YB series substation are suitable for 7.2kV and 12kV ring network power supply.For the double-power supply or terminal-power supply, they are working as the HV distribution calculation,compensation control;and protection device.Inside the substation, except for the transformer, for HV side there are four-polar load switch, two-polar load switch, back­ up protective fuse and plug-in fuse. For LV side there are control devices, distribution devices, compensation device and electric energy meter required by customers.YB series substation; can be used for indoor or outdoor places, which are widely used in the industrial park, residential area, commercial center and tall buildings.
