Default Old 4 core SWR cable

Just curious- I dug up and I am re-using some old 4 core steel wire reinforced 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.

Terry.

It is used during manufacture and has no function in the finished product.
