ZBW(YB)17-10 Series HV/LV Prefabricated (American type)Substation
Applications
The combined American box change is a transformer body, high voltage load switch, fuse and other components.
It is placed in the transformer oil tank. Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance free. Widely used in residential quarters, high-tech centers, factories and mines, airports, stations, schools.
The combined transformer is a new type of power distribution equipment (also known as the American box change).
It is a new type of product specially designed for the distribution network by introducing the most advanced technology and design concept from abroad, combined with domestic conditions.
The combined American box type substation put the transformer body, high-voltage load switch, fuse, and other components together in the transformer oil tank. Because it is immersed in oil, the component volume is greatly reduced, the structure is more compact, and the installation is convenient and flexible.
Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance-free. Combined transformers are especially suitable for load centers, residential centers, hospitals, schools, airports, stations, etc. of urban power grids to reduce losses and improve power quality.
