I've just come across a 50-ish-year old ring circuit where one cable at the CU is the usual 7/0.029" red/unsheathed/black Imperial T&E cable, but the other cable is red/transparent/blue, all three conductors (apparently) 7/0.029". I've never seen this cable type before - is anyone familiar with it, and if so, what's its story?
Produces a less lethal smoke than PVC, but does burn rather too well for comfort, is less lossy to RF, and apparently does not char in the way required to operate an AFDD...
If you have an offcut of insulation, PVC will sink in water PE will float.
