How does wire shielding work
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… WebThese are some of the most popular options that we have available that would provide a solution for RFI projects: 70 Holes Per Inch – 0.22mm Hole. Metal – 304 Stainless Steel. Holes / Wires Per Linear Inch = 70. Holes / Wires Per Square Inch = 4,900. Wire Thickness = 0.14mm. Hole Size / Aperture = 0.223mm.
