Transmission Construction & Maintenance
Transmission, Built to Standard
Transmission is the backbone of the grid. GMB builds and maintains high-voltage lines and structures with the crews, equipment, and safety discipline this work demands.
What It Involves
The High-Voltage Backbone
Transmission lines carry power at high voltage over long distances, from generation to the substations that feed local systems. The work requires specialized crews, purpose-built equipment, and strict safety and coordination. GMB brings all three.
