Brief Description of Main Solutions
The cable line is intended for the reserve auxiliary needs transformer No.3 of Nizhnevartovsk GRES, which is to be connected to the 220 kV switchyard.
The reserve transformer is three-phase, double winding, with LV split winding of the ТРДНС 32000/220 type, 220/6.3-6.3 kV voltage, 32 МВ·А capacity, with the on-load transformer control.
With the aim to connect the reserve transformer to the 220 kV switchyard provided for is to construct the 220 kV indoor GIS with SF6 bays, with the 220 kV disconnectors.
