The dry-type transformer cannot be installed in the open air, which is very dangerous. The dry-type transformer must be installed in a dry place during operation, so it cannot be installed in the open air.

Distribution box must be used for protection, with the protection grade of IP54 or above, and the transformer is not likely to be contaminated with water. In addition, the distribution box needs to consider heat dissipation, which can ensure that the temperature of the distribution box is lower than the operating environment of the transformer even when the outside air temperature is higher; Of course, other factors such as altitude should also be considered.

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharves, CNC machinery and other places. Simply speaking, dry-type transformers refer to transformers whose core and windings are not immersed in insulating oil. The cooling mode is divided into natural air cooling (AN) and forced air cooling (AF). During natural air cooling, the transformer can operate continuously for a long time under rated capacity. When forced air cooling is applied, the output capacity of transformer can be increased by 50%.
