Dry Type Transformer

SC(B)11 10kv Epoxy resin low voltage dry type power transformer transformer

SC(B)13 10kv Three Phase Epoxy Resin Cast Dry Type Power Transformer

A dry type transformer is a motionless piece of equipment that uses environmentally acceptable temperature insulation systems. They are also known as “cast resin type transformers.” The transformer is housed in a case with adequate ventilation, Because of the cooling constraints, dry type transformers’ maximum voltage is restricted to 35kV.
The scientific and reasonable design and casting process make the product have less partial discharge, lower noise and stronger heat dissipation capacity. Under the condition of forced air cooling, it can operate for a long time under 125% rated load. Dry type transformers have a wide range of commercial, industrial, and utility applications. They are commonly utilized in small and medium-voltage applications in electric equipment.
