Slight damage in armoured cable

[Jupiter01]

Not sure how well you can see it in this picture but noticed that this has a slight nick. Can I tape it up or does the whole length need to be replaced?

It’s armoured cable.

It’s armoured cable.

Yes but is that damage acceptable? You can see the steel wires inside it

You can use Wrap around heat shrink to repair that.

It takes a long time for SWA to rust through so if the damage is repaired with a water tight repair, like self amalgamating tape then as long as tested at the prescribed intervals, there is not really a problem.

Use heat shrink tubing

Slid over an armoured cable which is installed and glanded at each end?

Split and overlap

And when you shrink it, what happens?

Self amalgam tape would be better but not really ideal, the whole run should be replaced.

A few years back someone did an experiment - drilling a hole with a fine drill thru the cable, apparently it ois possible to drill/stake a pin thru such and miss or only lightly come into contact with the armor yet pierce the live conductors inside - SWA is not quite the bees knees of protection in all cases apparently, the results astonished him apparently.

Brill against spades and diggers though!

Denso tape??

That doesn't look installed and terminated to me.......

I rather hope not on all those sharp stones!

I assumed that we could see neither end, because if this is one end:

he wouldn't need to be asking about taping it up, as he'd know he could easily slide a few pieces of heat-shrink over it.
