Project Spotlight: Emergency Repair of 138kV HPFF Transmission Line

Published on Back To Index

InfraSource crews were recently mobilized to respond to an emergency leak on a high-pressure fluid-filled (HPFF) underground transmission line. The situation required immediate action to prevent further damage and restore service safely and efficiently.

The team executed both civil and electrical scopes of work, including excavation of freeze pits, installation of protective structures, and restoration of the transmission line. Electrical crews performed freeze operations, welded sleeve repairs, valve replacements, and fluid refills to bring the line back to full service.

Throughout the project, InfraSource coordinated closely with local businesses to minimize disruption. Custom signage was installed to maintain safe access to nearby storefronts and parking areas.

This project demonstrates InfraSource’s ability to respond quickly to critical infrastructure needs while maintaining safety, precision, and community awareness.
