Middle Voltage Switchgear

This middle voltage switchgear can meet the requirements of GB3906, IEC298 and so on, which has the "five-prevention" functions of preventing the error operation of the circuit breaker, preventing the push-and -pull of the hand drawer on-load, preventing from switching the grounding switch with power on, preventing the power transmission of the grounding switch in grounding position and the power spacer to prevent error entry. This switchgear is truly a power distribution device with super performance, which can adopt VD4 vacuum circuit breaker from ABB Company or VS1 vacuum circuit breaker at home.

Environment temperature: -15℃ to +40℃

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.

The structure of the middle voltage switchgear 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.
