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.
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.
Baku Industrial Complex
Nine specialized plants on a single industrial campus — vertical scope from raw steel processing through factory testing, under one corporate roof.
ATEF-Ukraine Facility
30-acre site purpose-built for IEEE C57 production. GEORG core lines and HighVolt / OMICRON testing, configured for US-standard output from day one.
Nine specialized plants. One industrial campus.
Each plant has dedicated equipment, personnel, and quality systems — sharing centralized engineering, design, testing, and logistics infrastructure.
Power Transformer Plant
Large oil-immersed transformers up to 500 kV / 800 MVA
ATEF Transformer Plant
Distribution and medium-voltage transformers
ATEF Elektromash Plant
Switchgear and electrical equipment
High Voltage Equipment Plant
HV switchgear, reactors, instrument transformers
Metal Construction Plant
Transformer tanks, conservators, structural elements
Metal Casting Factory
Castings for transformer components and structural fittings
Cable Manufacturing Plant
Power cables and continuously transposed conductors (CTC)
Mechanical Processing Plant
Machined components and precision parts
Insulation & Component Plant
Windings, insulation systems, polymer and epoxy insulators
Every key component, in-house. No supplier dependency.
Quality, lead time, and specifications enforced at every stage — not delegated across external supplier networks.
Core processing
Grain-oriented electrical steel cut and stacked. Laminations 0.18 – 0.30 mm thickness, processed for minimum no-load loss.
Winding
Primary and secondary windings produced in-house. Continuously transposed conductors (CTC) for high-MVA on dedicated lines.
Tank fabrication
Tanks, conservators, radiators, and pressure vessels welded and assembled in the Metal Construction Plant.
Insulation systems
Kraft paper, pressboard, polymer, and epoxy insulators. Custom HV geometries produced internally.
Cable production
Power cables, control cables, and CTC produced at the Cable Manufacturing Plant.
Metal casting
Bushings, terminal blocks, mounting fittings, structural components cast at the Metal Casting Factory.
Mechanical components
Machined parts, precision fittings, and assembly hardware produced at the Mechanical Processing Plant.
Nine stages, from spec to commissioning.
Specification & Design
Engineering review of US-spec requirements, core cutting, and primary winding.
Manufacturing & Assembly
Vapor-phase drying, active part assembly, tank fabrication and oil filling — the bulk of lead time.
Testing, Delivery & Commissioning
IEEE C57 acceptance testing, ocean freight to US ports, and on-site installation supervision.
Tested to 765 kV. Certified by KEMA & CESI.
Type-test reports per IEEE C57 issued under every US contract — standard scope.
Winding resistance · Ratio & polarity · Short-circuit impedance · No-load & load loss · Dielectric (applied + induced)
Temperature rise · Lightning impulse (full + chopped) · Switching impulse · Short-circuit withstand
Capacitance & tan-delta · FRA · Partial discharge (≤ 5 pC) · Sound level · Insulation resistance & PI
Specification reviews, capability discussions — engineering on call.
Single-line diagrams, RFQ technical clarifications, factory acceptance test planning — engage early to reduce project risk later.
