One sort of cable system I still see a wee bit of over here, is the old cloth-covered rubber wires inside wood casing, it used to be used here for Service Lines into the main switchboard here.
Thankfully most of it has been removed these days, I accidently stood on a length of it when working up in a roof once.
Man did it go off with an explosion!!, the casing was only just holding the (now bare) wires apart inside and once disturbed, look out!.
Worse still, the heat from the explosion ignited the wood splinters.
I really watched what I stood on up in roof voids after that.
That would be a surprise!.
We have a cut-to-length service here for most types/sizes of cable.
Sure, it does cost a bit more, but it saves wondering what you're going to do with what's left over, especially if it's a really odd type of cable.
