WOER heat shrink cable joints provide versatile solutions for 1- to 5-core cables, accommodating both armored and non-armored configurations including 3+1, 4+1, and 3+2 cable types. Featuring adhesive-coated insulation tubes for reliable sealing and insulation, each joint includes a protective outer tube replicating cable oversheath performance with mechanical durability and chemical resistance. WOER's innovative design maintains conductor crossability while ensuring exceptional cable termination security for diverse power applications.
The joints are designed for MV screened, 1-core polymeric insulated cables with or without armour. The same design principles are used for 3-core cables.
Electrical stress control
Stress control tube, together with stress relief mastic, is used to smooth out the electrical field at the cable screen ends.
Insulation and screen
Heat shrink insulation tube delivers consistent insulation thickness to meet or exceed that of the cable.
Heat shrink semi-conductive /insulation dual layer tube is also adopted to help ensure a void-free interface between the insulation and screen.
Metallic shielding
Copper mesh wrapped around the joint area rebuilds the metallic screen. Either soldering or solderless earth connection is available to provide screen continuity across the joint.
Outer sealing and protection
The outer sealing and protection is performed by an adhesive coated heat shrink tube. It provides mechanical protection and chemical resistance as expected from cable oversheath.
