they are turbine generators in hydro electric power plants - they are live buildings; the floor and walls are resisting all of the torque from the generators and the forces exerted by the water flowing through the building, and the machines are vibrating at 1 mm/s velocity or about 4/1000" displacement. So it isn't completely stationary, everything is just kind of humming and rumbling - unless there is a short circuit out on the power system and then massive forces are exerted on the generator and power conductors, or if the machine becomes disconnected from the power system and has 10 MW coming in and 0 MW going out it tends to speed up quite rapidly and shake a bit more - but for the most part I can't imagine any conductors wearing through their insulation, ever. No wires are ever exposed to sharp edges.
