Model meaning
ZW8-12(G) outdoor high-voltage vacuum circuit breaker, three-phase AC 50Hz outdoor high-voltage switchgear. It is composed of operation, conductive circuit, insulation system, seal and shell, and the overall structure is three-phase common box type. It is used for 10k√ rural power grid and urban power grid power system, used for dividing and combining load current, overload current, short-circuit current and other similar places.
Executive standards: GB1984-2003 "High Voltage AC Circuit Breakers"; GB/T11022-1999 "Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards"; IEC62271-100 "High Voltage AC Circuit Breakers"
Model meaning
Normal use environment
1. Ambient temperature: -40℃~+40℃;
2. Altitude: ≤3000m (if the altitude increases, the rated insulation level will increase accordingly);
3. The surrounding air can be polluted by dust, smoke, corrosive gas, steam or salt spray, and the pollution level is IV;
4. The wind speed does not exceed 34m/s (equivalent to 700Pa on the cylindrical surface);
5. Vibration or ground motion from outside of switchgear and control equipment is negligible; 6. Conditions of use.
If you need to apply it under normal use conditions different from the above, please negotiate with us.
