Rosseti FGC UES (FGC UES, PJSC) has finished revamping Krokhalevskaya 220 kV substation in the Kemerovo region. New 35 kV switchgear has been installed, emergency control and backup power supply systems upgraded. The works cost 107 mn rubles. The project has improved the power supply to Berezovsky town district with over 47 thous. people, the Berezovskaya Central Beneficiation Factory and large coal mining companies: Chernigovsky, Kedrovsky and Rover open-pit mines, Berezovskaya and Pervomayskaya mines.

The upgrade included domestic equipment and was made within one year time. An outdoor switchyard had been used earlier to connect 35 kV network users at the substation. That switchyard was replaced with a state-of-the-art 35 kV switchgear located in a special heated modular building. This significantly increased the speed of equipment installation, protected it from external effects, and simplified its maintenance. The switchgear is designed to operate at temperatures between -60 and +50 degrees and wind speed up to 40 m/s.

The switchgear contains two feeders for voltage transformers and 11 feeders for state-of-the-art vacuum breakers. The use of vacuum units instead of oil-filled equipment has made the substation more reliable, firesafe, and environmentally friendly. 30 surge arresters have been installed to prevent damage to equipment due to voltage surges in the 35 kV network.

Relay protection and controls (RPC) have been modernized at the substation, and a new battery installed, as well as rectifier chargers intended to feed switching units, RPC systems, remote control hardware, alarms and warnings in case the substation's ancillaries are cut off from normal power.

The capacity of Krokhalevskaya 220 kV substation is 282 MVA. Among its consumers are large mining and processing enterprises of Severny Kuzbass, SDS-Ugol, Kuzbassrazrezugol and IMH.

Rosseti FGC UES upgrades power center of coal-mining enterprises in northern Kuzbass
