Exploring EHV Cables and Their Applications
Ideally, extra high voltage (EHV) cables are designed to handle extremely high voltages. This voltage range typically begins at 66 kV and can exceed 220 kV, with some applications extending up to 400 kV. The goal is to transmit large amounts of power with minimal losses. Most EHV cables use copper or aluminum conductors. The commonly preferred insulation material for these cables is XLPE, thanks to its excellent electrical properties and high thermal resistance. Applications of EHV Cables Power transmission and distribution utilities: EHV cables are used to carry large amounts of power from where it is generated to substations located over long distances. In simple words, from power plants to substations. Also, these cables help distribute electricity from substations to various sectors like industrial, commercial, and residential areas. Mining and processing industries: EHV cables are ideal for the power requirements of mining operations of critical minerals. They also make a pe...
