I've always known it as VIR.
I replaced miles of it in the late 60's with PVC singles.

If you google VIR / VRI it comes up about 50 /50.
With a few people insisting it's VRI.

I suspect VRI was the original (sounds a better description) and probably Trademarked or Copyrighted by the first manufacturer.
Then all following manufacturers had to use VIR as the description.

However VIR / VRI refers to singles.
TRS is probably the correct title for VRI /VRI singles within a Rubber sheath.

I done abit of Google myself last night and found it to be 50/50. I've only known it as VIR because when I was jointing that's what UKPN called it in their documents.

Well two people recall cab tyre. These things are a bit connected as the black tough rubber sheath on cables was like Indian cab tyre, vulcanised Indian rubber or VIR. VRI is the correct term.

My old mentor actually called it cab tyre and he explained the Indian cab tyre bit, might be bull but he was right on most things or at least he told me he was.

It is referred to as cab tyre in some of the old electrical books I have. Daz

It all seems similar with different names. TRS or tough rubber sheath is also called CTS or cab tyre sheath.

 

[Sparks1962]

Its all the same stuff. The man I was apprentice to back in the '70's who had been in the trade all his working life told me it was CTS (Cab Tyre Sheath), Cab Tyre for short.
He also told me VIR stood for Vulcanised India Rubber, but I guess you could call it Vulcanised Rubber ( India )

In my collection of pre -war textbooks it's referred to as CTS and / or VIR .
