In preparation for the heating period of 2019-2020, Rosseti Centre Belgorodenergo has almost completed the repair program for the current year. As of 15 October, 2,246 km of overhead and cable power lines of 0.4-110 kV (101.7% of the plan for the year), 728 transformer substations of 0.4/6-10 kV (100%) were repaired. 585.2 hectares of routes along power lines were cleared from trees and shrubs and expanded. 332.2 million rubles were allocated for the implementation of the program.
At 110 kV substations, power engineers overhauled 277 circuit breakers and 194 disconnectors, thereby increasing the reliability of power supply to large and socially significant consumers: Belgorod Regional Clinical Hospital of St. Ioasaph, Children’s Regional Hospital, City Hospital No. 2 of the city of Belgorod, BSTU named after V.G. Shukhov, enterprises of “Belgrankorm”, “Kryukovsky pig farm”.
In order to increase the reliability of power supply to Rakityanskaya Central District Hospital, Prokhorovsky Feed Mill, agricultural enterprises of “Hohland Russland”, “Avida”, “Oskol Milk”, “Belgorod Dairy Farms”, measures were taken at a number of substations to replace 479 sets of obsolete porcelain insulation with polymer.
To increase the protection of equipment from switching and lightning surges 36 new arresters were installed at the substations “Purification”, “Kurasovka”, “Kochetovka” and “Prilepy”; bushings of two sectional switches and one 35 kV transformer bushing were modernized at the 110 kV substations “Krasnogvardeiskoye” and 35 kV “Radkovka”; 8 bushings of switches and 129 sets of supporting insulation were replaced at the 35 kV substation “Zapadnaya”, on which reliable power supply of the Gubkinsky meat processing plant and several other enterprises depends.
Overhaul of power lines with replacement of poles, insulators and clearing of routes along the lines was carried out on 26 overhead lines of 35-110 kV, including 110 kV Conductor “Novy Oskol - Serebryanka” 26.8 km long, the 110 kV Conductor “Konshino - Golofeevka” (47.1 km), the 110 kV Conductor “Frunzenskaya - Mayskaya” (24.9 km), the 35 kV Conductor “Irrigation - Urazovo with a tap to the Urazovo state farm” (61.9 km), the 35 kV Conductor “Krasnogvardeiskoye - Razdornoye” (27.1 km).
This year, the program for maintenance and repair of electric grid facilities is 87% completed by Belgorodenergo’s personnel, without involving contractors.
