UrBC, Yekaterinburg, January 16, 2019. Federal Grid Company United Energy Systems (FGC UES) upgraded the appliances at six power substations in Western Siberia. Last year, twenty air break and oil break switches got replaced with the most advances SF6 ones, FGC UES’s PR & Media Group for Western Siberia reports.

The company invested RUB 511 million into the modernization project to make the power supply to end users in Tyumen Region, Khanty-Mansiysky Autonomous Region, and Yamalo-Nenetsky Autonomous Region (where 3.6 million people live and major oil and gas companies operate) even more reliable.

‘SF6 circuit switches are an important part of the power substations’ system. These are meant for shutting the electric mains and the applicants down during an emergency. SF6 switch varieties are safer than air break and oil break switches; they are also more reliable, fireproof, and more environmentally friendly, and have a longer lifespan (twenty-five years at least), the company reports.

The upgrades took place at the 500-kilowatt Kholmogorskaya Substation and the 500-kilowatt Kustovaya Substation (capacity: 1,000+ MVA each). Both power substations are located in Yamalo-Nenetsky Autonomous Region and Khanty-Mansiysky Autonomous Region and are in charge of supplying electric power to Gazprom’s and Rosneft’s enterprises. They also ensure power transit for the entire territory of Tyumen Region’s north.
