Product Profile of Dry Type Cast Resin Transformers [crgo Silicon Steel]

Vijai has been producing drytype cast resin transformers for more than 15 years. Vijai`s cast coils are well known for their extremely low levels of partial discharge.
Applications

• In service in diverse industries, electricity boards, nuclear / thermal / hydel power plants, railway traction and high-rise buildings, hospitals, subways, underground vaults, tunnels, schools, steel factories, chemical plants, etc. Where safety is of prime concern.

• Precise casting under vacuum ensures extremely low levels of partial discharge.

• Coils have smooth finish and are robust in construction.

• Vijai successfully conducted seismic qualification test on cast resin transformers supplied to nuclear power
