China OEM 20kv Transformer Factories – 11kv class dry type transformer – JSM TRANSFORMER Detail:

SCB10 SERIES 11kV CLASS DRY TYPE TRANSFORMER

Features of Products

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and other places.
Simply speaking, dry-type transformers refer to transformers in which iron cores and windings are not immersed in insulating oil.
Cooling methods are divided into natural air cooling(AN) and forced air cooling (AF). During natural air cooling,
the transformer can operate continuously for a long time at rated capacity. When forced air cooling occurs, the output capacity of the transformer can be increased by 50%.
Suitable for intermittent overload operation or emergency overload operation; Since the load loss and impedance voltage increase greatly during overload and are in non-economic operation,
it should not be kept in continuous overload operation for a long time.
