Ampetronic DBC cables are intended to be used for direct burial in soil or concrete (usually in the screed layer). This provides a cable installation option where there is no floor covering or other installation location, even if the planned screed is too thin to accommodate conduit. The EPR-CSP HOFR insulation of the cable is resistant to attack from the strong alkalis present in concrete (unlike standard PVC-insulated wire), and prevents loop failure due to corrosion of the copper.
