Cast Resin Dry Type Transformer

Cast Resin Dry Type Transformer
IEC/ANSI Cast Resin Transformers from TAILI Electric, is difference from oil
type transformer is that it must be installed inside with the core and winding
are not impregnated in insulating oil, are widely used in local lighting, high-
rise buildings, airports, docks, CNC machinery and equipment, etc. Its cooling
method can be divided into natural air cooling (AN) and forced air cooling
(AF). With natural air cooling, the cast resin transformer can operate
continuously at rated capacity for a long period of time. With forced air
cooling, the fire resistant transformer output capacity can be increased by up
to 50%. It is suitable for intermittent overload operation, or emergency
accident overload operation; because of the load loss and impedance voltage
increase during overload, it is in non-economic operation, so it should not be
in long time continuous overload operation
