Had a chat with a chap who has been engaged to sort out some sound/mixing desk setups at a place I am currently working on. He said that although most audio comms these days are done via CAT 6 he is still insisting upon a 30 core cable to be run for analogue stuff. It's not my bag really but since he proposed that the cable be run through one side of the ballroom at high level I told him that he needed to bear in mind the potential for premature collapse in the event of a fire and that he needed to contact the cable maker for the specs on cable support spacing for metal clips. He said he'd never heard of this before, which made me wonder how many night clubs and other performance venues he and his company had served in a similar manner.
Any idea what the weight of a 30 core commes cable (that is all the info I have on it) weighs? Or what a typical clip spacing for such might be? Length of run will be some 50 metres or so, at least 25 of which will be run horizontally on brickwork at some 25ft or more in height.
