Steel braided PVC cables found in an Airey house.

Possibly never intended for domestic use and may have been used in
pits and quarries is one suggestion I have had. The cables cores are
stranded copper and the imperial equivalent of 1mm.

Anyone seen it before?


Is that a wire braid outside? The insulation looks a bit like rubber
rather than PVC, which suggests it might be pre-WW2?

"In the 1930s the first trials with PVC insulations were being made in
Germany and by the end of the second world war there were significant
varieties of synthetic rubbers and polyethylene.

By the 1950s PVC was commercially viable and replaced rubber cables in
many areas particularly in domestic wiring, aluminium was also starting
to be used widely as an alternative conductor"

Steel braiding over single PVC insulated cores.



Is it steel or tin plated copper?


Pretty sure it is steel braiding. Just like a SY cable without the clear
plastic outer.
