get another long rope attached to existing rope with a knot that would increase size of rope ( reef knot ? ) and pull through duct and back to see if it snags anywhere before attaching cable

CABLE PULL FAILURE
Background
Recently on a construction site in Perth’s CBD the electrical contractor was in the
process of pulling a 50mm Diameter fire rated cable from basement 2 to level 21.
The pulling “sock” which was attached to
the end...
it came from a rep. from cable manufacturers it also helps with the stress/stretching of cable ,also recommended in australia after cable fell 16 floors in a riser (is your mind still boggling)
pulled long hv cables used long stocking then drilled 2 holes through cable sock and cable (at different angles )then bolted sock to cable and taped up well
have you tried exposing cable outside of extension and give it a good pull to see if it moves if its only 8mtr you might be able to pull enough to see damage (unless its cast in concrete)
Just back from spain ,hot water packed in (rep said just let it run it will be ok ) found plantroom not locked? no cover on immersion novel way of wiring maintenance guy thought it ok (or i think thats what he said ) heater tripping rcd out and taking all solar out with it
