Renewal of Electrical System Alleeweg

As part of the rehabilitation of the electri-cal system in Murifeld district in southeast Bern, the entire MV and LV network was redesigned. This included design of the construction works as well as the prepara-tion of the cable diagrams. The project consisted of the replacement/construction of 8 distribution boxes as well as the replacement of the cable conduits over a length of 1,000m. To optimise the route, the entries of two transformer stations were set deeper. In total 82 electricity house connections were renewed, partly with blow propulsion and partly as cut and cover. The new house connection boxes and the location of the new distribution boxes had to be clarified with the property owners and the civil engineering authority of the city of Bern.
