Engineered for superior safety, energy efficiency, and dependable performance in commercial, industrial, and critical power applications.
Safe & Efficient Power Distribution Solutions
Voltek Dry Type Transformers are designed to deliver reliable, maintenance-friendly, and environmentally safe power distribution. Built with premium insulation systems and precision-engineered windings, they offer exceptional thermal performance, low energy losses, and enhanced fire safety, making them ideal for indoor installations and demanding industrial environments.
Our Dry Type Transformer Types
Cast Resin Dry Type Transformers
Cast Resin Dry Type Transformers are manufactured using vacuum epoxy resin casting technology where the high-voltage windings are completely encapsulated in epoxy resin. This construction provides exceptional protection against moisture, dust, chemicals, humidity, and harsh environmental conditions while offering superior mechanical strength and fire safety.
These transformers are ideal for critical installations where maximum operational safety and long-term reliability are required.
VPI Dry Type Transformers
Vacuum Pressure Impregnated (VPI) Dry Type Transformers are manufactured by impregnating the windings with high-quality insulating varnish under vacuum pressure. This process enhances dielectric strength, improves thermal performance, and provides dependable protection against dust and humidity while maintaining excellent cooling characteristics.
VPI transformers offer an economical, reliable, and energy-efficient solution for industrial and commercial power distribution systems.
Built for Performance. Designed for Safety.
