Dry Type Transformer

Dry-type transformer is a kind of power transformer that does not use insulating oil and relies on air or resin insulation for cooling. It is fireproof, environmentally friendly, and maintenance-free, and is suitable for indoor, subway, data center and other places with high safety requirements. The core advantages are no risk of oil leakage, low noise, and flexible installation, but the capacity is usually smaller than oil-immersed and the cost is higher.

Grounding transformers are often used to provide an artificial loadable neutral point for system grounding at ungrounded points in the system. The neutral point of this product is connected to an arc suppression coil or resistor, and then grounded. It can be equipped with a secondary winding of continuous rated capacity as the power supply for the station (station).
