25kV 200A Bushing Insert threads into a universal bushing well to provide the same function as an integral loadbreak bushing. Using bushing insert makes field installation and replacement possible and efficient. Bushing inserts and elbow connectors comprise the essential components of all loadbreak connections.

Performance
The uncomplicated nature of the current path design delivers superior and reliable performance. An internal broach allows for positive torque controlled installation. Using the optional installation torque tool the bushing insert can be properly tightened into the bushing well without the fear of accidentally breaking the bushing well stud. Power exclusive latch indicator ring, located on the circumference of the bushing’s collar, eliminates the guesswork of loadbreak elbow installation on the bushing insert. The bright yellow ring provides immediate feedback to determine if the elbow is properly installed on the insert. If the yellow ring is completely covered by the loadbreak elbow, it is fully ”latched” if the ring is visible. The elbow can be installed correctly before any problems can occur. The Bushing Inserts are molded with high quality sulfur-cured insulating and semiconducting EPDM rubber.When mated with a comparably rated component, the bushing insert provides a fully shielded and submersible connection for loadbreak operation.
