Dry type Transformer
Three-phase Epoxy-resin Dry-type Transformers are in conformity with standard of IEC726, GB6450, GB/T10228-1997, with features of low loss, compact and light weight, low noise level, damp-proof, high mechanical strength, flame resisting, strong overload ability and low partial discharge quality. They are applicable to power transmission and distribution system, especially to heavy load centers and places with special fire protection requirements.
