Dry transformers structural features
1)Box coil: The low -voltage winding uses the entire copper foil, along with the F -class turning insulation on the dedicated low -pressure foil winding machine.
2)Foil coils are well solved with low pressure, large -current coils around the product, large stress, unbalanced amnf -balancing, poor heat dissipation effects, and outstanding problems such as winding spiral angles, and unstable artificial welding quality.
3)At the same time, the transformer winding is seized with resin, solidified and shaped, and moisture -proof and pollution -proof.
