TE Connectivity Raychem EPKJ-0123 Heat Shrinkable Cable Joint Kit
The Raychem EPKJ-0123 by TE Connectivity is a professional grade, heat shrinkable straight inline splicing kit. This system is specifically engineered to insulate, seal, and mechanically protect power connections on 4 core polymer insulated cables with conductor sizes spanning from 4 mm2 to 16 mm2.
It is optimized for cross linked polyethylene (XLPE) or PVC insulated low voltage networks that incorporate mechanical steel wire armor (SWA) or tape armoring. The kit completely rebuilds the structural layers of the cable, delivering an absolute watertight environmental barrier suitable for underground direct burial, outdoor exposed trays, or underwater installations.
Key Features
-
Layer by Layer Insulation Restoration: Supplied with individual, high dielectric heat shrinkable core tubes that slide over each line connector. Once shrunk, they rebuild the primary phase insulation layer directly over the crimp or mechanical blocks.
-
Integrated Hot Melt Adhesive System: The inner walls of the protective components are pre coated with a high performance thermoplastic adhesive sealant. When heat is applied, this adhesive flows into core valleys and outer jacket boundaries, curing into an absolute moisture proof seal that blocks water tracking.
-
Heavy Duty Armor Grounding Continuity: Features a robust copper or galvanized steel grounding framework coupled with continuous force metal spring bands. This provides a low resistance earth continuity path across the severed armored wire layers, preserving full ground fault protection.
-
Thick Walled Outer Protective Casing: Includes a resilient, heavywall cross linked polyolefin outer sleeve. This outer sheath is highly resistant to impact forces, sharp punctures, structural tearing, and heavy drag abrasion on the job site.
-
Subterranean Chemical Immunity: Engineered to resist continuous exposure to soil alkalis, common industrial solvents, fungal attacks, and moisture rot, maximizing the operational lifespan of buried mainline utility runs.
