What are the critical safety considerations when working on a 275kV overhead line?

2025-08-13

Working on a 275kV line is inherently dangerous and requires an unwavering commitment to safety. The following are non-negotiable safety considerations:

  • Minimum Approach Distances (MAD): The high voltage creates a significant arc flash risk. Workers must maintain a strict, legally mandated minimum approach distance from all energized conductors. This distance is much greater than on lower voltage lines.

  • Live-Line vs. De-energized Work: Projects are either performed using live-line methods with highly insulated tools and equipment, or the line is completely de-energized and grounded before work begins. Our tools are designed for both scenarios, but the correct procedures must be followed without exception.

  • Training and Certification: All personnel must be highly trained, certified, and experienced in EHV work. Using the right tools is only one part of the equation; having the skilled personnel to operate them safely is paramount.
