Modern, fully electronic level crossing safety systems are equipped with efficient control technology. Unfortunately, disruptions of the systems due to lightning strikes are a regular occurrence. Special experiments for level crossing safety systems have been conducted in the DEHN test laboratory. These have proven that the arrester modules and protective circuit of the components in the safety system remain intact even in conjunction with lightning currents of 40kA.

Radio masts in GSM-R systems are usually situated in exposed locations because of the good transmission range provided there. The risk of a direct lightning strike is, therefore, particularly high. This calls for a professional concept to combat lightning and surges and thereby maximise system availability. Good to know: For many years now, renowned mobile radio companies have been putting their trust in DEHN’s know-how and technology.

Railway stations are the hub of mobility and often also shopping centres with a wide variety of shops and service providers. During thunderstorms, they also provide safe shelter for commuters and other travellers. Take advantage of the comprehensive DEHN product portfolio to establish lightning equipotential bonding and surge protection for all systems and building in compliance with the relevant standards.

Protect your employees. It is essential to avoid direct contact with overhead contact lines when working in the track area. DEHN insulating sticks, e.g., for cleaning the windscreens of power cars and locomotives, offer optimum protection here. Another problem is when the overhead contact line is in danger of touching the tracks. The DEHN portfolio includes the lightning-resistant SDS voltage limiting device which earths insulated tracks protecting systems and lives.

The use of electronic components in modern railway vehicles has become indispensable. Air-conditioning, electronic seat reservation, reading lights and passenger information and entertainment systems have all become a matter of course. These systems are particularly susceptible to transient overvoltage.
