ZGS11-12 series American prefabricated box-type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a power transformation, metering, compensation control and protection device.
This product complies with the following standards:
《GB/T17467-1998 "High-voltage and low-voltage prefabricated substation》
《DL/T537-93 "Technical conditions for ordering 6-35KV box-type substation》
Altitude: ≤1000m;
Ambient temperature: -25°C~ +40°C;
Highest monthly average temperature:+30°C,
Highest annual average temperature:+20°C;
Relative humidity: daily average ≤95%, monthly average ≤90%;
Shockproof level: horizontal acceleration 0.4m/s, vertical acceleration 0.15m/s;
The installation location is free of severe impact, serious pollution, chemical corrosion, conductive dust and explosion hazard. When the normal usage conditions cannot be met, the user is asked to negotiate with our company to resolve the issue.
