Box-type Substation ( U.S. Substations )

Short Description:

ZGS口-12/0.4 series Box-type Substation ( U.S. Substations) is mainly used in the ring main system with voltage of 12KV and urban power grid transformation, indoor and outdoor universal, applicable to various public places and industrial and mining enterprises, airports, subways, ports, stations, highways and other transportation places.
The equipment overall structure is compact, is an ideal complete set of power distribution equipment for 12KV power conversion and distribution of power grid control and electricity consumption terminals, Products meet the requirements of IEC, GB/T11022, JB10217 and other standards.
Combined American box-type transformer is a transformer body, load switch, fuse and other components together in transformer oil tank, component volume is greatly reduced, compared with conventional civil substations, box-type substations with the same capacity usually occupy only 1/10~1/5 of conventional substations, which greatly reduces design workload, construction workload and construction costs.
