Must crimped cables be shrink-wrapped or covered in insulating tapes or something similar?

Thanks

It's considered good practice to do it. I wouldn't use insulating tape though, it will eventually fall off!

The crimp itself is insulation enough and when crimping singles in conduit or trunking then I don't double insulate. When dealing with T&E then I'll stagger the crimps and then heatshrink over the lot.

Welcome to the forum by the way! :D

My boys beg to differ Mr Sworld.

(As long as it is done correctly)

And if anything, it can be rather awkward to remove.

Thank you Mr Sworld

Having only recently qualified and completed the electrics in my rather large extension and having made numerous changes to the current electrics, I think I've learned more doing this than I did on my course - in a practical sense.

"shrink-wrapping" and "crimping" had never been mentioned and I only found out how to do the crimping because I asked. Now all I need to do is find out how to shrink wrap!

The site is proving to be invaluable reading... :) , it's just a shame that I only seem to get a chance to get online at these ungodly hours:_|

Cheers

Nat

When using insulated crimps, I offset them and then wrap the joint in several layers of self amalgamating tape.

When using uninsulated crimps on larger cable sizes I use glue lined heat shrink (from Maplins and elsewhere) around each crimp before using self amalg.

If the joint is to be exposed or outside, I'll put on an extra layer of heatshrink over the lot. Also make sure the cable is supported each side of the joint so there's no stress on the joints.

I got one of these a few weeks back,

the dogs dangly bits, and cheap too.

while we're on it, anyone got a suggestion for shearing 35mm SWA??

Ive tried ordinary cable shears but too much pressure for them.

I have about 200m of it to take out above a suspended ceiling and no room for a hacksaw, I need it in about max 2m lengths or smaller so loadsa cuts.

No, no, no. Stick to the good old fashioned, Hacksaw.

That's the way I do it. :)

In the office again.
PMSL @ Apache (Moo) :D :D - even though they`re NOT talking about pliers!!!

Ordinary SWA Admin - I`d also be at it with hacksaw. :)

However - BIGGIE SWA - angle grinder would be my weapon of choice mate. If you`re competent with one, you can even prep the end for glanding!!!!! :D
