6381B cable is an XLPE insulated and LSZH sheathed low voltage cable for power networks and protected electrical installations.
It is suitable for transmission and distribution support systems, substations, power stations, rail transit, airports, industrial facilities and infrastructure projects.
The cable is designed for installations where low smoke zero halogen sheath performance is required to reduce smoke emission and corrosive gas release in the event of fire.
Typical applications include low voltage power distribution, electrical cabinets, switchgear, control equipment, building services and protected cable routes.
The XLPE insulation provides reliable electrical performance, while the LSZH sheath supports safer installation in public buildings, transport systems and critical infrastructure.
The cable should be selected according to voltage rating, conductor size, conductor class, installation method, sheath colour, fire performance requirement and project specification.

FAQ
What is 6381B cable used for?
6381B cable is used for low voltage power distribution, substations, infrastructure projects, switchgear, electrical cabinets and protected cable routes.
Is 6381B an LSZH cable?
Yes. 6381B uses an LSZH / LSOH outer sheath to reduce smoke emission and corrosive gas release in the event of fire.
The insulation is XLPE, not LSZH.
What is the difference between 6381B and 6381Y?
6381B is XLPE insulated and LSZH sheathed.
6381Y is PVC insulated and PVC sheathed.
What standards does 6381B cable follow?
6381B cable is commonly supplied according to BS7211 and IEC 60502 requirements.
Can BURYCABLE supply 6381B cable?
Yes. BURYCABLE can supply 6381B cable according to project size, voltage, conductor size, sheath colour, length and packing requirements.
