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 a three-phase common box type. It is used in 10kV rural and urban power systems, as the split and combined load current, overload current, short-circuit current and other similar places.


Executive standard

GB1984-2003 "High Voltage AC Circuit Breaker"

GB/T11022-1999 "Common technical requirements for high-voltage switchgear and control equipment standards"

IEC62271-10O "High Voltage AC Circuit Breaker"



Model Meaning



Normal Use Environment


1. Ambient temperature: -40°C~+40°C;

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 mist, and the pollution level is grade IV;

4. The wind speed does not exceed 34m/s (equivalent to 700Pa on the cylindrical surface);

5. Vibration or ground motion from outside the switchgear and control equipment is negligible;

6. Special Conditions of Use.

If you need to apply it under normal conditions of use different from the above, please negotiate with us.
