This current transformer has a hermetical structure, each sealing surface has been hermetically sealed by oil resistant rubbers. In order to ensure each of connection fastened well and not to make the gaskets compressed too much, all parts of the equipment are sealed up limitedly.

The current transformers which the insulation material is oil. It’s vertical structure, assembled by a metal expander, high voltage porcelain bushing, pressure relief valve, oil tank and oil-letting valve.

Oil Immersed Capacitor voltage transformer with carrier accessories, also known as coupling capacitor voltage transformer, is abbreviated to CVT.
