Products for the US grid.
A focused portfolio of transmission, distribution, and substation equipment — designed to IEEE C57, ANSI, and NEMA. Manufactured at two industrial complexes, delivered under one US commercial interface.
Four products. Designed for the US grid.
Each product designed natively to IEEE C57 / ANSI / NEMA. Lead times across categories run 3–10 months — 2–3× faster than current US-market backlogs.
Power Transformers
Oil-immersed, up to 765 kV / 800 MVA. Step-up (GSU), step-down, autotransformers, phase-shifting, EAF, traction.
Cast-Resin Dry-Type
Epoxy-encapsulated, up to 12 MVA / 34.5 kV. Indoor substations, data centers, hospitals, high-rises, subways, offshore.
Distribution Transformers
Liquid-filled, 100 kVA – 5,000 kVA. Hermetically sealed, gas-blanketed, or conservator-type tank designs.
Reactors
Oil-immersed and dry-type, up to 500 kV. Shunt, current-limiting, noise-suppression.
Substation Equipment Integration.
Coordinated HV equipment packages supplied as single-contact deliveries — for utility, industrial, and renewable energy substation projects up to 765 kV.
Power transformers
Oil-immersed · two-winding · auto · OLTC/DETC

A package,
not a parts list.
ATEF Energy coordinates the HV equipment scope for greenfield substations, expansions, renewables interconnections, and data center campus feeds.
Single point of contractual accountability through specification, manufacturing, FAT, and delivery — your EPC handles balance of plant.
Specification
SLD review, equipment list confirmation, standards alignment, commercial proposal.
Manufacturing
Coordinated production across all equipment items, single PM, customer FAT at Baku or Hust.
Delivery + site
Logistics through US East Coast and Gulf ports, install supervision, pre-energization handover.
The full envelope,
on one page.
Voltage classes from 0.4 kV through 765 kV. Power ratings up to 800 MVA. Designed under IEEE C57, ANSI, and NEMA. 60 Hz across the line.
Two factories.
One portfolio.
Every product on this page is manufactured at one of two integrated complexes — ATEF Industrial Complex in Baku, or ATEF-Ukraine in Hust. Same engineering team. Same quality system.
ATEF Industrial Complex.
Nine specialized plants on a single industrial complex — cores, windings, tanks, insulation, cable, casting, structural steel. Operating since 1961.
ATEF-Ukraine, purpose-built.
30-acre complex configured to IEEE C57 / ANSI / NEMA from day one. New GEORG production lines, 765 kV capability. Commissioned 2024 — full ramp through 2026.
