UrBC, Yekaterinburg, August 19, 2016. Rosset’s Federal Grid Company United Energy Systems is about to complete the upgrades of its 500-kilowatt Kurgan Substation, which is expected to make the Russia-Kazakhstan power supply considerably more reliable; the supply system involves a 500-kilowatt international OHTL Kurgan-Aurora. The upgrades will also benefit the power supply in Tyumen Region, with its 500-kilowatt OHTL Kurgan-Berkut, the company press service reports.

The substation gets all of its older switches gradually replaced with the modern sulfur-hexafluoride circuit breakers. The new equipment is better suited for various climatic conditions, is more reliable and fire-safe, needs repairing less often, and takes up less space.

The upgrades also involved replacing the electro-mechanical breaker control automation system and protection-system terminals as well as cable tracks, their concrete trays, and earthing rings.
