Thorne & Derrick International, a leading UK based Specialist Distributor of LV HV Jointing, Earthing, Substation & Electrical Eqpt are delighted to confirm receipt today 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 Fibers (IEC 60502-2).
The cable insulation system features water tree retardant (WTR) XLPE material, consisting of an inner semi-conductive screen, insulation and outer semi-conductive screen extruded in same operation (triplex extruded) – 3M Cold Shrink provides secure sealing and insulating of medium voltage cable termination and connections up to 36kV.
The MV cable originally manufactured by Prysmian Draka was installed by VMBMS under contract to Vattenfall Vindkraft A/S at the Horns Rev 3 project in Denmark.
Thorne & Derrick can support the specification and supply of standard and customised Cable Termination & Jointing Systems up to 66kV including separable connectors for Interface C-F Outer Cone and Size 3 Inner Cone gas insulated switchgear – extensive ranges of Cold Shrink and heat shrink jointing technologies are available from stock for immediate delivery to reduce downtime periods on unplanned cable outages.

Horstmann TP-1 | 33kV Voltage & Capacitor Tester for Euromold & NkT Connectors
March 14th, 2022
33kV Voltage & Capacitor Tester – Horstmann TP-1
Horstmann TP-1
33kV Voltage & Capacitor Tester for Euromold & NkT Connectors
Horstmann TP-I is a two-pole voltage detector according to VDE 0682 Section 415 for determination of the operating status of high voltage systems – the voltage detector is exclusively for use at capacitive LRP-test points of separable connectors:
- Euromold-angular connector with a series capacitance from 1,5pF to 3,0pF as well as
- NKT-angular connector of the types CB 12, CB 24, CB 36, CC12, CC 24 and CC 36 (all with approx. 3pF)
The Horstmann TP-I must not be applied directly at high voltage.
For testing voltage the clamp of the helix cable has to be connected with earth potential . Second the contact electrode has to be connected to the capacitive test point of the plug type cable connection.
During testing grasp only the handle of TP-I. Reaching over from the handle onto the insulated part is not allowed. Three red blinking LEDs indicate “voltage present”. This indication appears in three-phase systems in the range of 45% and 120% of rated voltage, but not below of 10% of rated voltage.
TP-I has no battery supply. During precipitation it is not allowed to use the voltage detector. Ensure that voltage detector is kept clean and dry, otherwise voltage detectors are maintenance free. TP-I must be subjected to a maintenance test according national regulations, in Germany every 6 years at the last.

March 14th, 2022
Nexans Power Accessories
UKEx Certification
Following changes to the acceptance of ATEX/IECEx certification in the UK, Nexans are please to announce that the ATEX-IECEx certified Nexans accessories now also have the UKEx marking on the label.
This UKEx certificate, granted to Nexans products for the UK market, is added to the ATEX-IECEx installation instructions of the range of the certified EUROMOLD Separable Connectors Interface A to F.
Nexans Power Accessories contracts the CML Notified body which checks 3 levels of explosion protection on ATEX-IECEx certified products:
- Preventing the formation of an explosive atmosphere
- Avoidance of the ignition of an explosive atmosphere
- Mitigation of the effect of an explosion to an acceptable extent
The applicable level for Nexans Power Accessories is #2 above.
As with IECEx certificates internationally and ATEX certificates in Europe, CML provides the UK Conformity Assessed (UKCA) marking, which is a certification indicating the conformity with the applicable requirements for products sold within the United Kingdom, which became part of UK law on exit day of the EU, January 31st, 2020.
Nexans is the only supplier world-wide to offer UKEx/ATEX/IECEx certified separable connectors, which are tested to provide a very high degree of safety in use, especially for potentially explosive atmospheres.
Our “ATEX” accessories are frequently found installed safely in industries with high technical requirements like the chemical industry, Oil & Gas, offshore platforms, and are installed in equipment such as pumps and three-phase motors.
