The transformer uses a grain-oriented electrical steel core and a hermetically sealed corrugated tank. The corrugated tank accommodates changes in oil volume during operation while limiting contact between the insulating oil and the surrounding air.
A three-phase oil-immersed transformer for utility networks, industrial facilities and outdoor power distribution.
