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

  • Rebuild each layer of the cable at the connector and screen cutback
  • Electrical stress control
  • Insulation layer
  • Semi-conductive layer
  • Shielding and grounding
  • Environmental sealing
  • Mechanical protection


  • HD 629.1 S2
  • IEC 60502-4
  • IEC 60055-1

Typical Applications

  • Single core or 3-core medium voltage heat shrinkable joints for XLPE, PE, PVC, PILC power cable rated up to 24kV

Product Properties

  1. Sealant - Internal moisture seal inhabits migration of moisture
  2. Heat shrinkable adhesive lined tube - Adhesive lining provides moisture seal between the cable and splice; Provides impact- and abrasion-resistance
  3. Insulation layer - Delivers consistent insulation thickness without field measurement, in a factory-engineered system; Insulation thickness should meet or exceed that of the cable
  4. Heat shrinkable stress control tubing - Reduces electrical stress to safe opearting levels
  5. Stress relief material - Minimizes stress around the connector and the shield cutback
  6. 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
  7. Semi-conductive layer - Reconstructs the cable insulation shield
