Silicone Oil Transformer

Silicone Oil Transformer

Midel esters can be shown to provide many advantages over silicone oil transformers, from enhanced performance to easier maintenance.

Our products have become the preferred transformer fluid for a wide range of applications, particularly in high risk areas such as underground and offshore.

Midel Improved Performance

MIDEL 7131’s superior moisture tolerance gives it the edge over silicone oil and other alternatives such as cast resin transformers.

Our dielectric ester-based fluids ensure greater stability over a sustained period, maintaining a high performance level throughout their lifespan.

Additionally, silicone oil has also been shown to have a negative effect on the environment. On the other hand, Midel has been thoroughly tested and shown to be non-toxic and non-hazardous to water, making it an environmentally friendly choice.

Midel Lower Maintenance

Silicone fluid has a tendency to seep through gaskets and seals, and can also form gels under partial discharge conditions.

In contrast, Midel has a proven track record as a low maintenance transformer oil, gaining a reputation as the ‘fill and forget’ fluid. This infrequent necessity for maintenance work significantly reduces transformer down time.
