The cabinet structure of ZGS series products is divided into front and rear parts. The front is the high and low voltage operating compartment; the high voltage compartment includes high voltage terminals, load switches, no-load voltage regulating tap switches, plug-in fuses, pressure release valves, oil temperature gauges, oil level gauges, and oil drain valves.
The low-voltage compartment includes low-voltage terminals and low-voltage power distribution devices. The rear part is the fuel tank body and the heat sink, the transformer winding and iron core, the high voltage load switch and the protective fuse are all in the fuel storage tank.
