A powerline repairman showed off the mechanisms used to keep the power supply to a town in Greenland running, as cables are run through to shatter the ice forming on them.

This amazing clip from near the town of Nuuk in western Greenland, filmed on September 4, 2018, shows how the cables run from 1000m above sea level to a height of 5400m, and how vibration dampers have to be installed to keep the cables intact.
