The voltage transformer with isolating device is designed for maintenance and testing conveniently that there is no need to dismount VTs. The voltage transformer is provided with isolating device to open and close the connection between center conductor of barrier and active part. It is more cost saving for the design compared with disconnecting switch before voltage transformer on GIS.
Use imported materials and double-sealed for operating transmission rod to ensure hermetical seal completely and installation conveniently.
Mechanism operating for the isolating device, locking screw is fitted to fix hand wheel.
