The 12～40.5kV prefabricated cabin-type substation is based on the core concept of “standardized design, modular combination, factory prefabrication, and simplified construction” by Tianan Electric based on the State Grid. It is based on “small area, low cost, high reliability, and high construction efficiency”. "A new product developed for the purpose. Use prefabricated cabin-type primary/secondary combination equipment, optical/cable plug-and-play, intelligent operation and maintenance, advanced application functions and other key technologies to reduce the area of the substation, shorten the construction period, improve the construction quality, and reduce the construction cost The goal.
