The Gotthard Base Tunnel is roughly 57 kilometers in length, making it the longest railway tunnel in the world. It was built by AlpTransit Gotthard AG, who commissioned Transtec Gotthard as the general contractor for the railway applications. ABB was hired as a sub-contractor to provide medium voltage supply for the tunnel’s infrastructure in addition to delivering transformers that provide the power required to maintain the 50 Hz grid.
In the recently published issue of our Power magazine a detailed article describes how ABB provided essential electrical components for the 50 Hz power supply of the Gotthard Base Tunnel infrastructure and its energy efficient ventilation system, including a Conceptpower DPA UPS.
