Just curious- I dug up and I am re-using some old 4 core steel wire reinfor ced cable. The core colours are red, black, blue and yellow, IIRC. What I'm puzzled by is a small diameter white tube that runs within the SWR, which appears to contain a fibrous, non metallic material.
What might the fibres in the white tube be and for what purpose? They don't quite look like fibre optic material, but that's all I can think of.
Cheers.

It is used during manufacture and has no function in the finished product.
Is it running down the centre? If so, it's probably just packing, filling space.

It is just packing to fill what would be a void in the finished shape. Just cut it off when making the ends up.
Originally they are a kind of strengthening from thestuff being bent too much is what I was told. One used to find it also in some long audio cables. It was often spiralled around or ran straight through the middle as I recall.

If it is XLP, don't attempt to bend the cores when the temp is below 5 centigrade, which it seems to be in Scotland at the moment.
