WebDec 16, 2024 · If devices are unreferenced or floating in regard to each other (say both are battery operated handheld devices), the shield must be connected on both ends to create a single ground connection between them. When only one end connects to shield, it is usually the transmitter side. Medium and high-voltage power cables, in circuits over 2000 volts, usually have a shield layer of copper or aluminium 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. Leakage current and capacitive current through the insulation presents a danger of electrical shock. The gr… Web(1) Shielding the inside from the outside.
