History

Construction of a 750 kV powerline from Ukraine through Romania to Bulgaria was agreed on together with construction of the South Ukraine Nuclear Power Plant. The agreement was signed in Moscow in 1982 by the electrical industry ministers of the Soviet Union, Romania and Bulgaria. The powerline started operating in 1986 and it was completed in 1988.[1]

Route

The powerline starts in Bulgaria at Vetrino (Suvorovo) substation near Varna and runs northward. In Dobrudja it crosses the border between Romania and Bulgaria and terminates at Isaccea substation in Romania. From there the line crosses Danube River, which forms the border between Ukraine and Romania in a 938 metres long span on two 118 metres tall delta pylons situated east of Isaccea and runs than to Yuzhnoukrainsk substation situated just north of South Ukraine Nuclear Power Plant.

Hereby it crosses at least four times the border between Moldova and Ukraine. However, there is and was no branch to the power grid in Moldova, although it passes Vulcăneşti substation.

Description

The used towers are designed for carrying a single circuit in a single level. As conductors bundle conductors of 4 ropes are used. Nearly all suspension towers are portal pylons, most of them guyed, but also several free-standing. The free-standing portal pylons carry the conductor in the middle on a V-shaped insulator, while the outermost conductors are as at the guyed suspension towers carried by a normal suspension insulator. As strainers triple towers are used whereby a fourth tower is required for strainers without or with less direction change for keeping the required distance of the outmost conductor to the tower. Also transposing towers are implemented as monopolar towers whereby two additional towers are required.

Current state

The section between Vetrino and Isaccea is since the synchronisation of the Romanian power grid with that of Western Europe, which took after 6 years of trial operation finally take place in 2003 , operated with 400 kV. The section between Isaccea and Yuzhnoukrainsk is since the synchronisation of the Romanian power grid with that of Western Europe not in use and scrapped in most parts.
