Bushing wells are utilized for 200 amp loadbreak interfaces. Bushing wells are typically designed for compatibility with multiple voltage classes such as 15kV, 25kV, and 35kV. For this reason, a single 35kV rating is common since it allows the same well to be used with inserts of differing ratings-such as 15kV, 25kV, and 35kV. The well fits into a hole in the transformer front plate-just large enough for the shank to pass through, but small enough to allow the wider rim of its collar to rest against the exterior tank wall with a gasket seal between the two surfaces.
The middle of the well houses the conductor, a copper ⅜"-16 threaded stud, which provides a termination point for the winding leads of the transformer on one end, and a threaded insert on the other. The stud is designed to withstand a minimum torque of 17 ft. lbs without breaking or stripping per IEEE Std 386. The copper stud can be either fixed or removable. The removable version allows for easy replacement if breakage occurs in the field.
