The local REAs have been putting in twisted pair lines in the last
few years.
Does that help keep them from going down in ice storms?
It's not "twisted pair" - it's "triplex" and yes it is stronger than
individual wires, and they can't whip and hit each other either. The
neutral "carier" is usually a twisted steel cable and if not steel is
high strength aluminum alloy
It _IS_ twisted pair, not triplex. These are transmission lines, not
service entrance.
See the links philo posted altho here's the link to Southwire's product
page--

Not sure who's Dean's REC is; here's one near us (altho not us
specifically, they're just west). We started a number of years ago
after a massive ice event took almost 60% of our total transmission
lines down.

Yes, I was thinkingservice entrance
The Vr2 "compound" cables are wind and vibration resistant - and when
it moves it dislodges ice a lot faster than round cable.
