750 kV line Rzeszów – Chmelnyzkyj

Bracing masts of the 750 kV line with bundled conductors

The 750 kV Rzeszów – Chmelnyzkyj line is the only 750 kV line in Poland and is one of the few high-voltage lines in the European Union that can be operated with this voltage. It was built in the 1980s, put into operation in 1985 and leads from the Widełka substation (north-northwest of Rzeszów at 50 ° 11 ′ 49 ″  N , 21 ° 52 ′ 19 ″  E ) to the Chmelnyzkyj nuclear power plant in Ukraine . The 750 kV line Rzeszów – Chmelnyzkyj with a length of 395 km has a single circuit and as a bundle conductorExecuted conductors. The rated current per conductor is 1500 A, and a total power of 1300 MVA can be transmitted.

Rope-anchored portal masts are used as support masts . The construction of the guy masts is unusual . They consist of a free-standing mast for each individual phase, with the isolators attached directly to the mast. The current loop consists of a conductor cable that is routed around the mast via an insulator that is attached to a traverse or the secondary mast.
