    As a package unit for power transformation, power distribution, metering, compensation, control and protection, ZGS Combined-type Transformer (American type) is used in 12KV loop net power supply, dual power supply and terminal power supply systems. Except for transformers installed in the substation, four-station or two-station load switch, standby protection fuse protector and pull-out fuse are equipped in the high voltage module. Control apparatus, distribution apparatus, compensation unit and metering unit can be installed in the low voltage units upon customers' request.

    The models of the transformers in the product are S11-M and S13-M, and the product is developed based on domestic actual situation with a state-of-the-art technology brought in from abroad. Featuring a small volume, low noise and low loss with full protection, easy installation and maintenance, the whole set can be used in newly constructed communities, green belts, parks, traffic stations, wharfs, hotels, construction site and airports, etc.
