PVC Split Concentric Cable, XLPE Concentric Cable
BS7870 Cable
Low Voltage (LV) and Medium Voltage (MV) polymeric insulated cables manufactured in accordance with British Standard BS7870 for use by distribution and generation utilities
British Standard BS7870 covers low voltage and medium voltage cables used for the provision of an electricity supply from a distribution main. They are generally buried underground to connect individual houses or commercial properties to the grid bytransmission, distribution and power generation networks. These service cables are not suitable to provide overhead supply.
This Standard applies to concentric and split concentric cables for fixed installations up to and including 19/33kV and is published as a series of parts and sections. Our range ofpower network cables includes those specific to UK DNOs.
