The 200A Class Bushing Well meets the full requirements of IEEE standard.
It is designed for the termination of primary winding leads at the front plate of
fluid-filled apparatus rated at 8.3/14.4kV and 15.2/26.3kV. 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.
Continuous: 200 amps rms
Switching: 10 operations at 200 amp 10s rms at 14.4kA
Short Time : 10000 Arms symmetrical for 0.17s
3500 Arms symmetrical for 3.0s
