ABB's high-voltage/power-grids business was divested to Hitachi Energy (2020): new.abb.com/high-voltage 301s to www.hitachienergy.com/products-and-solutions. ABB is NOT an independent competitor in transmission-grade grid equipment — its tree is hitachi-energy.json. Kept as a stub so the atlas records the market fact without double-counting.
