Hello.

Im in the process of making a cupboard for my consumer unit etc, and was wondering what the mains cable was wrapped in, and why. It looks like some sort of fabric.

Likely to be a paper insulated lead sheath cable. The outer jacket is a type of cloth which I think is soaked in bitumin.

Used by the electrical supply authorities until the mid 1960's when pvc insulation took over.

The actual cable inside is quite small once you have removed the various layers of protection!

Don't drive a screw through it when you're building your cupboard :) - there, you didn't expect good decent tips like that eh!?

The outer surface you can see is a layer called the 'serving' often made of impregnated jute, which protects a steel tape armour against corrosion, which protects the lead sheath against penetration, which protects the paper insulation against moisture. That's why it lasts so long.
