You probably don’t pay much attention to the thousands of utility poles found throughout Big Country Electric Cooperative’s service territory, but did you know these tall structures are the backbone of our distribution network?
Strong, sturdy utility poles ensure a reliable electric system, which is why we routinely inspect the poles on our lines. Throughout the year, our crews and contractors check poles for decay caused by exposure to the elements. They know which poles are oldest and conduct inspections through a rotational process. Typically, a standard wooden distribution pole is expected to last more than 50 years.
Occasionally, poles need to be replaced for other reasons besides decay and old age. Weather disasters, power line relocation and car crashes are potential causes for immediate replacement. When possible, Big Country EC communicates when and where pole replacements will take place so that you stay informed of where crews will be working.
Here’s a quick breakdown of how crews replace a utility pole:
When a pole needs to be replaced, crews will start the process by digging a hole, typically next to the pole being replaced. The depth of the hole must be at least 15% of the new pole’s height.
Next, the new pole must be fitted with bolts, cross arms, insulators, ground wires and arm braces—all of the necessary parts for delivering safe and reliable electricity. Crews then safely detach the power lines from the old pole. The new pole is then raised and guided carefully into position, and the lines are attached, leaving the new pole to do its job.
So the next time you come across a co-op crew inspecting or replacing a pole, use caution and know that this process ensures a more reliable electric system for you, our members.
