Electrical &amp; Power Generation

Hermetically sealed oil-filled distribution transformers are built in a fully closed tank, typically with a gas cushion instead of an open conservator. They tolerate outdoor moisture and contamination better. Common on distribution feeders and industrial supply points. Rating and voltage class follow the project brief.
