Medium Voltage Terminations

Medium voltage terminations make use of heat shrink technology to provide a solution for both indoor and outdoor applications.

Suitable for both single and three core cable they combine different grades of heat shrink tubing and mastics to completely restore the integrity of the cable after the cable has been terminated. The control of the electrical field being essential for the safe operation of medium voltage devices.

Features and Benefits

Heat Shrinkable Power Cable Terminations


1. Non-tracking, heat shrinkable outer insulation tubing
– Provides excellent UV stability; Withstands polluted environments; Is proven to withstand severe applications
2. Non-tracking, high voltage sealant
– Provides watertight seal over cable lugs
3. Additional heat shrinkable creepage extenders for outdoor applications
– Increase surface creepage distance; Easy to adapt indoor terminations to outdoor conditions
4. Heat shrinkable stress control tubing
– Reduces electrical stress gradient at the end of the cable shield to safe operating levels
5. Stress relief material
– Minimizes stress at the shield cutback; Acts as a moisture seal
6. Ground clamp
– Has a constant force roll spring, which provides secure grounding without soldering
7. Shielding and solderless grounding with ground braid
– Provides shield continuity
