BS7870-4.10 Cable

Medium Voltage (MV) polymeric insulated cables manufactured in accordance with the British Standards Institute and conforming to the British Standard BS7870-4.10. Specifically designed for use by distribution and generation utilities industry sectors.

to BS7870-4.10 Cable datasheets

British Standard BS7870-4.10 covers Copper and Aluminium medium voltage cables used for the foundation of electricity supply from a distribution main. As medium voltage polymeric insulated cables, these distribution and power network cables are approved and supplied in various sizes for utility grid networks worldwide.

BS7870-4.10 Cable Specification & Application

Cables in accordance with BS7870 Part 4 are designed to connect sub-mains to local networks where the final connection occurs. They can be installed either by direct burial in the ground or in buried cable ducts - it is important to note these service cables are not suitable to provide overhead transmission supply (please refer to overhead line or aerial bundle cables for potential suitable products).

BS7870-4.10 Single Core / BS7870-4.20 Three Core

BS7870 part 4.10 cable standard applies to single core cables up to 19/33kV, with BS7870 4.20 relating to 3-core cables rated at 11kV. Whilst the standard permits XLPE (Cross-linked Polyethene) or EPR (Ethylene Propylene Rubber) insulation material, it is more common to see XLPE in use.

The Distribution Network Operators (DNOs) who operate the UK electricity distribution system have their own cables manufactured generally in accordance with BS7870-4.10 but it should be noted that the metallic screen cross-sectional area and material thicknesses are bespoke to their specifications.

BS7870-4:10 Cable construction

BS7870 Part 4, section 4.10 covers single core cables for distribution utilities with extruded insulation up to and including 11kV and 33kV. The 11kV cables are often supplied and installed in triplex formation.

Technical support BS7870-4.10

Whether it is for contestable works on national grids, or private medium voltage networks, our technical team can support specification and procurement to ensure the best fit cable for the application and installation. Electrical data is provided on the attached datasheets but should you require additional information, please discuss with the team.

For reference, BS7870 Part 3 references Low Voltage single core distribution cables up to 0.6/1kV, with the concentric & split concentric cables for the final domestic connection falling under this standard. Support with specification with these cables is also available.
