Medium Voltage Joint Kits

Heat shrinkable power cable joints

Heat shrinkable power cable joints consist of high voltage insulation tubing, stress control to smooth the electrical field over the connector and screen ends, a conductive heat shrink sleeve to ensure a flawless bond between insulation and screen, copper mesh to ensure continuity of the shield, and an outer sealing jacket consisting of a heavy wall heat shrinkable sleeve, internally coated with adhesive resulting in a moisture and corrosion proof barrier on the cable oversheath.

Features and Benefits

Utility

Sealant – Internal moisture seal inhabits migration of moisture
Heat shrinkable adhesive lined tube – Adhesive lining provides moisture seal between the cable and splice; Provides impact- and abrasion-resistance
Insulation layer – Delivers consistent insulation thickness without field measurement, in a factory-engineered system; Insulation thickness should meet or exceed that of the cable
Heat shrinkable stress control tubing – Reduces electrical stress to safe opearting levels
Stress relief material – Minimizes stress around the connector and the shield cutback
Grounding and shielding – Ground braid provides continuity across the splice; Ground clamp provide secure grounding without soldering; Shielding mesh surrounds the splice for personnel protection
Semi-conductive layer – Reconstructs the cable insulation shield
