MV Cable Joints

Improved Reliability & Safety at Reduced Cost

A modern generation of MV Cable Joints have been developed by Nexans for the UK utility and contracting industry – the primary application is for the jointing of 11kV 24kV and medium voltage power cables up to 33kV/42kV.

The JTS cable jointing system now provides the most cost-competitive option to power contractors: the MV cable joints manufactured by Nexans, “The Global Expert in Cables & Cable Systems” are tested in accordance to CENELEC HD629.1.

The internationally recognised quality standard ensures power system reliability and outage reductions when installed in accordance with the manufacturers instructions by Competent cable jointers.

➡  MV Cable Joints 11kV Range | The cable joints include high quality heat shrink tubes and components – the JTS range suits polymeric cables (XLPE & EPR), single core (up to 1600sqmm) with copper wire screens and voltage 11kV (Umax 24kV).

Triple Wall Heat Shrink Cable Joints

Single Tube with Triple Function

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).

The Triple Wall design of the JTS Joint reduces installation times with corresponding labour savings.

The triple extruded heat shrink tube with integrated stress control provides compact installation with reduced components and excellent water sealing for direct burial into underground cable trench.


Mechanical connectors are included for fast jointing of conductors without resort to hydraulic crimping tools and associated die sets.

Stocked and distributed in the UK, the MV cable joints are now available from Thorne & Derrick with complete technical support, fast quote service and next-day delivery.

The cable joint kits include clear step-by-step Jointing Instructions – Competency Certification can be issued, contact us.

Triplex Cable Joints & Terminations

Nexans manufactured Cable Accessories are in extensive service throughout the UK DNO power grid – the Euromold brand of separable connectors are approved and are approved by several DNO/IDNO operators dependent on the product, voltage and network.

Nexans joints and terminations are increasingly preferred and adopted by NERS Accredited Independent Connection Providers (ICPs) working on 11kV private networks.

Thorne & Derrick have an International Distribution Agreement with Nexans Power Accessories UK and are their main stockists and suppliers for their range of Heat Shrink Joints & Terminations up to 33kV.

Cable Terminations

Nexans MONOi heat shrink cable terminations are a one-piece co-extruded anti-track (red) and stress control tube for connection and terminating 11kV BS7870-4-10 Triplex Cables 95-300sqmm into medium voltage electrical equipment.
