Cast resin dry type transformer is a type of SC(B) dry transformer with epoxy resin, which is widely used in many fields. Its winding surface consists of high-quality protective material that forms the cover. Even in harsh environments such as dust and humidity, it will not affect the cast insulating dry-type transformer. The process characteristic of resin casting is that it must rely on molds and use special casting equipment to cast the coil in a vacuum state. The epoxy resin used is an insulating glue, so it is also called an epoxy cast resin dry type transformer.
