ABB has opened a new plant and test facility in Poland for BORDLINE CC750_DC_3kV, a powerful compact converter for Electric Multiple Unit (EMU) trains in DC grids.

The 56 BORDLINE CC750_DC_3kV converters provide reliable and smooth transport in 14 regional trains from Stadler Rail of type FLIRT in the regions of Mazovia and Silesia.

The Polish railways network consists of around 19,600km of track, of which the vast majority is electrified using a 3kV DC overhead line system.

A 3kV DC line voltage is the most widespread electrification in Poland, Spain and Italy, and for many other important rail networks in central and Eastern Europe and the Southern hemisphere, the company said.
