Power network and local distribution cables form the critical infrastructure that delivers electricity from generating stations through transmission networks to the final connection at residential, commercial, and industrial properties. These cables operate across multiple voltage levels: Low Voltage (LV) up to 1kV for final distribution, Medium Voltage (MV) at 6.35/11kV and 12.7/22kV for primary distribution, and High Voltage (HV) at 19/33kV for sub-transmission. In the UK, these cables must be approved by Distribution Network Operators (DNOs)—the regional companies responsible for operating the electricity distribution network from the National Grid to end users. The primary standard is BS 7870, which specifies cables for power distribution at voltages up to 36kV.

DNO-Approved Cables are electrical cables that have been certified and approved by UK Distribution Network Operators (DNOs) for use in electricity distribution networks. DNOs are the companies responsible for operating and maintaining the electricity distribution infrastructure that delivers power from the national transmission network to homes and businesses. These cables must meet stringent technical specifications and undergo rigorous testing to ensure reliability, safety, and compatibility with the existing grid infrastructure.

British Standard BS7870 Part 3 covers low voltage cables used for the provision of an electricity supply from a distribution main. These cables are manufactured in accordance with BS7870 Parts 3.11, 3.12, 3.20, and 3.22 for use by distribution and generation utilities. They are generally buried underground to connect individual houses or commercial properties to the grid by transmission, distribution, and power generation networks.
