en plein portée

[chapteryx]

In relation to high voltage power lines, I have a phrase that I do not understand, and hope that an electrical engineer might chip in ...

"Conducteurs nus rompus en pleine portée"

Does "en plein portée" mean "in full use" ?
Or does it have some other domain-specific meaning related to conductors ?

TIA

Sounds to me as if the cables broke "mid-span".

Sounds fair enough to me - I hadn't thought of the "range"/"coverage" => "span" type meaning of portée - thanks very much.
