768 DRIESCHER - Outdoor switches for railway lines Vacuum switching • The trend is to use a vacuum Basic research on switching in a vacuum began in Germany during the Seventies. At this time low-oil switches had become firmly established in medium voltage networks, based on their reliable operation over decades, and were accepted by users as reliable devices. In laboratory tests it proved that the vacuum switches were superior by far to the conventionally applied switching principles. All these requirements necessitate a switching unit with electrical properties that preferably do not...

768 DRIESCHER - Outdoor switches for railway lines Technical description General These Driescher outdoor switches are specially designed for railway applications. They meet the specifications according to the EN 50152-2. The 1-pole and 2-pole switches are designed for a rated voltage range from 15 kV to 29 kV and a rated current range of 630 A and 2000 A. The types of outdoor switch-disconnector and outdoor disconnecting switch mostly differ through the application of different cast-resin insulators (length and height of creepage path) as well as in the baseframes (U-profile and sheet-metal...

1-pole und 2-pole outdoor switch-disconnector FLaV 25- The 1-pole and 2-pole outdoor switch-disconnectors, types FLaV 25-2000-16-1B and -2B, are innovations developed specifically for the railway sector. Compared with the FLa 15/97-1B type, they offer increased short-circuit withstand capability. For this to be realised, it was necessary to provide the switching device with additional pre-arcing electrodes. Because of its modified functional characteristics, the switch-disconnector switch is capable of switching not only its rated making current of In 2000 A but also a short-circuit current...
