Technical specifications
FZW33 12kV/24kV Outdoor AC vacuum type load disconnector is a new product adopts domestic existing mature load
breaker switch product ion experience and overseas advanced technology to design and manufacture. The load
breaker is composed of disconnect blade, vacuum interrupter and operation mechanism. vacuum extinguishing arc,
there are merits as strong extinguishing arc ability, reliable performance, long lifetime, small volume, no explosive danger
and no pollution to environment.
These disconnectors are suitable for powering networks of 12,24kV,to be used as a disconnecting devive of MV/LV
distribution transformers and to disconnect the MV outdoor tine.
It accords with the standards of IEC62271-102 & GB/T3804:3.6~40.5kV High voltage switches, IEC60694 &
GB/T11022: High voltage switch apparatus and control apparatus.
Vacuum Type Load Disconnector
Ambient condition
1. Altitude: 1000m;
2. Ambient temperature: -35 ~+50 C ;
3. Relative humidity: daily average 90%; monthly average 95%;
4. Earthquake intensity: 8 degree;
5. Applicable occasions should be free from inflammable, explosives and severe vibration.
