Albertirsa–Zakhidnoukrainska–Vinnytsia Powerline
The Albertirsa–Zakhidnoukrainska–Vinnytsia powerline is a power transmission line between Ukraine and Hungary. It is a part of the former "Mir" transmission system between the Soviet Union and Comecon countries. As of today, it is the only 750 kV-powerline in Hungary and one of the few powerlines operated with this voltage in the European Union. History On 28 February 1974, the USSR, Bulgaria, Hungary, GDR, Poland and Czechoslovakia signed a cooperation agreement on construction of the 750 kV-line between Vinnytsia and Albertirsa, and substations Vinnytsia, Zakhidnoukrainska and Albertirsa. Construction started in 1975 and it went in service in 1979. Since the synchronization of the power grid of Hungary with that of the synchronous grid of Continental Europe (ENTSO-E) and because of economic reasons, the powerline went out of service in 1993, but was put in service again in 2002 after some new equipment was installed.

Overhead Power Line
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Since the surrounding air provides good cooling, insulation along long passages, and allows optical inspection, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy. Construction Towers for support of the lines are made of wood (as-grown or laminated), steel or aluminum (either lattice structures or tubular poles), concrete, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum (either plain or reinforced with steel, or composite materials such as carbon and glass fiber), though some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises. A major goal of overhead power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zhydachiv
Zhydachiv (, ) is a city in Stryi Raion, Lviv Oblast (region) in western Ukraine. It hosts the administration of Zhydachiv urban hromada, one of the hromadas of Ukraine. Local government is administered by the Zhydachiv City Council. Its population is approximately Zhydachiv lies on the Stryi River. It has two schools and one Ukrainian gymnasium. Name The city has historically had numerous name variants, reflecting its complex past, including and . It was mentioned for the first time in 1164 under the name ''Udech''. In documents from the 14th to 17th centuries, the city was referred to as Zudech, Zudachiv, Sudachiv, Zidachiv, Sidachiv, Zudechev and more. History The first written mention of the city dates from the year 1164. At that time the city was part of Galician Rus' and was an important trade center at the confluence of the river Stryi in Dniester with a stone church of St. Nicholas. Then called Udech, Zhydachiv formed from two settlements located at a distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hungary–Ukraine Relations
The modern bilateral relationship between Hungary and Ukraine formally began in the early 1990s, after the end of communism in Hungary in 1989 and Ukrainian independence from the Soviet Union in 1991. Since then, the relationship has been marred by controversy over the rights of the Hungarian minority in the western Ukrainian region of Zakarpattia, where 150,000 ethnic Hungarians reside. Hungary and Ukraine have embassies in Kyiv and Budapest, respectively, as well as consulates in regions with large minority populations. History Hungarian conquest of the Carpathian Basin As told by the ''Primary Chronicle'', the first interactions between the Hungarians and Kievan Rus' occurred towards the end of the 9th century during the Hungarian conquest of the Carpathian Basin, at Askold's Grave in Kyiv. During the Hungarian migration from the Ural Mountains to the Pannonian Basin, the Hungarians crossed the Dnieper river near Kyiv, the capital of Kievan Rus'. There, they stayed at th ...

Electric Power Transmission Systems In Ukraine
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...
