Unitrans Power LLP offers a complete range of Dry Type Vacuum Pressure Impregnated (VPI) Transformers, designed for high reliability, durability, and low maintenance in demanding indoor and outdoor applications. Manufactured in compliance with IS, IEC, NEMA, ANSI, IEEE, and ISO standards, our VPI transformers are ideal for environments requiring high insulation performance, thermal stability, and mechanical strength – including data centers, industrial facilities, commercial complexes, and utility networks.The VPI process ensures primary and secondary windings are fully impregnated with epoxy varnish under vacuum and pressure, providing superior dielectric strength, enhanced insulation, and protection against moisture, dust, and environmental contamination. This results in long-lasting, reliable performance, even under harsh operating conditions. Technical Features Rating: Up to 5000 kVA Voltage: 480 V – 36 kV Frequency: 50 Hz or 60 Hz Cooling Class: ANAF or AN Temperature Rise: 60°C, 55/65°C Winding Material: Aluminium or Copper Standards: IS, IEC, NEMA, ANSI, IEEE, ISO Design Highlights VPI-impregnated windings for superior insulation and moisture resistance Excellent thermal performance and mechanical strength High dielectric strength with minimal partial discharge Optional IP55 enclosures (NEMA 3R/4X) for dust and rain protection F and H class insulation for high-temperature tolerance (155°C – 180°C) Quality Control Unitrans Power LLP follows ISO 9001:2015 quality standards, with stringent inspections and advanced testing at every production stage. Our quality management ensures maximum reliability, safety, and performance for every VPI transformer we deliver. Unitrans Power LLP delivers high-performance Dry Type VPI Transformers that combine safety, reliability, and efficiency, providing dependable power distribution for utilities, industries, and specialized applications worldwide.

Unitrans Power LLP is a leading manufacturer of Dry Type (Cast Resin) Transformers, Core Coil Assemblies, Transformer Tanks, CSS, and other transformer accessories, based in India. We specialize in producing dry-type transformers with ratings from 50 kVA to 5000 kVA and voltages from 440 V to 36 kV, continuously innovating through R&D for future-ready solutions. Our expertise ensures high-quality, reliable, and long-lasting performance for diverse power distribution needs. Unitrans Cast Resin Transformers (CRT) are particularly suitable for moisture-prone and harsh environments. The primary and secondary windings are fully encapsulated in epoxy resin, providing superior insulation and preventing moisture or dust from affecting performance. This non-hygroscopic design allows uninterrupted operation even in highly humid or contaminated areas. Optional metal enclosures up to IP55 (NEMA 3R/4X) further safeguard the transformer from dust, rain, and environmental stress.
