Lund becomes the fourth city in Sweden with a tramway

With good effect, Omexom finished the delivery of rectifier substations for the Lund tramway in Sweden. To meet the challenges in the project, for example busy roads, footpaths or cycle paths, and avoid disturbing Lund citizens, Omexom had to work on a new solution to carry out the project. Traditional construction would have involved extensive work with deliveries of building materials and electrical equipment that would have traveled through the streets. The delivered materials would have covered areas of the road where the substations would be located. This traffic would also have interfered with other simultaneous works.
