With a versatility in the spheres of an array of transformer types and brands, Urja has fulfilled numerous contracts successfully.We strive to encourage and sustain exceptional customer relationships through providing quality management services to our esteemed clients. Dry Vacuum Pressure Impregnated Transformers is one of our signature products which are fabricated using high quality materials.

Dry Vacuum Pressure Impregnated (VPI) transformers are a type of electrical transformers that are specifically designed to handle high voltages and deliver reliable power distribution. These transformers employ a unique manufacturing process called Dry VPI, which involves impregnating the windings with epoxy resin under vacuum and pressure conditions. This process ensures excellent insulation and protection against moisture, contaminants and thermal stress, resulting in a highly efficient and durable transformer.

The key material used in the construction of Dry VPI transformers is epoxy resin. This resin is chosen for its excellent insulating properties and its ability to withstand high temperatures. The windings of the transformer are made of high quality copper or aluminum conductors, which are carefully insulated with multiple layers of epoxy resin. The core of the transformer is typically constructed using high grade magnetic materials such as silicon steel laminations, which help to minimize energy losses and improve overall efficiency.


Dry Vacuum Pressure Impregnated transformers offer several notable features.

  • Their superior insulation properties ensure a high dielectric strength, preventing electrical breakdown and enhancing operational safety.
  • The VPI process eliminates air voids and ensures uniform insulation, reducing the risk of partial discharges.
  • These transformers have excellent resistance to moisture, chemicals and contaminants, making them suitable for harsh environments.
  • Additionally, the epoxy resin insulation provides excellent mechanical strength and thermal stability, allowing the transformers to operate reliably even in high temperature conditions.


Dry Vacuum Pressure Impregnated transformers offer several advantages over traditional transformers.

  • The VPI process results in improved solidity and longer life span by providing enhanced insulation and protecting the windings from moisture and contaminants.
  • The absence of air voids and the uniformity of insulation reduce the risk of partial discharges, minimizing the possibility of transformer failure. 3.These transformers also exhibit excellent thermal performance, dematerializing the heat efficiently and allowing for continuous operation at high loads.
  • Additionally, the epoxy resin insulation provides excellent protection against vibration and mechanical stress, making them suitable for various applications.
  • Furthermore, Dry VPI transformers are environmentally friendly as they do not contain oil, eliminating the risk of oil leaks or spills and reducing the need for maintenance and disposal procedures associated with oil filled transformers.
