ZBW-40.5 Combined Substation: Reliable 40.5kV & 12kV Switchgear from Leading China Suppliers and Factory
Model and Definitions
Application Conditions
Altitude: ≤1000m; Ambient temperature: -15℃ to +40℃;
Temperature: Maximum monthly average temperature +30℃, maximum annual average temperature +20℃;
Relative Humidity: Daily average not exceeding 95%, monthly average not exceeding 95%;
Wind speed: Wind speed not exceeding 34m/s;
The installation site should be free from severe shocks, serious pollution, and chemical corrosion, as well as conductive dust and explosion hazards. If normal application conditions cannot be met, please consult with our company for solutions.
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.
Frequently Asked Questions (FAQ)
What are the ambient temperature limits for this substation?
The substation is designed to operate in ambient temperatures ranging from -15℃ to +40℃. The maximum monthly average temperature should not exceed +30℃, and the maximum annual average temperature should not exceed +20℃.
What is the maximum installation altitude allowed?
The standard installation altitude for this equipment is less than or equal to 1000 meters (≤1000m). For higher altitudes, please consult the company directly for customized solutions.
What materials are available for the outer shell of the switch rooms?
The outer shell of the high-voltage switch rooms and the relay protection room can be constructed from stainless steel plates, steel plates, or composite boards, depending on your aesthetic and environmental protection needs.
How does the substation resist corrosion and environmental damage?
Stainless steel options provide superior corrosion resistance and mechanical strength. Steel plate structures undergo special anti-corrosion treatments, while composite boards offer thermal insulation and a bright, aesthetic appeal.
Where is the transformer installed within the substation layout?
The transformer is located directly between the high-voltage switch rooms of the 40.5kV (or 40kV) side and the 12kV side. It is designed to be installed directly on the foundation, facilitating easy installation for both manufacturers and users.
