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.

WHAT IS AN ARC FLASH?
An electric arc occurs whenever a circuit breaker, switch or isolator (Device) is opened and when there is current flowing in the circuit. However, most devices under normal operating conditions are designed to control the arc when opening or closing.
An arc flash may occur when the arc is uncontrolled and there is sufficient energy released to cause harm or damage.
Arc flashes occur both at high voltage and low voltage. There is little discrimination: low voltage arc flashes injuries are just as damaging at high voltage injuries.
Put simply: An Arc Flash is the light and heat produced from an electrical arc supplied with sufficient energy to cause significant damage, fire or injury.
An Arc Flash can cause minor injuries, third-degree burns and potential death as well as other injuries including blindness, hearing loss, nerve damage and cardiac arrest. Fatal burns can occur when the victim is several feet from the arc. Serious burns are common at a distance of 10 feet – arc flash can generate heat 4 times greater than the surface of the sun.
