Is this the service line you mentioned on the phone last time I was talking with you?
Surely looks like a sub-standard crimp or sealing job, as in moisture has got into the joint.
BTW, at which end of the service is the fuse?,
I expected to see one on the pole where the line-man is.
Bear in mind Mountain Electrician that these wires are insulated for Full Working Voltage, a hard hat would be a good idea, but not that necessary.
Nice to see he has the gloves and outers on though.
Note the lack of hair/grey hair with this guy, get with it if you want to be a Liney, it will take years off of your life!.
