Very basicly, such "transpositions" (physically transposed conductors) are intended for improved electrical balance along power line routes.

This and the other photos you have recently been viewing within this folder are from my former "Vintage Insulators" group on Yahoo. During December 2019, Yahoo pulled the plug on all of their groups. Before they did, I saved most of the photographs within the group's photo albums that I thought would be of interest. I will be periodically sharing them with you here on ICON. Most of these images were taken by and donated by Rick Shields. Thanks, Rick!
