BS7889 Cable

BS7889 is the British Standard for thermosetting insulated, non-armoured cables for fixed installations.

Typically with a voltage rating of 600/1000V. These single or multi-core cables feature XLPE (cross-linked polyethylene) insulation and a PVC (polyvinyl chloride) sheath, suitable for use in industrial areas and buildings where mechanical damage is not a primary concern. 

They are not designed for direct burial but can be installed on cable trays, in conduit, or embedded in plaster.

Widely used in power and lighting applications within industrial buildings and general construction, can be surface mounted and also suitable for installation inside conduits and trunking. This cable type can also be embedded in plaster.

What it is NOT for
Not intended for direct burial in the ground.
High mechanical risk areas: The non-armoured construction makes it unsuitable for areas with a high risk of mechanical damage.
