● Mobile substation is composed of prefabricated cabin, secondary equipment cabinet （or rack）, High-voltage switchgear, cabin auxiliary facilities, etc. It is completed in the factory production, assembly, wiring, commissioning and other work, and as a whole transport to the project site, on the basis of installation.

● Prefabricated cabin and its internal equipment to achieve the integration of the whole set of equipment by the manufacturer, to achieve factory processing, reduce the secondary wiring site, reduce the design, construction, commissioning, workload, simplify maintenance work, shorten the construction cycle, effectively supporting the rapid construction of the power grid.

● It has the technical characteristics of standardization, modularization and prefabrication.
