Distribution Network Operator Approved Cables

DNO-approved cables are crucial components in electrical distribution networks, ensuring the safe and reliable transmission of electricity from power stations to homes and businesses.

Designed and tested for use in the distribution network of electricity. Their primary purpose is to carry electricity from the high-voltage transmission lines to the low-voltage distribution lines that supply power to homes, offices, and industrial facilities.

DNO-approved cables must adhere to strict regulatory standards and specifications set by the relevant electrical regulatory authority in your region. These standards ensure the safety, reliability, and performance of the cables.

What types of cables are included in the DNO-approved range and where can they be used?

The DNO-approved cable range typically includes high-voltage, medium-voltage, and low-voltage cables designed for various applications in electrical distribution networks.

These cables operate across various voltage levels, ensuring efficient power transmission. High-voltage cables connect power generation facilities to substations and interconnect substations within the network. Medium-voltage cables distribute electricity to residential, commercial, and industrial areas, while low-voltage cables deliver power directly to consumers.

Used in overhead lines, underground systems, and substations, DNO-approved cables ensure reliable power distribution across diverse environments. They are essential for maintaining efficient power supply to homes, offices and industrial facilities.

How are DNO-approved cables tested?

DNO cables undergo rigorous testing to meet the electrical, mechanical, and environmental standards set by the relevant electrical regulations and authority in your region.

These tests include voltage endurance, thermal performance, and physical durability. These tests evaluate the ability of the cable to withstand high voltages, how well the cable manages heat and assess their mechanical strength and resistance. The rigorous testing procedures for DNO-approved cables are crucial in verifying compliance with regulatory standards for reliability, safety and performance.

What materials are used in DNO-approved cables?

DNO-approved cables are made from high-quality materials chosen for their durability, connectivity, and insulation properties. These conductors are typically made of copper or aluminium conductors for efficient electrical transmission with minimal loss. Cross-linked polyethylene (XLPE) insulation is commonly used due to its thermal stability and resistance to moisture and chemicals. Additionally, robust outer sheaths made of materials like PVC or polyethylene provide protection shielding the cables from physical and environmental factors such as UV radiation and moisture.
