Dry Type Transformers
Kotsons Pvt Ltd manufacturers Dry Type Transformers. Kotsons Eco Friendly VP transformer coils are vacuum pressure impregnated in high temperature varnish. The process includes complete submersion in varnish under vacuum and pressure and regulated curing using PLC controlled equipment to ensure consistency. The finished coils are effectively protected against moisture, dirt, and most industrial contaminants. A 220°C Class NOMEX® Listed insulation system is used on KOTSONS OVDT VPI transformers regardless of specified temperature rating. This system accommodates a standard temperature rise of 155°C. Optional temperature rises of 90°C and 115°C and fan cooling allow for unsurpassed overload capacity.
