The decision to build this powerline was made in 1977 and it went in operation in 1985.[1] The line went out of service after Poland joined the synchronous grid of Continental Europe (UCTE).[2] However, there is a plan to re-activate this line after 2010 by constructing back-to-back station on the Polish end of the line. The first report on the back-to-back station was prepared already in 1995.[3]
It has a length of 395 kilometres (245 mi), of which 281 kilometres (175 mi) in Ukraine and 114 kilometres (71 mi) in Poland.[1] It runs from Widełka substation near Rzeszów in Poland to Khmelnitskiy Nuclear Power Plant in Ukraine. It is the AC line, which has a single circuit. It can transfer a maximum power of 1300 MVA.
As pylons guyed portal pylons are used. Strainers are from special design. They consist of three free-standing lattice towers each carrying one conductor. Each strainer tower has a crossbar at which the conductor is led around the structure on a huge insulator.
