The document discusses JEM resin and JBRCC low voltage universal cable joint kits for joining copper and aluminum conductors from 1.5mm2 to 300mm2. The kits include JEM resin, which has advantages like being isocyanate-free, having low viscosity for void-free filling, and being insensitive to moisture. The kits also include mechanical connectors that require no special tools and allow for a good conductor range, as well as armour bonds. The document provides specifications on the kits, including part numbers for different conductor sizes and core configurations. It also gives dimensions for the joint shells.
