What the shared parts are
- 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.

Questions
- Do ABB and WEG compete?
- In this catalog they are both placed on 3 of the same parts, across 3 layers: Fans and motors, MV/LV transformers, STATCOM and synchronous condensers. Sharing a part does not mean selling the same product to the same buyer, so read each row's product note.
- Which has more placements, ABB or WEG?
- ABB has 16 placements and WEG has 4. Placement counts reflect how thoroughly each company has been catalogued as well as its real breadth, so they are not a ranking.
Generated from the catalog's part-to-company table. Each placement is tagged disclosed, reported or inferred; see sources & method. Neither company is endorsed or ranked here.
