Nexans Power Cable Accessories & The Innovative JTS Joint for Medium Voltage Cable
February 8th, 2022
MV Cable Joint – JTS
Improved Reliability & Safety at Reduced Cost
Nexans Power Cable Accessories is the UK’s leading cable and accessories company that has recently announced the launch of a new innovative product range that will ensure safer, easier and time efficient installations.
With their UK base in Castleford Nexans Power Cable Accessories has launched the new JTS Heat Shrinkable MV Joints range which boasts unique design features developed to reduce installation time, minimize risk of failure and simplify installation.
Launched at ENERGYX2021 event in Chester, the new JTS Heat Shrinkable Joints Range feature a range of design innovations that will deliver cleaner, quicker and simpler jointing installations. These features include:
- Innovative triple wall technology where three inner tubes have been extruded as one, and as such, requiring only one heat shrinking activity instead of three
- The use of this triple wall tube meaning the chance of misalignment is reduced by a factor of 3 to 1 and;
- The inclusion of a revolutionary integrated faraday cage section within the connectors mastic patch minimizes misalignment in critical areas.

MV | Robust Outer Sealing & Protection & Advanced Electrical Stress Control
latest innovation to MV cable joint range
Speaking about the new product range Joe Roberts, UK & Ireland Sales Manager at Nexans Power Cable Accessories UK said: “We are delighted to be launching this product range to market and with what we consider to be some of the most innovative technology available to date”.
“As a business we pride ourselves on pioneering new ways of working and new technologies that ultimately make cable installations slicker, quicker and easier whilst consistently delivering products that meet the very highest standards of health and safety. We are immensely proud of our new JTS Heat Shrinkable Joints range and are very much looking forward to launching it, not only at ENERGYX, but over the coming months as we introduce these products to the marketplace.”
Alongside the range of unique design innovations, the new MV Cable Joint JTS Heat Shrinkable Joints Range also offers a host of additional installation benefits designed to speed up, simplify and improve safety across the install process. These include:
- A compact, slim design with sizes ranging from 95mm² to 1000mm²

MV Heat Shrink Cable Joint Development
After engaging with Europe’s major MV installation companies to find out their thoughts on how to improve standard MV heat shrink cable joints. The main features were found to be – reduce the installation time, minimise the failure risks and simplify the installation.
Reduce Installation Time
This was achieved by the innovative design featuring “triple wall” technology, where the three inner tubes for semi conductive conductor screen, insulation, and semi conductive insulation screen have been extruded into one simple triple wall tube. This requires only one heat shrinking activity instead of the usual three, and the new design of roll on mastic pad to go over the connector eliminates the requirement for additional mastic tapes as in previous designs which can tend to stick to each and become very messy. The new design results in a much quicker and cleaner installation.
Minimise The Failure Risks
By the application of the triple wall extruded tube, this has effectively reduced the problem of misaligning the over tubes by a factor of 3 to 1 and maximizes coverage of the screen cut area – this, together with a new design of roll on mastic patch over the conductor area featuring a revolutionary “Faraday Cage” built in inner semi conductive layer also minimizes potential for misalignment in these critical areas.
Simplify the installation
By the application of these new and innovative design features, together with improved jointing instructions featuring high resolution images and easy to read step by step text, the whole process of installation has been simplified and no additional jointer training will be required to install the JTS.
TRIPLE WALL HEAT SHRINK CABLE JOINTS
Single Tube with Triple Function
The below video shows the Triple Wall design of the JTS Joint reducing installation times with corresponding labour savings.
Traditionally, heat shrink joints required several separate stages for the installation of the complete cable joint with multiple layers of heat shrink tubes needed to provide stress control, insulation and conductive functions – the labour intensive jointing procedure introduced increased risks of jointer error including tube misalignment and flamework deficiencies (scorching of tubes by overheating).

Port Of Felixstowe

This month, we have been working with our client Hutchison Port Holdings and their High Voltage Engineering Team to supply a specification solution to repair and joint flexible reeling type EPR cables – the 11kV medium voltage power cables operating the quay and rail mounted gantry cranes at Port of Felixstowe required a permanent, compact, smooth profile and flexible cable sheath repair product.
Thorne & Derrick’s proposed solution using the M Series of Flexible Cable Repair Products manufactured by 3M Electrical, combines permanence with flexibility and reliability when installed by approved jointers.
The cable damage details:
- 1m of outer sheath tape delaminating where the cable was previously jointed under warranty by the manufacturer. The cable was removed and on a drum ready for repair.
- 2.72m of outer sheath damage. The cable was still working on the cranes with a temporary repair in place. The cables needed to be repaired in situ with a shelter and work area erected around the damage to allow for dry and convenient cable jointing.
This specification has been adopted as the engineering standard for future repairs to site damaged cables at Hutchison Ports operating facilities.
➡ Listen to Rachel Salisbury (Application Engineer 3M UK plc) explain the benefits;
Thorne & Derrick have been Distributors for 3M Electrical since 1985 and can provide customised repair solutions using Scotchcast resins, Cold Shrink or high performance tape repairs across all industry sectors. More Reading:

Best For The Environment – Investing In A Low Carbon Future
The Port of Felixstowe is Britain’s biggest and busiest container port, and one of the largest in Europe – dealing with 48% of Britain’s containerised trade. Thorne & Derrick are also delighted to be working with a site that is committed to reducing their carbon footprint. While the Port of Felixstowe itself actually contributes less than 1% of the total carbon embedded in goods through the supply chain, they are committed to making significant progress in reducing this, as well as the impact of the overall supply chain.

HVDC | France to Italy Link
A New Power Highway Through The Alps To Build Europe’s Energy Grid
GE Grid are currently working on a high-voltage, direct current (HVDC) electric power transmission system to support the interconnection of the European Grid. Transitioning towards better integration of renewable power and reducing carbon footprint, transmission operators RTE (France) and TERNA (Italy) have decided to build the world’s longest (HVDC) cable interconnection. This link – at 190 km – will join the French and Italian electricity networks under the Alps.

| 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.
