Thorne & Derrick Secure New Renewable MV Cable Accessory Order
This month, Thorne & Derrick International were delighted to confirm receipt of a new purchase contract order for an offshore wind farm project – this is to supply 33kV Tee Connectors (Nexans Euromold) and Inline Cable Joints (3M ColdShrink) following several rounds of technical qualification, specification and commercial submissions.
Thorne & Derrick’s technical submission for the jointing of the 33kV cables was accepted by the Senior Lead Cable Specialist based upon their 3M QS2000 range – the cable joint designed utilises a unique Cold Shrink delivery system. The 3M Cold Shrink products are supplied pre-stretched on a removable core for efficiency and ease of installation by the jointer with an integral electrical field control device and faraday cage pre-installed in the insulation body to reduce complexity during the installation.
As Approved Vendors to Vattenfall, the Swedish multinational power company, Thorne & Derrick will be supplying a 33kV Inter-Array Cable Accessory Package including medium voltage joints, connectors and cable cleats to support the installation of 19/33 (36)kV Single Core Submarine Cable with 24 Fibres (IEC 60502-2).

52kV Trackside Power
Pictured Termination: 3M 95EP-631-2 is a 52kV Single Core Outdoor Termination utilising QTIII Technology for 26/45(52) kV Cables. Here’s a pallet shot of a Network Rail project order we have shipped out from Thorne & Derrick in April. The 52kV Cable Terminations manufactured by 3M Electrical utilising their innovative Cold Shrink Technology are Network Rail (NR) certified and PADS Listed as meeting the requirements for installation on their electrical infrastructure.
 Thorne & Derrick supply an extensive range of 400V-33kV Rail Cable Accessories & Power Distribution Sytems including feeder pillars to contractors undertaking Low Voltage Power Distribution, HV Electrification & Substations, DC Traction & Networks, OLE and Track Feeder Cable Renewals.
From stock, we deliver HV Terminations to trackside or turbine – whatever the industry, wherever the cable.

Preserving The Heritage
A heritage studio revived for the 21st Century
We are currently working on an exciting project with a heritage film studio, that is undergoing work to expand. The studio plans to expand the complex with new studios and workshops to bring it into modern times and continue use.
Thorne & Derrick are working with the client to provide cable protection and ducting solutions to assist with the expansion project.
Cable protection covers and underground warning tapes are installed over LV, MV and HV power cables in trench and ducted cable installations with high visibility colour providing a visual warning of danger when excavating cables.
Read more about Cable Protection
Thorne & Derrick also stock and distribute a range of cable ducting solutions that are independently certified to British and European Standards and are used extensively for LV, MV & HV substation, highways, housing developments, commercial, retail and industrial infrastructure applications. ➡ View the complete range of Cable Ducts to provide underground cable protection of low, medium and high voltage power cables (LV MV HV) including 11kV and 33kV cable ducting.
Technical Tips
Thorne & Derrick are the Specialist Distributor & Stockist for Alroc in the UK for their ranges of manual and motorised Cable Preparation & Jointing Tools for the removal and stripping of outer cable sheath, semi-conductor screen and insulation from LV, MV, HV and EHV power cables.
The ORACL manufactured by Alroc and supplied by Thorne & Derrick enables the cable jointer or user to longitudinally score the peelable semiconductive layer from medium/high voltage cables (typically 33kV up to 1000sqmm) in order to peel it off carefully by hand – this is a key stage of MV HV cable preparation prior to the installation of Power Cable Accessories including joints, terminations and connectors.
The ORACL screen scoring tool covers most “easy-strip” peelable semicon thicknesses by having adjustable scoring depths of 0.4, 0.6, 0.9 & 1.1mm – contact us for prices, stock availability or further information.
