How to twist wires together ... and how we used to do it.

gkenyon

Was browsing though YouTube when I saw (but don't advocate) this vid entitled 'Awesome Idea! How to twist electric wire together!': https://www.youtube.com/watch?v=qHoyF4yKhjU

Well, reminded me of how I was taught to solder joints on power cables, and also part of a book I have in my collection, entitled General Electrical Engineering edited by Philip Kemp MSc(Tech) MIEE AIMechE (which is undated, but I believe is from the late 1940s or early 1950s).

I hope I'm permitted to post the extract of the two pages I had in mind, as it's a very old publication:

Certainly of interest, and shows there's a lot we used to know ... and how much depended on the skill of those who installed electrical equipment in days gone by.

  • How many of you were taught to use pliers to tighten the twist? I was taught not to because of the risk of damaging the strands.

  • in reply to Chris Pearson

    That depends on the size of the conductors you are twisting ... and perhaps why ... e.g. if you don't make the joint tight enough before soldering, and solder flows between the strands, it's not a good joint.

    I would use this type of joining... for a draw wire...

    Or even using an old cable to draw in a new one.
