Damaged Core - what to do ?

[shelby3]

I've slightly damaged the live core of some SWA. All terminated successfully, but ended up slightly nicking the brown core. Not deep enough to penetrate through to the copper.

For now I've just covered it with insulating tape.

Any recommendations ?

Helimen sleeves, shrink sleeve, or any other sleeve depends where it is in some cases epoxy resin shrink sleeve.

Sorry - I didn't provide enough info.

The issue is inside the junction box where it terminates in the garage. I have used a plastic enclosed box to terminate the SWA, which then runs T&E tails to the CU in the garage.

Is it acceptable to just sleeve it, and not use heatshrink. It is the LIVE core.

Thanks

How have you earthed the armour in the SWA ?

 

[shelby3]

I certainly have. Thanks to the wiki pages on this site, and some practice with some off cut of cable. I earthed the armour from source (house) via a fly lead to the earthing block, and at the destination point (garage) aswell by joining the earth from the T&E. (No Gas/Water in the garage).

So you used

or

As for the cut in sleeve, tape will suffer from wet and heat weathering and will fail.

I'd use a 2 part glue / expxy and butter that in and around the damage.

The other alternative (and best) would be to pull some slack and re-do the split and term 4" down the cable. That does depend on spare / slack being available.

I used the top one. Crimped the earth cable and bolted it into the hole.

Thanks for the advice. I do have some slack, but that's last chance slack, and if i mess that up, i really am stuffed !

Good work

If the bolt is exposed to the weather, a tiny bit of grease / vaseline on it will help stop it oxidising.

could it be easier to move the adaptable box and extend the T and E that way you can find more slack
