Live Front Bushing
Live front bushings comprise porcelain spade bushings with exposed conductor connectors at the top. Bushings have either tin-plated copper alloy clamp-type connectors or four- hole and three-hole spade terminal, both arranged for a vertical take-off. For 34.5kV and below pad-mounted transformers, the clamp connectors accommodate No. 6 AWG solid to 250 kemil stranded conductors. The holes in the spade terminal are on the same plane, with a typical diameter of 14.3 ± 0.8 mm and a center-to-center distance of 44.5 ± 0.8 mm. Installed on the high-voltage side of live front pad-mounted transformers, cable termination is achieved using mechanical lugs or clamp plugs, providing a secure connection. Live front bushings are available in voltage ratings of 15 kV, 25 kV, 34 kV, and 44 kV.
