Sanding MV HV Power Cables
Alroc AMF5 55-160 tool can be used on HV-EHV transmission and distribution cables with an outside diameter range of 55-160mm and is designed to make the removal of cable insulation simple and efficient with significantly reduced sanding required by the cable jointer using a lower grit abrasive.
Sanding Cables Using Abrasives
Research has proven 120 grit to be optimum: fine enough for the medium/high voltage interface and yet coarse enough to remove semi-con residue without “loading up” the abrasive cloth. The abrasive must have a non-conducting grt. Do not use emery cloth or any other abrasive that contains conductive particles since these could embed themselves into the cable insulation. When using an insulation diameter dependent product eg moulded rubber cable accessories, care must be taken by the cable jointer to abrade the insulation of the medium/high voltage power cable below the minimum specification for the product.
