TE Connectivity’s (TE) Raychem elastomeric joints are suitable for all polymeric cables and can accommodate various cross-bonding shield break and external grounding arrangements. The joint design employs a connector that allows even large cross-sections to be jointed and two dual-wall, heat-shrinkable
sleeves. A heavy-walled co-extrusion of two layers of red insulation forms the inner sleeve. The outer sleeve consists of a thick layer of red insulation co-extruded under a black outer conductive layer which acts as the insulation shield (semi-con
The set of pre-engineered components and the Raychem connector require no special installation tools. After placing the
heat-shrinkable components over the cable end, the connector is installed by tightening the special bolts, which shear off cleanly when the correct contact force is reached. Each sleeve in turn is placed over the connector area and shrunk down. Copper shielding mesh and an adhesive-coated outer sleeve for water sealing then complete the joint.
