6381B cable is an XLPE insulated and LSZH sheathed single core cable for low voltage power supply and protected fixed wiring applications.
It is commonly used in telecom DC power supply systems, equipment rooms, power distribution cabinets, switchgear and control equipment.
The cable is suitable for installations where low smoke zero halogen sheath performance is required.
Typical applications include telecom facilities, building services, plant rooms, electrical cabinets, DC power supplies and protected cable routes.
The XLPE insulation provides reliable electrical performance, while the LSZH sheath helps reduce smoke emission and corrosive gas release in the event of fire.
The flexible copper conductor construction supports easier installation in cabinets, equipment rooms and confined cable routes.
6381B cable should be selected according to voltage rating, conductor size, conductor class, installation method, sheath colour and project specification.
