information on how to twist two conductors without wire unwinding?

Question

wire lengths of 20 to 30 feet awgs of 14, 12, 16 in
pairs to be twisted for noise reduction. i need a process to twist wire or a small machine

Answer 1

I had a low-budget engineering friend who faced that problem.

He put one end of the pair of wires into a vise to hold it. He put the other end of those wires into a hand-cranked drill and tighten the chuck on it. Then he turned the handle to twist the two wires into a neat twisted pair.

Answer 2

Are you using braided -OR solid wire? The solid wire should hold the twist with no problem, but the braid will want to unwind no matter what you do. In fact, if you twist it to much, strand will break.

If you must use braided, consider a "wire management" approach. There are plastic spirals "Slinkies" that you wind around a bundle of wires that keep everything together. When applied, they have the appearance of a flat snake winding around the wire bundle. I get them from one of the office super stores, but places like Circuit City, Best Buy and Radio shack also probably have them. The beauty of them is that you can unwind them later if need be.

Here's a picture of the product:

Otherwise, consider heat-shrink wire wrap, which should be at Lowes or HD. After you've wrapped it around your wires, hit it with a heat gun or hair dryer and it shrinks around the wires to unify them.

I hope this helps.

Answer 3

If it feasible to do this by hand, there is a distinct advantage. If you are care full, the action of twisting by hand in such away that there is no stress on the wire while twisting (as you twist the group each wire twists oppositely in order to relieve stress on the wire) then the end product will stay together with no tying or gluing or sheathing. This will not occur with mechanized winding.

Answer 4

tie the wire to a post, allow for waste cut off, chuck the wire up in a drill ( cord or cordless ) spin the wire to your desired twist, add more twist that needed to allow for unwind factor

Answer 5

use a shielded cable or place the wires in a metal conduit for noise reduction and ground the shield on one side or make sure the conduit is grounded....
