Home/Manufacturing

Two industrial complexes.
65 years of practice.

Production from nine specialized plants in Baku, Azerbaijan, and a new 30-acre facility in Hust, Ukraine — vertically integrated from steel processing to final bushing assembly.

Projects Delivered 500+ Across US & global grids
Plants 9 Single Baku campus
Workforce 2,500+ Engineers · technicians
Peak Voltage 765 kV Up to 800 MVA / unit
Standards IEEE C57 ANSI · NEMA · IEC 60076
02Manufacturing Footprint

Two parallel complexes. Designed for production redundancy at the manufacturing level.

Independent supply chains, currencies, and logistics corridors per site — continuous capacity even when single-site disruptions affect single-plant competitors.
