SC(B)10/11/13 3 Phase Dry Type Casting Transformer

The coil of SCB11 Cast Resin Dry Type Transformer is encapsulated with epoxy resin, which is not easy to burn, fireproof, explosion-proof, maintenance-free, pollution-free, small in size, etc., and can be directly installed in the load center.

Its scientific and reasonable design and casting process, make the product partial discharge is small, low noise, heat dissipation ability is strong, can be in the forced air-cooled conditions, in 140% rated load long-term operation, and equipped with intelligent temperature controller, with fault alarm, over-temperature alarm, over-temperature tripping and black gate function, and through the RS485 serial interface connected to the computer, can be realized in a centralized monitoring.
