Product introductionTechnical parameters
Dry-type transformer has the advantages of large short-circuit resistance, little maintenance work, high operation efficiency, small dimension and low noise, which is commonly used in places with high requirements of fireproof and explosion-proof. This type transformer is widely used in local lighting, high buildings, airports, docks, CNC machinery and others. Its cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). The transformer can operate continuously for a long time under rated capacity under natural air cooling. Output capacity of the transformer can increase by 50% under forced air cooling. It is suitable for intermittent overload operation or emergency overload operation. Due to the load loss and impedance voltage increase significantly when overload, it is not suitable for long time continuous overload operation.
1. The iron core is made of high-quality cold-rolled oriented silicon steel sheet, the surface is specially treated with protective resin, and full-inclined seam lamination structure is adopted.
2. The low-voltage coil is of foil winding structure made of high-quality steel foil. The high-voltage coil is of layer structure formed by vacuum epoxy casting technique. Transformers with this type of winding shows low partial discharge compared with similar product ;
3.This model features high mechanical strength, strong short-circuit resistance, good dust-proof and anti-fouling performance. Its service life is longer than another dry transformer.
4. The product's beautiful stainless-steel shell is durable and can provide better protection for the electrified parts of the transformer. It works well outdoors.
5. With excellent moisture-proof and corrosion-resistant performance, the product is safe, fire-proof and pollution-free. It's especially suitable for working in extremely harsh environmental conditions, and can restart without dry treatment after shutdown.
6. Good heat dissipation performance and strong overload capacity enables it operate with higher capacity when forced air cooling.
