Abstract
High Voltage Direct Current (HVDC) cable has the ability of transmitting electrical energy over long distances in an economical way, with improved stability and reliability. HVDC Cable also provides a compact and low-loss transmission power line, in comparison with the conventional cable made out of copper or aluminium. The design of insulation for HVDC extruded cables is one of the most challenging issues, mainly due to the dependence of its dielectric properties on temperature, electric field distortion due to accumulation of space charge in the insulation. However, there is a great potential for development of extruded HVDC cables globally. This paper reviews the development of HVDC cable for electrical power transmission around the world, new materials for HVDC extruded cables, issues with space charges,methods for measurement of space charges and qualification tests on HVDC cables.
