ZGS11-Z transformer combination device is a novel outdoor complete set of power transformation and distribution device developed by our company by absorbing the advanced technology of "machine mounted transformer" widely used in the United States and introducing the invention patent and utility model patent technology of "three-phase non-interference distribution transformer switch combination device". After full analysis and research. It organically combines high-voltage power receiving equipment and distribution transformer and is prefabricated in the factory.

The high-voltage fuse and load switch equipped with the combined transformer (American box transformer) are concentrated in the transformer oil tank, with small volume, and can go deep into the load center, which can be used for both ring network power supply and terminal. It has been widely used in power grid transformation.
