What does orange ribbon around power pole mean?

newsherald.com - What are those orange things on poles? - Panama City News-Herald

Collin Breaux

cbreaux@pcnh.com

BAY COUNTY - Drivers going down U.S. Business 98 in Bay County — particularly near 5th St. and East Avenue — have probably noticed a lot of orange, from the cones in the road to the coverings on the lines as crews work on utility poles.

The natural question is, what is going on?

"The orange things ... are safety protection devices we use to insulate equipment as we work to change out the poles and wires. Safety is a core value for our company and when we work we want to ensure the safety of our employees and our customers," Gordon Paulus, Sr. Communications Specialist with Gulf Power, wrote March 5 in an email. "This project, which goes about a half-mile on U.S. Business 98 between East Avenue and Sherman Avenue, then south on East Avenue to Cherry Street, is to upgrade poles and wires that improves our grid resiliency to deliver greater reliability to our customers began before Hurricane Michael, and due to the extensive work we have done in storm recovery, the completion of the work was delayed. Our current schedule indicates the project should be completed this week."

Similar work has been spotted along Beach Drive in Panama City.

Drivers will notice that as the poles are changed out, some of the older ones appear to be cut in half with the bottom portion left in place, particularly at intersections where lines need to cross the road.
