A dry-type transformer is a stationary, solid-state device designed for
safe and reliable power distribution in industrial, utility, and commercial applications. Unlike
oil-filled transformers, dry-type transformers use high-temperature insulation systems,
eliminating the risk of leaks and environmental hazards. These transformers are
maintenance-free, highly durable, and designed for medium-voltage applications, making them
ideal for power distribution in critical facilities such as chemical plants, underground
substations, and remote power stations.
Engineered to IEC 60076 and IS 11171 standards, dry-type transformers feature copper or aluminum
windings insulated with varnish or cast resin, ensuring high efficiency and thermal resistance.
With advanced air-cooled (AN) technology, they operate efficiently in high-temperature
conditions while maintaining low noise levels and minimal energy losses. Their compact design
and fire-resistant materials make them perfect for urban power grids, oil & gas industries, and
underground substations, ensuring long-term performance with enhanced safety.
