Vacuum Pressure Impregnation (VPI) dry type transformers stand out as a reliable, efficient, and environmentally friendly option. Designed to operate without oil and with exceptional durability, these transformers are used in a wide range of industrial applications. At Varelen Transformers, we pride ourselves on producing cutting-edge VPI transformers tailored to meet the diverse needs of industries like data centers, building, oil and gas, renewable energy,
Vacuum Pressure Impregnated (VPI) transformers are vacuum pressure impregnated with a high temperature polyester varnish. VPI ventilated dry-type transformers are designed to meet most commercial and industrial applications. VPI transformers provide excellent mechanical and short circuit strength, no danger of fire or explosion, and no liquids to leak.
VPI transformers are typically air or water-cooled, eliminating the need for oil-based cooling systems. This makes them safer, cleaner, and better suited for environmentally sensitive or indoor applications. They are available in various configurations to handle different voltage levels and power capacities, making them a versatile choice for a broad range of industries.
VPI dry type transformers advantages, including:
Environmentally Friendly: VPI transformer are no oil, reducing the risk of leaks and environmental contamination.
Enhanced Safety: The non-flammable 220°C insulation system significantly lowers the risk of fire.
Cost-Effective Installation: No need for oil containment systems reduces initial setup costs.
Durability: The vacuum pressure impregnation process provides robust insulation and resistance to environmental factors.
Compliance: international standards like IEC, IEEE, and UL ensures quality and reliability.
VPI dry type transformers are ideal for applications requiring robust performance, environmental safety, and minimal maintenance. Here are some common scenarios where they excel:
Indoor Installations: Perfect for data centers, commercial buildings, and hospitals where fire safety is a priority.
Harsh Environments: Their durable enclosures protect against dust, moisture, and pollution, making them suitable for mining and heavy industry.
High Power Applications: Direct water cooling options allow them to handle currents exceeding 20kA.
Renewable Energy Projects: They’re commonly used in wind and solar power systems due to their environmental compatibility.
Oil and Gas: Reliable performance in challenging conditions ensures uninterrupted operations.
At Varelen Transformers, we understand that no two projects are the same. That’s why we offer customization options to ensure our VPI transformers meet your exact requirements. Our engineering team works closely with clients to tailor:
Cooling Systems: Choose between air or water cooling to suit your operational needs.
Enclosure Types: From IP21 to IP65, we provide enclosures that protect against rain, dust, and aggressive environments.
Material Options: Select from different grades of steel and conductor materials to optimize performance.
Voltage and Capacity: We manufacture units up to 10MVA with insulation classes up to 1.2kV.
VPI dry type power transformers represent the perfect blend of safety, efficiency, and adaptability. At Varelen Transformers, we’re proud to deliver solutions that not only meet but exceed industry expectations. Whether you need a standard transformer or a highly customized unit, our team is dedicated to providing the best in quality and performance.
