The Insulated Standoff Bushing is designed to be installed in the parking stand mounted on a transformer or other apparatus. It is used together with the cable accessories such as elbow connector, elbow surge arrester and the other 600A Loadbreak Accessories. A grounding lug is provided on the standoff bushing bracket for attachment of a drain wire to ensure dead front construction. When mated with a comparably rated product, the insulated standoff bushing provides a fullyshielded, submersible, separable connector for energized operation. The standard insulated standoff bushing has a stainless steel eyebolt with a btass pressure foot. The molded EPDM rubber body is bolted to a stainless steel base bracket using a galvanized steel holddown ring.
