Siemens 3EB4 Silicone Surge Arrester in Composite Housing- Surge Arresters for Railway Applications

Siemens has been designing and manufacturing medium- and high-voltage surge arresters like 3EB4 Silicone Surge Arrester 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 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.
