Badly coiled cables

[Bryson]

It wishes it was a telephone cord.

 

I've seen the same thing on similarly aged Allen & Heath PSU cables. Maybe it's the same type of cable.

Must just have been one bad batch of cable. We've still got our old Soundcraft Venue desk with one of those power supplies, and our cable hasn't gone like that. The outer jacket is black, if that makes any difference.

Similarly I not seen this happen on a dozen or so, both black and grey.

 

As I wrote earlier, I'm not disputing the faulty cable issue, I've simply not encountered it. There seems to be a few now quoting Van Damme admitting the fault, I trust they replaced the faulty lengths.

One of the Arena's we crew for has a house 125A 3 phase cable just as coily.

Which has obviousely been withdrawn from service when it failed its PAT.

Still in service, and being used today.......

For what reason?

The Parallel Asymmetry Test? I think it should be obvious why it's failed if it's not perfectly parallel along its full length.

Visual test

 

Any one using a mains cable in that condition needs their head testing. I'd happily call in the HSE if I saw a big mains cable in that condition being used in a public venue.

I was given an old 4 gang extension lead with Pirelli H07 rubber cable that had turned into a telephone cable. That went in the cable bin!

As long as it was between 8:30 am and 5pm Monday to Friday, but not until 10am on a Wednesday 'cos that morning is staff training. Oh, and HSE aren't the enforcement authority for theatres or other leisure premises.

Im surprised I survived the 70's considering every were you went these sort of things were hanging over the dinning table

I'm still completely lost as to why to would fail a visual test. Damaged cable, worn cable, cable with insulation cracked or compromised, but come on - curly cable is just a pain - I just don't see any electrical danger - the visual inspection surely is not based on if the cable is dirty, or covered in sticky gaffer residue, or has a shape that offends - the visual inspection is looking for faults, and curly cable is a fault that doesn't compromise anything apart from length and convenience. Could be a horrible trip hazard of course, but that isn't a PAT failure.

+1. In my previous full time position, I would have considerered such curlyness to have been grounds for 'retiring' a cable, but purely from a 'maintaining percieved standards' point of view, rather than a safety point of view.

I think the issue is that this could be an indicator of severe stress to the conductors. Broken strands are very difficult to detect with resistance methods so it possible that your e.g. 6mm flex is now only 1mm in places. Just my £0.02 worth.
