Shielding layer In order to uniformly conductive core and insulated electric field, medium and high voltage power cables of 6kV and above generally have a conductor shielding layer and an insulating shielding layer, and some low voltage cables are not provided with a shielding layer.
Description of Problems in the Construction of Power Cables1 Eddy Current Problem caused by High Current Power CableIn the construction of power cables, steel brackets are used, steel protection tubes are used, and cable cards and overhead laying are used. Any steel (iron) closed loop formed around the power cables may form eddy currents. E...
