PURPOSE:To simplify complicated works by laying a insulated wire at the inner surface of a synthetic resin earthing lace in the longitudinal direction in its full length and by covering and supporting this insulated wire with a covering extrusion-molded as integral to the earthing lace. CONSTITUTION:An insulated wire 1 is laid at the center of an earthing lace with an arc-shaped cross-section in its full length, and covered with a synthetic resin, and this covering 2 is provided with a slit over its full length. For example, the earthing lace cut to about 3.3m long, is prepared, and, in the site, the insulated wire 1 is connected to an earthing wire led down from a distribution system in a position higher than a level where parssers by can touch, and its joint is insulated. Then, the earthing lace M, while applied onto the surface of a mast, is secured by steel bands, and the lower end of the insulated wire 1 is connected to an earthing rod. |
