Take Epoxy Resin Cast Dry-Type Transformer Power Supply Distribution Transformer 10kv 35kv for example, Epoxy Resin Cast Dry-Type Transformer Power Supply Distribution Transformer 10kv 35kv is a power transformer, and the type is a dry-type transformer. Dry-type transformers rely on air convection for cooling and are generally used for local lighting and electronic circuits. Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery, equipment, etc. Simply speaking, dry-type transformers refer to transformers whose iron cores and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). Under natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be in continuous overload operation for a long time. The winding method is the high-voltage coil, low-voltage coil, frequency: 50Hz/60Hz, and the insulation level is FH.
Features and advantages include good overall rigidity, high mechanical strength, strong resistance to sudden short circuits, shock absorption and high impact performance.
