Liquid filled Distribution Transformers

Our liquid cooled power and distribution transformers are available both newly manufactured or re-engineered.

Oil immersed power transformers can operate with higher power ratings and higher voltage applications than their cast resin counter parts. Oil cooled transformers are widely used in applications of more than 20000kVA.

Where fire safety is an issue or an environmentally friendly solution is preferred we can supply midel filled transformers as an alternative.
