Application：
It is suitable for power transmission of power equipment in indoor, tunnel, cable trench, bridge, pipeline and direct buried environment, indoor, tunnel, cable trench, or buried laying, etc., in AC 50Hz, rated voltage 6kV ~ 35kV power transmission and distribution lines, the main function is to transport electric energy. Can withstand a certain mechanical external force, but can not withstand large tension, single-core cable is not allowed to lay in the magnetic pipeline, flame retardant cable has the function of preventing the spread of fire in the cable circuit, can avoid the expansion of fire accidents to reduce losses, suitable for subway, tunnel, high-rise buildings and other cable laying dense places.
