MV HV Cold Shrink Joints
Stocked & Supplied by Thorne & Derrick | Technical Support | Competitive Prices | UK & International Projects
Thorne & Derrick distribute 3M Cold Shrink Cable Joints suitable for jointing, connecting and splicing medium and high voltage (MV-HV) cables including 11kV, 33kV, 66kV and 132kV – we provide competitive prices for cold shrink cable joints from extensive stocks to UK and international destinations.
3M Cold Shrink Cable Joints include built in components to ensure sound insulation, stress control and adequate earth potential over the screens of medium voltage cables. The 3M Cold Shrink Technology ensures constant radial pressure is exerted over the cable for the duration of the cable joint’s life.
The Simple Application Of A 3M Cold Shrink Cable Joint
 |
 |
 |
 |
| 1. Place the 3M Cold Shrink splice body onto the prepared cable, connect the cores and clean cables thoroughly. | 2. Thoroughly grease the connected cable in preparation for the cable splice body. | 3. Once in position, begin to remove the inner coil from the cable joint body. | 4. For extra peace of mind, take advantage of the fact that cable splice body position is easily checked. |

| 5. Place the earth stocking over the splice body. Ground and secure with 3M Constant Force Springs. | 6. Insulate the constant force springs with Scotch 23 Rubber Splicing Tape and then overlay with Scotch Rubber Mastic Tape 2228. | 7. Position the pre-parked 3M Cold Shrink Outer Protection Tube over the stocking and beginning to remove the inner supporting core. | 8. Continue to remove the inner core until the outer tube is fully shrink, completing the cable joint. |
3M Cold Shrink cable joints are available in a Standard cost-effective range or Premium options for medium/high voltage (MV HV) power systems.
The Standard range covers many of the most common cable configurations and size ranges unique to the UK market but requires the electrode to be built up by the cable jointer using Scotch 13 electrical semi-conductive tape.
3M Standard Cold Shrink Cable Joints
The Standard 3M Cold Shrink Cable Joints are available for both single core and 3 core cable connections for medium/high voltage cables including 11kV 33kV 66kV and 132kV.
3M premium Cold Shrink Cable Joints
The Premium 3M Cold Shrink Cable Joints are available for both single and 3 core cable connection for medium/high voltage cables including 11kV 33kV 66kV and 132kV.
3M Super Premium Cold Shrink Cable Joints
The Super Premium 3M Cold Shrink Cable Joints are available for both single and 3 core cable connections or medium/high voltage cables including 11kV 33kV 66kV and 132kV.
Cold Shrink Joints Features
- Prefabricated one-piece Cold Shrink splice body with integrated semi‑conductive electrode forms a faraday cage over the connector and eliminates the use of tapes or additional moulded or metallic electrodes
- Fast and easy installation at temperatures ranging from -20°C to +50°C
- Suitable for a broad range of cable type and sizes
- Permanent radial contact pressure
- Simple assembly by pulling out the spiral core
- Meets exceeds the requirements of European Standard CENELEC HD 629.1 and IEC 60502-4
