Indoor Voltage Transformers
Voltage transformers can be designed in single pole or double pole constructions as per client requirement. All indoor voltage transformers are manufactured using automatic pressure gelation casting process to ensure excellent insulation properties. Three phase voltage transformers are manufactured up to 11 kV range.
