Power distribution grids are becoming more and more complex. This is why Siemens focuses on helping customers improve the reliability and efficiency of their distribution grids. This keeps them a step ahead of their challenges, from the control center via the grid to the consumer. Outdoor switching devices are essential components of medium-voltage distribution grids with overhead distribution lines. Siemens’ comprehensive portfolio of outdoor vacuum switching devices has been especially designed for a wide variety of climatic conditions. Thus, type-tested reliability as well as long...

Benefits and features • Maintenance-free switch unit • High breaking capacity • Low contact resistance • Interrupter optimally adapted to your application Vacuum interrupters from Siemens work in a particularly reliable and safe manner. The arc, which results when the switching contacts are opened, can be physically well controlled in the vacuum. As the contact gap is de-energized during the current zero crossing, a self-extinguishing switching principle is created, which minimizes wear on the contacts. This results in a substantially higher electrical switching performance and a...

While traditional in-line tension disconnects offer line crews a temporary isolation of a line at non-designated switching locations, the lack of a ganged switching capability creates operational inefficiencies. These are due to: • Restrictions in load breaking capability • Restrictions in load pickup • The risk of ferro-resonance as an effect of single-phase switching operations • The additional time to isolate upstream devices prior to operating the in-line disconnect. Siemens has addressed all of these problems by adapting the switching unit of the proven Fusesaver circuit-breaker into a...

Especially designed for outdoor installations, switches are ruggedly built, reliable devices that splice right onto the line. As switch-disconnectors they serve to safely support the conductor while providing the required isolating distance for quick and safe line maintenance. By the nature of its application, a line tension switch must mechanically support the line and provide high-voltage electrical isolation when the switch is in open position. To achieve this, the latest porcelain and polymer insulators may be chosen. The switches can be used in medium-voltage substations, in the line...
