3M Cold Shrink Cable Terminations (MV-HV 11kV 33kV 66kV)
Thorne & Derrick distribute 3M Cold Shrink Cable Terminations for medium and high voltage 11kV 33kV 66kV cables and electrical systems – we provide competitive prices for cold shrink cable terminations from extensive stocks to UK and international destinations.
Also: 3M Cold Shrink Cable Joints for MV-HV cable jointing.
Using cold shrink cable terminations reduces the risk of cable jointer error or causing damage to the insulation of the MV-HV cable.
3M Cold Shrink terminations are available in a Standard QTII range (3M Quick Term II – Partially Integrated) and a Premium QTIII range (3M Quick Term III – Fully Integrated).

The 3M QTIII Premium range of Cold Shrink offers the greatest simplicity and flexibility, covering a broad range of MV-HV cable sizes and types and accommodating voltages from 11kV up to 66kV/69kV.
As they are fully integrated this reduces the time required to install, reducing scope for cable jointer error and the shorter installation length enables cable termination into a wide range of cable end boxes and switchgear.
Alternatively, the Standard 3M QTII Cold Shrink termination range is partially integrated, providing all the benefits of using cold shrink technology over heat shrink terminations whilst being a viable cost-based option to the fully integrated premium range. The 3M QTII range covers many of the most common cable configurations and conductor sizes unique to the UK medium and high voltage power cable market.

Using 3M Cold Shrink To Terminate Cables
|1. Prepare and strip the MV-HV power cable as normal using correct jointing tools and clean with 3M Cable Wipes||2. Place the 3M Cold Shrink termination body over the single or 3 core cable end and position at the correct point on the MV-HV cable||3. Begin to remove the inner core, allowing the 3M termination to cold shrink down onto the cable||4. Once the inner core has been fully removed, the cold shrink cable termination installation is complete|
