Shoes on a power line

Conductor clashing may be assisted by the following external forces:

Incorrect tensioning of the line during erection
High winds, or gusts during extreme storms or hot weather
Flora such as hazard trees breaking and falling onto wires
Fauna such as birds causing wires to sag and/or clash
Vehicles crashing into poles, causing poles to lean & wires to clash
Vandalism such as articles thrown onto power lines causing wires to sag and/or clash.
