Optimal solutions for rail systems

In railway systems Siemens surge arresters help make sure that lightning overvoltages do not result in damage to the insulation in system components and the traction vehicles themselves. They protect traction substations, transmission lines, cables, and catenary systems as well as rail vehicles for local, long distance, and high speed services.

Siemens surge arresters meet all worldwide requirements for the overvoltage protection of rail vehicles and rail electrification. The comprehensive portfolio makes it possible to find the ideal surge arrester for any conceivable application and meet even specific demands, such as:

• High mechanical stability to withstand vibrations and high wind speeds
• Extremely reliable pressure relief behavior when special protection is required
• Excellent pollution layer characteristics for coastal and desert regions and areas with extreme air pollution
