About Vpi Dry Type Transformers

Vpi Dry Type Transformers are offered by us that is a type of transformer which never uses any insulating liquid where its winding or core are immerged in liquid. Rather, the windings and core are kept within a sealed tank that is pressurized with air. The transformers, also known as cast resin transformers, are power transformers with windings encased in epoxy resin. The transformers are used in a wide variety of applications and can be installed indoors or outdoors. The offered Vpi Dry Type Transformers are used to increase or decrease voltages and currents in an electrical circuit.

Superior Safety and Durability

VPI Dry Type Transformers come equipped with self-extinguishing insulation and protection classes IP23/IP44, making them ideal for environments where fire safety and electrical integrity are paramount. Their rugged design resists humidity up to 95% RH and functions efficiently in ambient temperatures ranging from -25C to +50C.

Customizable Power Distribution

With capacities ranging from 100 kVA up to 2500 kVA and customizable output configurations, these transformers meet the diverse needs of industries, commercial buildings, hospitals, and data centers. The flexible mounting options and phase selections allow easy integration into new or existing power infrastructure.

Compliant and Efficient Performance

Manufactured according to IS 11171 and IEC 60076 standards, these dry type transformers undergo rigorous routine and type testing. Their low load loss and high efficiency (98-99%) ensure economical and reliable power distribution even in demanding operational scenarios.

FAQ's of Vpi Dry Type Transformers:

Q: How does the VPI process enhance transformer performance?

A: Vacuum Pressure Impregnation (VPI) improves the winding insulation by thoroughly embedding it with resin under vacuum, reducing the risk of moisture ingress and enhancing thermal performance, leading to longer service life and improved reliability.

Q: What environments are suitable for installing these dry type transformers?

A: These transformers are suited for industrial, commercial, hospital, data center, and renewable applications. Their IP23/IP44 protection, humidity resistance up to 95% RH, and robust temperature range ensure safe operation in both indoor and outdoor settings.

Q: When should a tap changer be opted for, and what types are available?

A: Tap changers are recommended when voltage adjustment is necessary for load variation. Both off-circuit and on-load tap changer options are available, allowing users to select based on operational needs and convenience.

Q: Where can the transformers be installed, and what mounting options are provided?

A: The VPI Dry Type Transformers are designed for floor-mounted installation, offering versatility for placement in substations, electrical rooms, or dedicated transformer bays in industrial and commercial settings.

Q: What is the typical process for routine and type testing of these transformers?

A: Routine and type testing are conducted as per IS 1180, IS 11171, and IEC 60076 standards. Tests include load loss measurements, short circuit impedance validation, insulation resistance checks, and verification of fire resistance and efficiency before shipment.

Q: How does using self-extinguishing insulation benefit users?

A: Self-extinguishing insulation significantly enhances fire safety by rapidly suppressing flames in case of electrical faults, minimizing damage and potential risks, making these transformers suitable for critical environments like hospitals and data centers.

Q: What is the expected operational life and maintenance requirement for these transformers?

A: Engineered for a service life exceeding 25 years, these transformers require minimal maintenance due to their robust design, high-quality materials, and durable insulation, ensuring long-term and reliable power distribution.
