Completed works
- 220 kV outdoor switchgear (OSG) for power supply of rectifier‑transformer substations.
- 220 kV OSG equipment – disconnecting switches, switches, excess‑voltage suppressors, current and voltage transformers (ALSTOM)
- Rectifier‑transformer substation (RTS‑9) for (DC) supply of pot line units. RTS are equipped with converting units (5 load‑center ALSTOM units)
- Rectifier‑transformer substation (RTS‑9) is powered from the 220 kV open distribution system by overhead cables.
