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.
Product introduction
American box-type substation enclosure series, including YB37P, YB37J(30-1000KVA), YB37Z(30-1600KVA) is used in 10kv loop net power supply, double- power supply or terminal power supply systems as HV power distribution measuring, compensation control and protection equipments.
This series is completely sealed and insulated. The HV load switch, HV fuse can be placed in transformer oil. These elements can be seperated from transformer body or enclosed within one compartment with transformer body.
The material of this is qualified cold-rolled steel plates that have high bending, compact resistance and ensile strength.
The surface has high anti-corrosion property with static powder coating processing. The structure is compact with an area of 1/3 of equal volume.
It features of easy installation, maintenance, high compactness, high sunshine and radiation resistance, high security and good protection.
Note: The color and external can be adjusted as per client requirments.
