What WEG makes for data centers
public · HQ Brazil
WEG is a publicly listed company and based in Brazil. It appears on 4 parts of the AI data center — Large power transformers (345–765 kV) & substations, MV/LV transformers, Fans and motors and STATCOM and synchronous condensers — in the role of manufacturer. Those parts sit in Layer 6 — Facility cooling & HVAC, Layer 7 — Electrical: power distribution (grid to rack) and Layer 8 — Power generation & energy supply. Its shares trade on B3 (São Paulo) as WEGE3.SA. Large power transformers (345–765 kV) & substations is flagged as a supply constraint in this catalog.

Where WEG sits in the stack
WEG's placements in this catalog cover 4 parts, from layer 6 (facility cooling & hvac) to layer 8 (power generation & energy supply). One of them is tagged constrained, meaning a sourced shortage rather than a long lead time. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Large power transformers (345–765 kV) & substationsconstrained — Grid-scale transformers and switchyards that step transmission voltage down to what a data center campus can use, plus the substation civil works around them.
- Fans and motors — Fans and their drive motors that move air through dry coolers, adiabatic units, and cooling towers to reject heat to the atmosphere.
- MV/LV transformers — Step-down transformers that take medium-voltage distribution down to the low voltage used inside a building, available in pad-mount (outdoor, oil-filled) and dry-type or cast-resin (indoor) designs.
- STATCOM and synchronous condensers — Manufacturers of STATCOMs and synchronous condensers that stabilize grid voltage and provide reactive power support near large loads.

- This catalog places WEG on 4 parts: Large power transformers (345–765 kV) & substations (manufacturer), MV/LV transformers (manufacturer), Fans and motors (manufacturer) and STATCOM and synchronous condensers (manufacturer).
- Is WEG publicly traded?
- Yes — WEG is listed on B3 (São Paulo) under WEGE3.SA. Prices shown on this page are a nightly snapshot, not real-time, and nothing here is investment advice.
- Where is WEG based?
- Brazil, per the company record in this catalog.
- Who else makes large power transformers (345–765 kV) & substations for AI data centers?
- CG Power, GE Vernova, Hyosung Heavy, Hyundai Electric, Končar and LS Electric are also placed on Large power transformers (345–765 kV) & substations in this catalog.
- How well sourced are these placements?
- Every part→company placement carries a confidence tag. For WEG the mix is 4 inferred. "disclosed" means the company or a filing says so; "reported" comes from trade press or a reference-design list; "inferred" is a lead from the taxonomy with no citation yet. Treat reported and inferred as leads, not facts.
