Switchgear chosen for Stockholm rail tunnel

Electrical Review Logo

Eaton has been chosen by Goodtech Projects & Services AB for its SVS/08 modular Medium Voltage (MV) switchgear for use in the Trafikverket’s City Line project based in Stockholm, which also includes the delivery of substations.

Trafikverket is the state-run Swedish Transport Administration, which has started a huge effort that will see commuter trains running through a new six kilometre tunnel, greatly increasing the capacity of the rail network in Stockholm and the surrounding area.


The initiative involves the construction of two tunnels – a running tunnel for the trains and a service tunnel to act as an emergency escape route and to house ancillary equipment. Within the service tunnel, 11 substations operating at 22 kV will be provided. Goodtech Projects & Services has contracted Holtab AB, one of Scandinavia’s leading substation manufacturers, to build the substations. All these substations will be equipped with Eaton’s SVS/08 MV switchgear.
