METHOD FOR MEASURING THE WALL THICKNESS OF A PLASTIC SHEATHING FOR AN ELECTRICAL CORE OR CABLE, IN PARTICULAR A POWER CABLE

摘要

A method for measuring the wall thickness of a plastic sheathing of an electrical core or cable, in particular a power cable having at least one core, wherein the absorption capacity of the material surrounding the plastic sheathing approximates or is similar to that of the plastic sheathing, wherein the core or the cable is irradiated at a right angle to its extension on one side by x-ray radiation and the wall thickness of the encased core or cable is determined on the opposite side from the distribution of the intensity of the detected x-ray, characterized in that the material of the plastic sheathing or a plastic material surrounding the plastic sheathing is foamed prior to measuring the wall thickness for the purpose of modifying its absorption capacity.
