FZW32-12/24/40.5 Outdoor HV Vacuum Disconnect Load Break Switch
 
FZW32-12/24/40.5 Outdoor HV Vacuum Disconnect Load Break Switch

Summary
FZW32-12/24/40.5 Outdoor AC high voltage disconnect vacuum load break switch is a new product adopts domestic existing mature load break switch production expe rience and overseas advanced technology to design and manufacture. the load break switch is composed of disconnect blade, vacuum interrupter and ope~tion 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. It accords with standards of IEC62271-103 High voltage switches.
