spreg. 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.
