Procedural Steps: CAUTION To prevent damage to the equipment ensure that this repair is sufficiently insulated to prevent the center conductor from shorting to the shield. 1. Remove 1/2-inch of insulation from the shielding and join the severed ends of the shielding together by wrapping a conductive material over the repair. Some suitable materials are tubular copper braid, metal gauze, conductive foil from .gum wrappers. cigarette packages or common kitchen foil. 2. Wrap the entire repaired area with electrical tape. 3.
