Anyway, having confirmed the conductor size at 6mm sq, why are the
over-insulation dimensions so much smaller?

Thinner insulation to cut manufacuring costs?
Thinner insulation to allow better heat disipation?
Thinner insulation because the modern materials used are superior?

Anyone got any other ideas?

I would expect that the length of cable removed was about 20 years old.

There seems to have been a re-think about the thickness of insulation
required (which would be mainly for mechanical protection) - the same has
happened to car cable.
