200 A, 35 kV Class Tri-Clamp Bushing Well with Fixed or Removable Stud
The Cooper Power Systems 200 A, 35 kV class Tri-Clamp Bushing Well meets the full requirements of the latest revision of the IEEE Standard 386™ – 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, 16.2/28.0 kV (Canadian Applications) or 21.1/35 kV. The Tri-Clamp Bushing Well is externally clamped for sidewall mounting on single- or three-phase transformers filled with transformer oils or an approved equivalent bio-based fluid.
The Tri-Clamp Bushing Wells are molded with DuPont high performance plastics. These engineered plastics fulfill the required application needs for temperature stability, strength, toughness, low moisture absorption and retention of viable mechanical and electrical properties in humid high temperature environments. The gasket surfaces provide controlled compression and containment of the highly resilient Buna-N rubber gasket.
