Aerial tree trimming planned for central Wisconsin

Helicopter, air saw to be used along transmission line

PEWAUKEE, Wis. – A helicopter and heavy-duty air saw will be used this week and continue through mid-March to trim trees along two 345,000-volt lines from Stevens Point to Appleton, as well as along a 138-kV line in Wood and Juneau counties.

American Transmission Co. has contracted with Aerial Solutions, Inc. to manage vegetation growth along its transmission line corridors. This work will be accomplished using an aerial power saw with rotary blades that is suspended from a helicopter on a 90-foot vertical boom.

The aerial saw has been highly efficient when compared to the work of ground-based crews. “It takes just a few hours for an aerial saw to complete what typically takes ground crews several days to accomplish,” said Adam Helminiak, ATC senior vegetation management specialist. “However, the aerial work is weather-dependent and it could take up to several weeks for the saw to complete the vegetation maintenance along the transmission lines.”

Managing the growth of trees and other vegetation near high-voltage transmission lines is important to help ensure public safety and electric system reliability. ATC performs routine vegetation management on its 9,540 miles of transmission lines in five-year cycles.

Note to editors: Landowners in proximity to the transmission lines scheduled for this work have been notified of the work via mail. Maps indicating the planned aerial saw work can be found on our website. Work on section WERWL41 is scheduled first, followed by work on NAPL71 and X-43. Video footage of similar vegetation management work can be found on our YouTube page.
