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.

Fixed wiring cables are the backbone of electrical installations in buildings, designed to be permanently installed in fixed positions—fastened to supports, laid in conduits, or embedded in building structures. Unlike flexible cables used for portable equipment, fixed wiring cables power the essential infrastructure of residential, commercial, and industrial environments: sockets, switches, lighting circuits, distribution boards, and fixed appliances. These cables must comply with the Construction Products Regulation (CPR) for use across Europe, requiring specific fire performance classifications from Aca (highest) to Fca (lowest). The primary choice in fixed wiring is between PVC sheathed cables (economical, general use) and LSZH (Low Smoke Zero Halogen) cables that provide enhanced safety in fire situations by minimizing toxic smoke and corrosive gases.

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.
