    If it looks a bit like this stuff. then as others have said,

     It is split concentric cable - common for use by DNOs, not quite as good as SWA as there is not an overall earthed armour - half of the 'not really an armour' is neutral. but easy to work with and good for EMC. Can be buried, but needs to meet the same routing rules in walls like T and E to meet BS7671.

    CSA is normally stamped on the jacket, but if not, size from the live core, N has slightly more current handling capacity, being better cooled
