General
15kV 200A Bushing insert threads into a universal bushing well to provide the same function as an integral load break bushing. Using bushing inserts makes field installation and replacement possible and efficient. Bushing inserts and elbow connectors comprise the essential components of all load break connections. The bushing Insert uses a patented wholly current path, containing only one current transfer point, within the insert itself. The uncomplicated nature of the current path design delivers superior, 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 load break elbow installation of the bushing insert.
The bright yellow ring provides immediate feedback to determine if the elbow is properly installed on the insert.
The Bushing Insert are molded using high quality sulfur-sured insulation and semiconduction EPDM rubber. When mated with a comparably rated component, the bushing insert provides a fully shielded and submersible connection for load break operation.

Product structure
1、INSULATION: High quality, peroxide-cured EPDM rubber formulated, mixed and molded inhouse for consistent and reliable field performance.
2、LATCH INDICATOR RING: Molded-in bright yellow ring eliminates elbow installation guesswork by assuring a quality connection.
3、SEMI-CONDUCTIVE SHIELD: High quality EPDM rubber provides protective dead front shield that make sure they have grounding
4、THREADED BASE: 3/8"-16 UNC Copper threads provide connection to bushing well stud.
5、HEX BROACH: 5/16" hex broach permits consistent installation with torque tool.
6、INTEGRAL PISTON-CONTACT: One-piece copper component provides a multi-point, knurled current transfer to the contact holder, During a" fault-close”switching operation, the piston is forced quickly forward to engage the elbow\s load break probe.
7、ARC SNUFFER ASSEMBLY: Arc-ablative plastic produces arc extinguishing gas during load break switching operations.
