The electric substation construction is a complex program. Here is some advice from SPL, a splendid substation manufacturer in China.

The 35kV high-voltage power distribution room, secondary equipment room, centralized control room and GIS of the precast cabin substation are prefabricated, and the container scheme is adopted for SVG control. Due to the space limitation of the site, GIS is not above the high-voltage distribution prefabricated cabin, which is set in the north of the low-voltage side of the main transformer and connected by common box sealing bus. Its advantages are factory assembly, site assembly, lighting, HVAC, fire, monitoring pre-installation, site construction workload is small, civil construction workload is small, the construction cycle is short; The disadvantage is that GIS is arranged on the second floor, the crane equipment cannot be installed in the cabin, and maintenance is difficult.
