Product Name: Outdoor Bar Type TAT Current Transformer

1  Product instructions
The current transformers are outdoor products of a busbar going thru type, with a metal protective case
(stainless steel or aluminium). Between the case and the case cover, a silicon rubber bar is used for seal and isolation. At the ring direction of case and cover, there is a gap for magnetic isolation, and there is a earthing
bolt on the case and cover correspondingly. It is much suit for going in and out bushing type current
transformer of 66~220kV PASS switchgear.
