Structural Features
The overall structure of the substation consists of two high-voltage switch rooms on the 40.5kV side and the 12kV side, a relay protection room, and a transformer. The outer shell of the high-voltage switch room and relay protection room can be made of stainless steel plates, steel plates, or composite boards. Stainless steel structures possess exceptional corrosion resistance and good mechanical strength. Each component of the steel plate structure undergoes special anti-corrosion treatment. Meanwhile, composite boards feature bright colors, aesthetic appeal, and thermal insulation properties. The transformer is located between the high-voltage switch rooms on the 40kV side and the 12kV side, directly installed on the foundation, making it convenient for both users and manufacturers to install.
