What is the difference between pad mounted transformers and ordinary oil immersed transformers

Pad mounted transformer is a power transformer that combines plug-in fuses, backup fuses, tap changers, loop load switches (2/4 circuits), low-voltage distribution devices, and other corresponding auxiliary equipment on the basis of ordinary oil immersed transformers. Rated AC frequency 50Hz/60Hz, maximum working voltage up to 35KV, capacity 75KVA-3000KVA. Padded transformers provide many benefits to users, saving a lot of energy and bringing environmental benefits to owners. Higher efficiency not only extends the lifespan of pad mounted transformers, but also saves costs for owners in the form of lower energy bills and reduced ownership costs.
