This document provides information on MPJEM low voltage industrial cable joint kits that are used for straight joints on copper conductor cables from 1.5mm2 to 400mm2. The kits feature a low hazard resin that is easy to mix and extremely low viscosity for void-free filling. They include transparent injection molded shells up to size 4 and vacuum formed clear shells for larger sizes. The kits are for joining low voltage polymeric insulated copper conductor cables to BS5467, BS6346 and IEC 502 standards.
