Power Cable Terminations for MV HV Electrical Systems Utilising 3M Cold Shrink
Stocked & Supplied by Thorne & Derrick | Technical Support | Competitive Prices
UK & International Projects
Thorne & Derrick distribute 3M Cold Shrink Cable Terminations for medium and high voltage (11kV 33kV 66kV) cables and electrical power systems – we provide competitive prices for cold shrink cable terminations from extensive stocks to UK and international destinations.
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).
QTII & QTIII type cable terminations are suitable for terminating and connecting MV HV cables. Below highlights the features of using cold shrink technology for both types of cable terminations as well as exploring the differences.
Premium Cable Terminations | 3M Quick Term III – Fully Integrated
3M QTIII Premium cable termination offers the greatest simplicity and flexibility in the full range as it covers a wide range of cable types and sizes. One of the main features that differentiates the QTIII from the rest is a shorter adjustable tail to enable it to fit into the wide range of boxes meaning fewer installation steps so there is less room for jointer error.

Standard Cable Terminations | 3M Quick Term II – Partially Integrated
3M QTII requires additional installation steps to the Premium range explained in the video below. However the Standard QTII range still offers additional benefits over heat shrink cable terminations which have many more parts to install and require heat and further tools.

The following tables and videos demonstrate the specification differences and features of both the 3M QTII and 3M QTIII versions of Cold Shrink cable termination.

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:
MV | Robust Outer Sealing & Protection & Advanced Electrical Stress Control
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:
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.
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.
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.
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.
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).
Nexans is a global player in energy transition. The Group designs solutions and services in these main business areas: Building and Territories, High Voltage Projects, Rail and Mass Transit, Renewables, Data Centres and Industry Solutions.
