This document describes low voltage cable jointing kits that provide safer, faster, and more reliable joining of cables. The kits use a unique resin delivery system that totally encloses the mixing and pouring, preventing spillage and accidental contact. The polyurethane resin is as strong as the cables and cures quickly. The kits include molds, resin, armour continuity components, tapes, and instructions. They are suitable for joining PVC, SWA, PVC, and XLPE insulated cables up to 3.3kV or 6.6kV for unscreened cables. Supplementary kits allow transition and paper cable joints.
