Brief Description of Main Solutions

The 330 kV switchyard is to be made based on the scheme «the transformer - busbars with the lines connection based on the 1 ½ circuit breaker scheme» with the circuit breakers three-row arrangement. For connection of two 330 kV OVL leads-in and two 330/110/35 kV auto transformers of 200 МVА capacity each.

The 110 kV switchyard is to be made based on the scheme “One working busbar system sectionalized by the circuit breaker”. Connection of each АТ via two circuit breakers, with no bypass busbars, with eight 110 kV lines and the perspective extra eight reserve lines connection possibility.

The construction was completed in 2012.
