Removable Stud Replacement Kit

The Cooper Power Systems 200 A 15, 25 and 28 kV Class Bushing Well meets the full requirements of the latest revision of IEEE Std 386 standard — separable insulated connector systems. It is designed for the termination of primary winding leads at the front plate of fluid-filled apparatus rated at either 8.3/14.4 kV, 15.2/26.3 kV or 16.2/28.0 kV (for Canadian applications). The bushing well is externally clamped for sidewall mounting on single- or three-phase transformers filled with transformer oil or an approved equivalent bio-based fluid. It is available for a 2.56 inch (65 mm) hole and mates with all bushing inserts meeting applicable IEEE Standards. The knurled copper stud with rolled threads provides excellent conductivity. The removable stud option offers easy field replacement of the bushing stud with a standard 5/8" socket wrench in the event of damage or breakage in the field. A 7/64" hex has been provided in the portion of the stud which mates into the bushing insert. Should breakage occur, this feature allows for easy stud removal from the insert.
