Earth Continuity Cable (ECC) for EHV Cables

Single-core cables are the most commonly used cables for underground high-voltage transmission systems. This is because 3-core high-voltage transmission cables, mainly above 33kV, are not easily transportable due to their very thick insulation and weight. A single-core cable is lighter than a three-phase or 3-core cable. The insulation of these single-core cables is covered with … Read more
