On June 1st, 2018, modular substationsolution provided by, CYG SUNRI assisted Yunnan Baoshan 110kV Jinchanghe Substation to be successfully put into operation, marking the successfuloperation of Yunnan's first fully containerized modular substation, anddistribution-mode complete-substationsolution has achieved further success.

110kV Jinchanghe Substation is divided into 6 modules including 110kV GIS prefabricated container combined equipment, outdoor main transformer, 10kV equipment prefabricated container combined equipment, secondary equipment prefabricated container combined equipment, 10kV reactive compensation prefabricated container combined equipment, and life assisted prefabricated container combined equipment. According to the overall planning of the plant area and access plan combined with the site topography. It achieved the goal of saving land, reducing costs, reducing on-site installation and commissioning and facilitating operation and maintenance. 110kV GIS prefabricated container combined equipment is located in the south side, double-layer three-dimensional combination container (10kV equipment prefabricated container + secondary equipment prefabricated container) is located on the north side, the outdoor transformer in the middle, the west side is equipped with 10kV reactive compensation prefabricated container and life assisted prefabricated container.

With the rapid development of power grids, the traditional substation construction mode is difficult tomeet the requirements of power grid construction,therefore the construction mod needs to be innovated. Theoverallsolution of CYG SUNRI modularsubstation is based on the concept of “standardized design, modularized assembly, industrialized prefabrication, and simplified construction”, with the goal of “less land-occupation, cost-saving, high reliability, and high construction efficiency. Itadopts the key technologiessuch asprefabricatedprimary/secondary combined equipment, optical/ electriccable plug and play, intelligent operation and maintenance, andadvanced application functions to reduce theland occupation, shorten the constructioncycle, improve the construction quality, reduce the construction cost, and obtain highly recognition fromthe users.
