Fast, safe, cost-efficient
Portable soft ganged switch for distribution networks
Connect and disconnect the feed to power lines at the push of a button – quickly, safely and without complications. We offer an easy way to perform maintenance on your distribution networks: with portable soft ganged switches for temporary isolation applications. The portable switch provides a fast, safe and cost effective way to create points of temporary isolation on the distribution network. This helps to ensure that outage times and the number of affected customers are kept to a minimum when maintenance work is carried out.
Whilst traditional in-line tension disconnects provide line crews with a way to temporarily isolate a line at nondesignated switching locations, the lack of a ganged switching capability creates operational inefficiencies due to:
- Restrictions in load breaking capability
- Restrictions in load pickup
- The risk of ferro-resonance due to single phase switching operations
- The additional time to isolate upstream devices prior to operating the in-line disconnect.
Siemens has addressed all these problems by adapting the switching unit of the proven fusesaver outdoor vacuum circuit-breaker into a pre-configured 3-phase synchronous portable switch kit. The phase-to-phase communication is achieved via the built-in radio system in the communications module. The switch units are suitable for in-line tension, line hung of cross-arm mounting on already exiting connection points for simple installation and visible isolation. The devices are electrically floating and require no earthing.
