Live Pot End Kits For XLPE & PILC Low Voltage Cables
Pot End Joints
Standard heat shrink end caps are often used to seal cable ends of low voltage cable joints. However where cables are live (energised) heat shrink live pot end kits should be used. Each cable core is separately sealed using small cable caps and a screen bandage is applied to re-instate the earth fault protection.
Finally, a thick wall outer heat shrink cable cap is applied marked with a live flash symbol.
Heat shrink pot ends are available for EPR, XLPE and PILC paper insulated multicore cables. Service cable pot-ends to DNO specification are available to suit single and three phase CNE cable (4-35sqmm) and single and three phase PILC cable (16-35sqmm).
Live pot-end cable seals are also available for single and 3 core 11kV medium/high voltage power cables:
- Pot End Live Cable End Seal | 11kV Cables Single Core XLPE CWS
- Pot End Live Cable End Seal | 11kV Cables 3 Core XLPE EPR

For XLPE & PILC Low Voltage Cables
|SPS Part Number PILC Cable||Pot End Cable Range (sqmm)||SPS Part Number XLPE Cable|
|POT 4-10-4PB||4 Core 4-10sqmm||POT 4-10-4X|
|POT 16-35-4PB||4 Core 16-35sqmm||POT 16-35-4X|
|POT 50-95-4PB||4 Core 50-95sqmm||POT 50-95-4X|
|POT 120-185-4PB||4 Core 120-185sqmm||POT 120-185-4X|
|POT 240-400-4PB||4 Core 240-400sqmm||POT 240-400-4X|
The table shows common 4 Pot End kits, for 2 or 3 core kits the codes should be changed by substituting the figure 4 shown after the cable range to either 2 or 3.
Example: For a 3 core XLPE kit 35sqmm, the correct code should be POT 4-35-3X
Abandoning LV Cables Using Heat Shrink Pot-End Kits
Traffic Master, the satellite-based tracking solutions provider for remote-based mobile assets, placed an order with Thorne & Derrick International following successful field testing and installation of samples by the team of engineers. The pot end joint kits will provide safe and effective cable abandonment for several thousand redundant 2 core low voltage XLPE SWA 16-35sqmm cables to BS5467 – this includes a mixture of armoured street lighting power and motorway communications cables. Both standard and customised heat shrink pot end joints are available to abandon redundant LV-HV cables.
