How engineering expertise and installer readiness supported a complex underground grid modernization project in the Grand Canyon

When every connection must work in one of North America’s most demanding environments, preparation is critical. With no road access and materials transported by helicopter, this underground grid modernization project required careful planning before installation even began.

TE Connectivity supported the project with medium-voltage cable accessories, application engineering, project-specific splice configurations, and hands-on installer training to help crews prepare for reliable, consistent field execution under demanding site conditions.
