HV Cable Joints, Terminations & Connectors
➡ T&D distribute the most extensive range of HV High Voltage Cable Joints, Terminations & Connectors from manufacturers including 3M, Prysmian, Nexans Euromold, Elastimold, Pfisterer CONNEX and Shrink Polymer Systems.
Heat shrink, cold shrink, push-on and slip-over cable accessories enable the jointing, terminating and connection of 11kV-33kV and 66kV-132kV cables to oil, air or gas insulated switchgear, transformers, motors and overhead lines distributing electricity at medium/high voltages.
We hold large stocks of 11kV and 33kV joints and terminations suitable for XLPE, PILC and EPR cables to service the medium/high voltage power cable accessory requirements of UK and international customers.

Cold Shrink & Heat Shrink
Joints & Terminations
T&D supply both cold shrink and heat shrink cable terminations – conventional heat shrink terminations continue to be most extensively used to connect cables into air insulated cable boxes, switchgear and transformers providing stable performance in industrial installations located both indoors (substations) and outdoors (pole-mounted overhead line) applications.
Increasingly, cold shrink terminations and joints are preferred with less installation steps reducing scope for jointer error and the consistency of application achieved due to the elimination of the skill sensitive requirement to apply consistent and even surface heating to heat shrink terminations.
Cold Shrink Termination
Using 3M Cold Shrink type QT111 cable terminations the video demonstrates the flexibility and simplicity for terminating HV cables – the shorter installation length of the termination enables compact cable terminations into 11kV/33kV electrical equipment. No requirement for heating or tools ensures quicker and easier installation. The following video discusses the installation process for cold shrink terminations to MV HV screened cables.
Heat Shrink Termination
In this next video the procedure for installing heat shrink cable terminations is covered including key stages of the MV HV cable preparation process – a 33kV single core cable termination with polymeric (XLPE) insulation is installed.
Cable terminations and joints for use on MV HV electrical power distribution systems should only ever be installed by trained and competent Jointers in accordance with the manufacturers installation instructions – Thorne & Derrick can provide expert technical support to ensure the supply of the correct cable accessory for medium/high voltage cables supported by manufactured provided Cable Jointer Training.
