Nexans Power Cable Accessories For Wind Energy Projects
by Chris Dodds T&D - estimated reading time 5 minutes
T&D are UK Distributors for Nexans Power Accessories – this includes WINDLINK a range of medium and high voltage accessories including cable joints, terminations and connectors suitable for wind turbines on offshore and onshore wind energy projects.
Nexans Power Accessories provide a complete range of accessories suitable for energy distribution networks such as pre-moulded EPDM rubber connectors and silicone terminations for cables, epoxy bushings for transformers and switchgear, a wide range of cold and heat shrinkable terminations and joints up to 66kV as well as customised, rated jumper cables for medium voltage applications.
With the Nexans & Euromold product portfolio of Cable Accessories is a whole range of products for low voltage networks: terminations, straight and branch joints, gel or resin filled, heat or cold shrink joints.
Nexans manufactures ferrules and cable lugs to connect low, medium and high voltage power lines and cables. A wide range of cable crimping joints and lugs, mechanical connectors and cable lugs with shear-off-head bolts for connecting different conductor cross-sections of aluminium and copper cables is available.
Terminations are used to connect polymeric insulated cables to MV-HV electrical equipment and for the outdoor terminating onto overhead lines or busbars. Indoor terminations are designed for use in controlled environmental conditions and subject to light condensation.
Outdoor cable terminations are designed for prolonged exposure to sunshine and other weather conditions.
Straight joints are designed for jointing screened polymeric cables to be laid in air or directly buried – these cable joints are fully screened and fully submersible.
For offshore wind power parks, the Offshore Junction Cabinets and the Offshore Junction Frames are used as a connecting point for internal tower cables to external subsea power and array cables. Nexans OJC and OJF product lines are part of our dedicated WINDLINK offer.
Separable connectors are designed to connect polymeric insulated cables to equipment such as 11kV/33kV transformers or switchgear. These cable connection products are suitable for indoor and outdoor use with thick conductive EPDM jacket to provide a total “safe to touch” screen which ensures safety for personnel.
Cable jumpers are prefabricated lengths of cable on which a separable connector or a cable termination is installed at each end.
Surge arresters are designed to protect medium voltage components, including transformers, equipment, cable and accessories from high voltage surges caused by lightning and switching up to 66kV.
Equipment bushings are epoxy insulated parts for use in oil or gas insulated equipment, such as transformers, switchgear and capacitors up to 66kV.
Slip-on cable accessories for 66kV/72.5kV wind applications: separable connectors to connect cable to switchgear or transformers, slip-on terminations to connect cable to equipment and for outdoor termination of cables onto overhead lines or busbars, slip-on joints with mechanical connectors for jointing cables inside the wind park.

Special thanks to Robert Coleman for his step by step explanation about the processes involved in this type of 11kV joint installation – with over 30 years cable jointing experience at 11/33kV Robert is qualified to explain the skills and techniques required to effectively work on medium/high voltage power cables in challenging workplace locations.
It was the morning after the day from Hell with 60mph gusting winds and rain lashing sideways from bleak skies – not the conditions for comfortable 11kV jointing. The bottom of the cable joint hole was 6 inches deep in slop so first job to do was to dig a small sump hole and bail out the excess water. Wooden blocks were used to elevate the cleaned down 11kV cables and keep them out of the mud bath.
The 11kV cable is the relatively new UKPN standard – aluminium wire screen 11kV Triplex with 300sqmm conductors and jointed using UKPN Issue Tyco SMOE 64541 heat shrink cable joints in an underground cable trench.
Alroc – Cable Tools (LV MV HV EHV Cable Jointers Tools)
Using the correct cable jointing tools is critical – failure to achieve semicon screen cut perfection and excellent insulation removal will compromise life cycle of the cable accessory and ultimately cable circuit.
Alroc PG3 cable strippers were used for ringing off and stripping the outer MDPE cable sheath to the dimensions shown in the jointing instructions.
The Alroc semi con stripper is used on the fully bonded semicon screen layer to 40mm from the aluminium wire screen cut.
The Alroc insulation stripper is set at 60mm and used to remove cable core insulation to desired length of the mechanical shearbolt connector. A thorough clean of the XLPE insulation with PF impregnated cable cleaning wipes working from the insulation cut towards the semicon ensures all traces of the semicon have been removed.
A light blow over with a slack flame from a gas torch is required to dry residue from the cable wipe – then apply the yellow void filler at the screen cut to dimensions in the instructions. A stress control tube is then applied in line with the insulation cut and heat shrinked using a slack flame working toward the aluminium wire screen.
Aluminium screen wires are bent back and stripped so the semicon layer is exposed.
A build up of black tape is used and then the brass ring slid onto the cable and over the black tape for a snug fit – the wires are brought down onto ring and temporarily secured with black and red heat shrink tubes.
Once the heat shrink tubes are applied then the 11kV shearbolt connectors can be “snapped off” in sequence – use putty to fill voids in the cable connection then black void filling mastic is applied over the bolts and around the connector. Next slide black and red heat shrink tubes over the shearbolt connectors and heat shrink using a slack flame working from the centre and around the 11kV cable.
Once fully shrunk allow the 11kV joint to cool before the copper braid tape is applied half lap, side to side, of the cable joint and the copper braid secured down on both sides of the aluminium wire screen with Jubilee clips. Repeat this process on the other 11kV cores before finally wrapping the last copper braid tape around the whole cable joint, half lap and securing at the end with a half hitch.

Sonus XT – Compact Ultrasonic Testing Device for Preventive Maintenance ON MV HV Switchgear & Cables
uploaded by Chris Dodds - reading time 2 minutes
The versatility of the Sonus XT makes it ideally suited to work with any plant maintenance program and the perfect complement to other Predictive Maintenance (PDM) Technology.
The ultrasonic testing device is easy to use converting ultrasound into audible signals showing instantaneous and maximum sound level readings in decibels.
Ultrasound detection can be utilised to transmit early warning signs that detect faults on connections in cabinets and OHL (when using the parabolic dish – available as an optional extra). Inspections can be performed quickly and safely by plant personnel with minimal training. Fast and accurate diagnosis of problems using the Sonus XT will save you time and money.
The Sonus XT can quickly and safely perform closed panel airborne ultrasound inspections of electrical equipment including Switchgear, Switchboards, Panelboards, Transformers, Motor Control Centers and Process Equipment Panels to detect early warning signs including: Arcing, Tracking and Corona.
➡ Please note Sonus XT detects PD at above 5kV as it definitely won’t work on LV systems.
