YB6 Series Pre-Fabricated Substation(American Style Substation)
YB()series substation is suitable for 7.2kv and 12kv ring power supply and terminal power supply system as HV distribution calculation and protection equipment. In the substation except transformer there are 4 load switches, twq-position load switch,protection fuse and plug-in fuse in the HV side.We can install control electrical, distribution electrical, compensation electrical and meters.This substation can use indoor or outdoor .
The box stucture of this procuct is divided into two parts. In front is HV and LV operation room.
In the HV room including HV terminals, load switch,off-load switchgear, plug-in fuse, pressure relief valve, thermometer, oil level indicator and oil drain valve. In LV room including LV terminals.
In the back sector are oil tank and radiator, and transformer winding and iron, load switch and protection fuse are in the oil tank
