2. GB/T 11022 High voltage switchgear and controlgear standards

3. IEC 60298 AC metal-enclosed switchgear and controlgear for rated votlages above 1kV and up to and including 50kV

4. DL/T404 Indoor AC high voltage switchgear panel.

IV Ambient

· Environment temperature: -15°C to +40°C

· Relative humidity: daily average ≤95% monthly average≤90%

· Height above sea level: ≤1000m

· Earthquake magnitude ≤8

· No fire, explosion danger, serious pollution, or chemical erosion occasion.

V Main characteristics

· The structure of the cabinet is bolt by aluminum zinc alloy board after the process of CNC machine tool and multi bending technology;

· All the operation can be done after the cabinet door is closed;

· High protection degree, protect the intruder of sundries and pests;

· Simple and effective “five-prevention” lock function, protect error operation;

· Can adopt VS1 and CD4 vacuum circuit breaker;

· Easy replacement of the circuit breaker and free exchange of the drawers;

· The cabinet can be installed by the wall, maintenance in the front, which reduces the floor space;

· Large space of the cable room can connect many cables;

· The relay room and the cable room can respectively add a heater to avoid freezing or erosion.
