A leap forward in railway electrification

An overvoltage conductor saves a lot of money when it comes to electrifying aging railway lines.
Inventors of the Year 2019

Outstanding Invention

The transportation transition is already in full swing in the European rail network, and more and more lines are being electrified. Often, however, bridges are too low and tunnels too small for conventional contact lines. Axel Schmieder, Wolfgang Braun, and Martin Altmann of Siemens Mobility GmbH, along with Thomas Koch of Gas and Power, have invented a new arrester system solution that protects against lightning flashover despite the smaller clearances. The team was honored with the Inventor of the Year award in the “Outstanding Invention” category.
The financial expense is minimal when you consider that the savings are in the tens of millions.
Thomas Koch, Product Manager at Gas and Power
