Dry Type Transformer

This technology is also known as Corrugated Transformer . These Transformers are similar in function and operation like other conventional type Transformers but the construction of main tank is done with Corrugated Fins and MS Steels to provide the adequate cooling surface to avoid heating during operation. Corrugated Fins increase the surface area and take care of dissipation of heat, the Corrugated Fins once welded become integral part of Transformer’s Tank structure. The skills and workmanship of highly experienced and qualified welders ensures that the finished Tank is leakage free, the reliability of Tank’s design is proven by over pressure test.

Hermetically Shield Transformers have no Conservators and Silicagel Breather. The Dielectric Insulating Fluid / Oil is sealed completely in the Transformer Tank and thus not in contact with the atmosphere. The design prevents the entry of natural air into the Transformer Tank which avoids the sludging and oxidation of the Dielectric Fluid/Oil. Insulated Oil is not in contact with external air. Hence there is hardly any deterioration of Oil over a period of time. Such Transformers are virtually maintenance free.
