Safety through rapid, safe, and reliable earthing in the event of an accident, evacuation, and maintenance

Our automatic earthing device (AED) is a safety system that automatically and reliably earths electrical overhead contact line systems and provides reliable indication of effective earthing.

AEDs are used wherever the areas to be secured are large and complex, in order to ensure rapid, safe, and complete earthing after disconnection – for example in difficult terrain, in cities with high traffic volumes, with large distances between tunnel portals – or if the fire service is too far away from the location or the local fire service has no experience with earthing overhead contact lines.
