Standard Features
1)The transformer part and the control cabinet part of the United States variation, of which the transformer part is a fully sealed structure, and the insulating oil can be two types of high ignition point oil or ordinary oil.
2)The control cabinet is divided into a high-voltage room and a low-voltage room.
3)The high-voltage room is equipped with: high-voltage cable plug, lightning arrester, load switch operating handle, non-excitation tap switch handle, plug-in fuse, pressure release valve, thermometer, pressure gauge, oil Position gauges, oil filling plugs, oil drain valves, etc., load switches, off-excitation tap changers, plug-in fuses, etc. are all immersed in transformer oil together with the transformer core. The high-voltage cable and the transformer are connected by elbow cable connectors.
4)The low-voltage side can be installed with air circuit breakers, current transformers, as well as electric energy meters, ammeters and voltmeters, and output circuits and capacitance compensation devices can be configured according to user needs.
