5. Alstom

Alstom is a global transportation technology company whose historical power transmission and grid business has undergone significant corporate changes. Its former Grid business was acquired by GE in 2015 and subsequently became part of GE Vernova's Grid Solutions organization. The legacy Alstom Grid portfolio included high-voltage substations, transformers, switchgear, grid automation, protection, and transmission technologies. For market classification purposes, Alstom may therefore be listed among historical or legacy participants in the electric power transmission and distribution equipment industry, but current procurement research should distinguish its former grid assets from Alstom's present core transportation business. This distinction is important when assessing current suppliers and competitive market shares.

6. General Cable Corporation

General Cable Corporation is a major cable brand within Prysmian, following its acquisition by Prysmian. Prysmian currently operates General Cable as one of its three principal commercial brands alongside Prysmian and Draka. The business serves transmission, utilities, electrification, and power-grid applications through a broad portfolio of cable technologies.
