The grounding elbow is the preferred equipment for underground power system operation procedures. It can provide grounding leads for cable maintenance and lead wires for cable experiments. The grounding elbow can be used alone or combined with the single or double-pass bushings of box-type transformers and ring main units to form a visible cable grounding point. The grounding elbow is made of a copper conductive rod with arc extinguishing, a copper crimped joint, and cast with high insulation strength and anti-aging insulating rubber. It is a fully insulated product, with a grounding cable of about one meter at the lower end. The outer insulation strength of the grounding elbow is , and it is elevated when used for equipment testing.
