Dry Type Transformers Manufacturers

Dry Type Transformers include solid insulation between winding turns, between each winding and another, and between conductors and ground dry transformers are usually air-cooled by self-ventilation or by forced air ventilation. Cast coil transformers are a variation of dry transformers and have an epoxy resin casting over each set of windings. With air cooling, the steel enclosure of dry transformers must include ventilation grilles. Most dry transformers are designed for indoor applications. Outdoor units are available but are very popular. Generally, dry transformers are cheaper to construct and provide shorter life expectancies.
