Outdoor High voltage isolation switch with fuse

Disconnector Switch

Outdoor High voltage isolation switch with fuse

    An electrical device for the reliable disconnection of certain sections of a high-voltage electrical network when there is no current in them. The use of isolating switches (either alone or in combination with high-speed short-circuiting devices) makes it possible to simplify the arrangement of switching points and transformer substations and to eliminate expensive high-voltage circuit breakers.

    Standard

     IEC/IEEE and DVE-recommendation standards especially comply with DIN VDE 0670 part 

     IEC-60265, IEC-129

     Features

     All steels are made of either in stainless steel or hot-dip galvanized steel.

     1. Solid and stable base frame.
     2. main contact with ice protection.
     3. Polymer insulators or alternatively in porcelain.
     4. Minimal sag for the line-connection between two fixed terminals.
     5. Completely maintence antirust Aluminium alloy Arc chamber.
     6. Switching-off procedure without external arc.
     7. Short circuit making capacity under specific conditions possible
     8. Fixing on the supporting structure either by clamping(free setting) or screwing (holes in the   base frame)
     9. Easy on-site installation and setting.
