General information

The apparatus (Cablecheck) has been designed and manufactured by Bilfinger.


Cablecheck is used in quality control inspections and troubleshooting in production of power cables.


The external semiconductor for a cable sample is removed and thereafter immersed in paraffin oil at approximately 130 C. At this temperature, the crystalline components melt and the sample becomes amorphous and transparent.

With a light source and a microscope, contaminants and cavities in the insulation, as well as pips and other defects on the inner semiconductor, can be observed.

Under certain conditions, even larger water treeing can be seen in the cable.
