Abstract

A method for determining conductivity of cable insulation of a cable including at least one conductor that determines the central axis of the cable and insulation layer surrounding the conductor longitudinally and radially includes steps of retrieving a cable sample from a cable, which sample includes a length of at least one insulation layer and preparing an insulation sample from the cable sample. The insulation sample is prepared from cable sample by cutting a circular layer having a set thickness at desired radius from the central axis of the cable.
