Siemens Energy has been designing and manufacturing medium- and high-voltage surge arresters for standard and special applications since 1925. We have produced surge arresters for railway systems for over 80 years. Continuous research and development, extensive know-how and global experience give Siemens Energy surge arresters a leading position in the overvoltage protection market. Their uncompromising quality ensures a long service life and reliability in every application.

Our portfolio consists of AC and DC surge arresters for a variety of different applications.

Our surge arresters for railway applications protect every part of a rail system, from traction substations, transmission lines, cables and catenary systems to rail vehicles for local, long distance and high-speed services up to 420 km/h. We offer several surge arresters for AC and DC railway applications up to 45 kV.
