"Melted" overhead wire sheathing

#1

Curious, never seen this before - what would cause the wire sheathing distortion like this at the connections? Bad connection/crimp on that side and overheating? TIA.

High resistance at the splice.

I agree it looks like overheating from a poor connection. Could be that the connector corroded over time. Nice find. :sunglasses,
