Bagakhangai — 660 MW Thermal Power Plant Temporary Supply Line & Substation

A complete electrical power supply infrastructure was established for the construction-phase temporary power supply of a 660 MW thermal power plant under construction in Bayan soum, Tuv province.

The scope of work included:

• Supply and installation of 9 anchor towers and 82 reinforced concrete intermediate towers for the 35 kV line
• AC conductor stringing, stay wire tensioning, and insulator clamping for 13.3 km of 35 kV overhead transmission line
• Installation of 2 complete 35/0.4 kV, 2,000 kVA transformer assemblies
• Supply and installation of 2 complete 0.4 kV distribution switchgear sets
• Supply and installation of 2 complete 0.4 kV enclosed switchgear E-houses
• Supply and installation of 35 kV circuit breakers, disconnectors, surge arresters, and portals
• Supply and installation of relay protection panels for each transformer
• Cable tray installation, secondary circuit cable pulling and termination
• Earthing system and lightning arrester installation
• Testing and commissioning

This complete electrical infrastructure project provided reliable power supply for construction operations at the 660 MW thermal power station.
