ZGS11-12 combined transformer station (US transformer)
Product Details
Product overview
ZGS11 series combined transformer is a domestic and American box transformer launched by our company. Since the successful research and development, the company has been carefully built for many years. As an important power supply unit in urban and rural power distribution networks, this product is a power distribution product integrating high-voltage control substation and power distribution equipment, and is widely used in urban and rural power distribution networks.
The product will be high-voltage load switch, high-voltage fuse placed in the transformer oil, with the transformer body co-box or sub-box two structural forms. The oil tank adopts a fully sealed structure and is equipped with oil temperature gauge, oil level gauge, pressure gauge, pressure relief valve, oil drain valve and other components to monitor the operation status of the transformer. The product is divided into ring network type, terminal type and dual power supply mode.
