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 BS 7835 specifies requirements for single-core and three-core armoured cables with thermosetting insulation rated from 3.8/6.6kV up to 19/33kV. These cables are engineered with Low Smoke Zero Halogen (LSZH) sheathing, designed to produce significantly reduced levels of smoke and corrosive gases when exposed to fire compared to conventional cables specified under BS 6622.
