As we all know, dry-type power transformers mainly have two types: cast type (insulation grade is F) and open type (insulation grade is H grade). These two structures are mostly cast. I also know that the general dry-type transformers are used by users who require enclosures or cabinets, but some are only exposed indoors. With the widespread use of transformers, they are now popularized in more and more industries, such as subway traction, power distribution, living lighting, trolleybuses, power plants, etc. They can all be used. The capacity is generally not too large, even a few thousand kVA. It's big.
In addition, compared to oil-type transformers, dry-type power transformers have no oil, so there is no fire, explosion, pollution, etc., especially the new dry-type power voltage transformer series, the loss and noise are reduced to a new level, more transformers Placed in the same power distribution room as the low-voltage screen creates conditions.
