Reference of Vilyuiskaya HPP cascade named after E.N. Batenchuk
On 15 June 2018, we received reference from Vilyuiskaya HPP cascade named after E. N. Batenchuk about the successful operation of Izolyator high-voltage bushings in the severe climate conditions.
Vilyuiskaya HPP named after E. N. Batenchuk is a hydraulic power plants complex in Russia, located on the Vilyui river in Sakha Republic (Yakutia). Most of the erection works were completed in the Soviet period when the cascade construction was associated with the industrial development and tapping resources of Yakutia. The cascade is the only guaranteed power supply ensuring uninterruptible delivery of electricity to the Western Yakutia. Vilyuiskaya HPP named after E. N. Batenchuk is part of Yakutskenergo PJSC.
Herewith, we confirm that beginning from 2012, our company purchased high-voltage bushings with polymer external insulation, made by Izolyator plant: 23 pcs of GKLP III-90/252/2000, IVUE 6862353.235.
These bushings were installed on an indoor switch gear ZRU-220 of HPP-1 of Vilyuiskaya HPP cascade as a replacement of GMLA-90-200/1000 U1, manufacturer’s drawing 415-0-0. We have not registered any faults and have no complaints about operation of the equipment in severe climate conditions (temperature range from +40 to –65 dg Celsius).
