Expansion Busbar Support Coupler with Baseplate

Designed to support a busbar on a post insulator of a substation's primary equipment. The expansion connector allows the connector to expand and contract between the fixed points in response to changes in operating temperature, a short-circuit, or seismic events. In doing so, the angular movable expansion joint helps to reduce bending stress on apparatus terminals enhancing reliability and lifetime. Expansion connectors are available with different mechanical bearing technology as well as welded or bolted attachment to tubes. Additional sizes are available upon request. The base plate configuration is specified at the time of order. Additional sizes are available upon request. Consult PLP for additional details.
