The university campus is rather complicated, and at least three distribution rooms or box-type transformers should be built, with the grade of 10kv, so a university has three box-type transformers.

Box-type transformer (usually referred to as box-type transformer) concentrates the traditional transformer in the box shell, which has the advantages of small volume, light weight, low noise, low loss and high reliability, and is widely used in residential quarters, commercial centers, optical stations, airports, factories, mines, enterprises, hospitals, schools and other places.
