Single-pole disconnect switch FLa 15/97-1B series

for railway applicationsoutdoor

General information Our good and successful cooperation with Deutsche Bahn AG already began in the fifties. Over the course of time more and more importance was attached to the reliability of traction power supply which made it necessary to design switching devices with new technologies. Initial efforts already commenced in the Sixties in the field of vacuum technology and this led to the first outdoor line sectionalizers* with vacuum interrupter. Based on a very intensive cooperation with DB (German Rail) we were able to install an outdoor switch disconnector FLa in the railway network for trial operation. Today our product program for railway operations covers a comprehensive range of products for 1 and 2-pole switches including accessories, enabling us to meet rail technology requirements worldwide. A list of references relating to various railway projects includes the fooloweing: 25 kV Madrid-Barcelona; 25 kV Tunnelstrecke Taipei; 27.5 kV Harbin-Dalian, China; 25 kV Havenspoorlijn, Netherlands; 25 kV Gerdermobanen, Norwegen; 25 kV Spoornet, South-Africa; 25 kV HZ-Hvratske, Kroatien .......
