Broken Wire Analysis

07/15/2018 1:31 PM

Dear Sirs,

It appears that broken wire analysis in transmission line design is to confirm the type of loading in the transmission towers.

How is this done?

Best Regards,

When I was doing such stuff 30+ years ago: If this was a tangent pole, not an angle, if the connection was dead end, the full tension would be applied to one side of the arm or pole. If it was a suspension connection, the insulator length would swing out and add to the catenary length. This added length would make more sag and tremendously less tension to be supported by the arm/pole. Of course there would be impact and torsion forces, but we found them to be ignorable on the pole, but it would be a large load on the arm. I seem to remember one that was 40000 pounds on a 20 foot arm. The utility should, of course, provide you with the normal loads and the loads under wind, icing, and wind plus ice conditions.
