Cable Jointing

Despite challenging and awkward working conditions including confined spaces, contamination and muddy cable trenches the Jointer demonstrates exemplary personal skills to ensure cable preparation standards are to the highest industry levels.

The workmanship was attained using a combination of precision engineered specialist cable jointing tools – the tools used included Boddingtons manufactured semicon stripping tools and Alroc brand tools to strip the primary insulation (XLPE) and outer sheath jackets from the high voltage cables.

Routinely, the Competent Jointer takes care and pride in workmanship and thoroughly polishes the XLPE insulation prior to the installation of joints, terminations or connectors.

“An excellent example of radial semicon layer cutbacks in a challenging environment. Provided the rest of the cable joint components are installed properly these cables would likely pass a factory comparable partial discharge test in the field and provide long reliable service,” commented Ben Lanz.

Ben Lanz is Director of Applications Engineering at IMCORP USA and has expert technical oversight of power cable life cycle consulting (5kV-500kV). Ben has published several technical papers on power system reliability, asset management, diagnostics and regularly presents on the topics. He is a Senior Member of the IEEE Power & Energy Society, a voting member of the IEEE Standards Society, and a member of the IEEE Dielectrics and Industrial Applications Societies. He has served as Chairman of the Insulated Conductors Committee (ICC) technical committees responsible for cable testing, cable reliability and surge arresters.
