Characteristics & Applications
Â
The main feature of the flame retardant XLPE power cable is hard to get fire or that the continous burning of cables is vert limited when it is on fire. It applies to the places with many cable is laid tightly together such as power-generated station, subway, tunnel, hight-storey building, large-sized factory and mines, oil field and coal mine.
