Re: a short section of heat shrink tubing as a damping sleeve ?

I suspect that the vibration a 3AG type fuse element may be undergoing is caused mainly by the current it is passing rather than from airborne or structure borne vibration. After all, the fuse & holder are ensconced inside an equipment enclosure which should block most of that type vibration. I have seen 440v insulated transmission cables with a 4-5 ft. "drip loop" from transmission pole to building entrance head whip violently upwards above the pole when a sudden, heavy power draw was made. I suspect that the same effect, in microcosm, may be happening to the fuse element. The fact that the fuse element appears to be wound around a fabric of some sort and is also stretched taut should tend to reduce that effect.
