Ground-fault coordination should include MV cable shielding.
Verification of shield performance under ground-fault conditions will prevent systemwide cable damage.As we all know, the metallic shielding in a medium voltage (MV) cable provides the necessary uniform electric field within the cables insulation. What is not as well known is its other equally important function: that of carrying a portion of return ground-fault current.Get Price >>

Shielding Of Power Cables - Electrical Engineering Portal
Why Shielding of cables?Conductor ShieldingInsulation Shielding For Medium-Voltage CablesShielding of Low Voltage CablesMedium and high-voltage power cables, in circuits over 2000 volts, usually have a shield layer of copper or aluminum tape or conducting polymer. If an unshielded insulated cable is in contact with earth or a grounded object, the electrostatic field around the conductor will be concentrated at the contact point, resulting in corona discharge, and eventual destruction of the insulation.As well, leakage current and capacitive cuSee more on electrical-engineering-portalHigh Voltage, Smooth Aluminum Shield/Sheath . - CME WireHigh Voltage Aluminum, Wire and Tape Shield, XLPE Insulation, HDPE Jacket, 69 kV ?C 138 kV; Extra High Voltage Copper, Smooth Aluminum Shield/Sheath, XLPE Insulation, HDPE Jacket, 230 kV; Extra High Voltage Aluminum, Smooth Aluminum Shield/Sheath, XLPE Insulation, HDPE Jacket, 230 kV; Drilmar?

Copper or aluminium? Which one to use and when?
Low Voltage and Medium Voltage CablesTransformersBusbarsThe decision here is which is the lesser of two evils: a greater cable cross-section or a higher cable weight? Generally speaking, aluminium cable will be substantially cheaper. However, it is still worth recalling that copper cable is more ductile and less susceptible to electrical contact problems and thus offers a greater margin of safety than a corresponding aluminium cable. Due to its smaller cross-section, the copper cable will aSee more on electrical-engineering-portalRod , SouthwireHigh Voltage Underground Transmission Cable Systems. HVAC. Industrial Products.
