Erience in creating mechanical equipment for northern hydroelectric stations

Abstract

1. To provide reliable and long-term operation of mechanical equipment under harsh climatic conditions at an air temperature below −45° it is necessary to develop and implement numerous special design and technological measures with consideration of the characteristics and experience of the installation and operation of structures already constructed. 2. It is necessary to heat-treat welded, cast, and forged parts, components, and structures intended for operation under harsh climatic conditions. 3. For mechanical equipment of hydraulic structures intended for operation in a macro-climatic region with a cold climate it is necessary to limit the use of articles in the “U” version and to outfit the equipment only with “CL” or “UCL” articles.
