So, why is that insulator actually dangling?

  I assume it’s because the cable it insulates needs to sway in the wind, otherwise you’ll get shearing on the cable itself as it sways between completely fixed points? Alternatively it might be made this way because the cable angle is variable (depends on terrain topology) so a fixed-angle insulator would require every single tower to be customised when installed. A 100y mtbf seems pretty good by comparison, you’d reasonably assume the component would be replaced long before that.
