Grängesberg is a village ( Tatort ) in the municipality of Ludvika in southern Dalarna in Sweden .

History of the iron ore mine

Grängesberg was shaped for centuries by its iron ore mine , which was in operation from the 16th century until 1989. In 1990 the last ore railway went to Oxelösund on the Baltic Sea for export and the ironworks there.

Grängesbergsbolaget (founded in 1896 as Trafik AB Grängesberg-Oxelösund ) was Sweden's largest mining company and for many years owned one of the largest iron ore fleets in the world. The iron ore mines of Grängesberg had the richest ore deposits in central Sweden. Until the beginning of the twentieth century, the iron ore was extracted in open-cast mining, and later in shaft mining. During the 1970s, the site had to be rebuilt because the subsoil was undermined by the mining. The new center was rebuilt around 500 meters to the east. The old center, popularly known as “Gamla Grängesberg”, has partially collapsed into the old pit.

History of AC power transfer

The place Grängesberg became internationally known at the end of the 19th century for the world's first commercial transfer of three-phase alternating current . The overpass was between the hydroelectric power station near the village of Hällsjön and Grängesberg. It was a distance of 12 km with a voltage of 9500 volts. The facility was to provide the mining area with electricity for lighting and motors. This was a previously untested method, because previously they had mechanical power transfer systems such flatrod system used.

The largest employer is the private brewery Spendrups . With the train station Grängesberg the place has a rail connection. Sights include the Railway Museum Grängesberg and Cassels Donation, a concert hall, the construction of which was made possible in 1898 by a donation of 250,000 kroner from the German-English financier Sir Ernest Cassel .
