Types of Dry Transformers

There are different types of dry type transformers. In different situations and applications, dry type transformers are used. For those searching for radiance protection and advanced mechanical power, a cast oil transformer is recommended for harsher environments.

• Open Wound Transformer

Considered as a top power transformer distributor in Hyderabad, we manufacture different types of transformers. Open wound transformer gets its name through its manufacturing process. In its manufacturing process, "dip-and-bake" method is utilized. The coils used in these types of transformers are heated, dipped in high-temp varnish and then baked known as the open wound method.

• Vacuum Pressure Impregnated (VPI)

Normally, VPI transformers are used for commercial as well as industrial purposes. Vajra Transpower is one of the best power transformer manufacturers in Hyderabad. These types of Vacuum pressure impregnated have a high-temperature insulation which ranks over ‘O’ as well as ‘K’ fluid classifications. VPI transformers are made up of materials which can withstand at very high temperatures. These types of transformers are also moisture-resistant polyester sealant, which is typically applied with a vacuum pressure impregnation strategy.

• Vacuum Pressure Encapsulated (VPE)

We can compare VPE transformers with VPI type of transformers. But, instead of polyester, they are made up of silicon-based resin, this generates a thicker coating which is highly resistant to moisture, salt as well as high humidity, making it an extraordinary choice for harsher environments. These types of dry type transformers are used in environments that are susceptible to acids, chlorides and also alkalis.
