Surge arresters for railway applications
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 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.
- 3EB4 - Silicone rubber surge arresters with composite hollow core design for use on traction vehicles and for fixed installation in AC and DC systems.
- 3EB5 – Silicone rubber surge arresters with Cage DesignTM for use on traction vehicles and for fixed installation in AC and DC systems.
- 3EB2 and 3EB3 – Surge arresters with silicone rubber housing for use on traction vehicles and for fixed installation in DC systems; A1 and A2 application. The 3EB2 is DC-B classified, the 3EB3 is DC-C classified.
