Crimping to extend cable length.

[Andy C]

Hi all and thanks for the help so far.

Re crimping, I have read posts regarding this before.
I have just seen those heat shrink solder connections.

I was going to use normal red and blue crimps then heat shrink each individual core then heat shrink over the whole T&E.

What are peoples opinions of the solder connection and is it better?

Thanks for any replies

A correctly made soldered connection is, in my opinion, the better option. I think it is too easy to make a poor crimped connection which isn't immediately obvious, especially when the actual connection is hidden in a plastic tube.

Insulated crimps of the type you intend to use never make a sound connection on solid core conductors. IMO they are only suitable for stranded cores.
Also I have reservations whether heat shrink provides the same rating of insulation as originally covered the cores.

Load of rubbish, as long as your using a decent quality crimper and crimps then the need to solder is completely negated. I often wonder how some people make money on this forum, fannying about with solder and several lengths of heat shrink. Most of them sound like the should work for the bleeding council. Talk about overthinking it, crimp-tug test- self amalgamating tape- job done.

The point is though insulated crimps of the type the OP is considering are NOT decent quality. If you terminate a solid core in these crimps it does not clamp the core fully because it cannot compress it, any movement of the core exerts considerable leverage on the crimp and the core will work loose.
I don't care if every single forum member says it's rubbish, they are wrong.

And then get some good quality heat shrink.

The crimping tool for insulated crimps doesn't form the crimp correctly around a solid core conductor.

An for those saying it's fannying about, I know I'd rather spend an extra min (that's all it would be) to do the job properly.

someone ought to invent a crimp where the conductors overlap, rather than be butted. this would ensure a better connection, IMO.

Could you use Wago connectors to extend a length of cable?

yes, but wagos have both conductors entering same side. OK in an enclusure bit looks naff in a CU. for that i'd use these:

Hmm, they look a bit bulky though Tel concept looks good though.

I already have a suitable crimper, but never thought of self amalgamating tape. That is quicker and less faff than shrink tube.

I had thought of that but the enclosure would then be buried in the wall. i wanted something maintenance free that didn't need an enclosure with all the extra chasing out.

they are a bit fatter than a yellow crimp connector, but much easier to use as you don't need to get crimp tool into a confined space, then find that 1 of the wired has pulled out when you're trying to crimp.

I already have that yellow crimper, looking at those crimps, they look hardy enough. I was thinking of double shrink tube, one on each conductor and one over the lot or is that overkill.
