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.

Low Voltage

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.

Connection technology

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.

Cable Terminations

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.

Cable Joints

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.

Junction solutions

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

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

Cable jumpers are prefabricated lengths of cable on which a separable connector or a cable termination is installed at each end.

Surge arresters

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 bushing

Equipment bushings are epoxy insulated parts for use in oil or gas insulated equipment, such as transformers, switchgear and capacitors up to 66kV.

High Voltage Cable Accessories up to 66/72.5kV

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.

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.

Sonus XT – Features & Benefits

• Compact and robust construction aluminum body handheld unit
• Intuitive controls using five soft key pushbuttons
• Easy to use unit converts ultrasound into audible signals and shows instantaneous and maximum sound level readings in decibels
• Versatile quick-change Probe Accessories available for airborne and contact based applications
• High quality behind-the-head style headset compatible for use with hardhats
• Minimal training is required to get a Predictive Maintenance program using Ultrasound up and running
• Detect early warning signs of problems in medium/high voltage electrical and mechanical assets long before they become failures
• Find leaks and save on energy costs – finding and fixing compressed air leaks can often reduce energy costs by up to 30%
• Collect baseline and trend information on mechanical asset performance to streamline maintenance planning

Joints & Terminations For Cables

In Hazardous Area Locations

Thorne & Derrick distribute MV-HV Joints & Terminations specified for use with power, control and instrumentation cables installed in hazardous areas where the risk of igniting the “Fire Triangle” precludes the use of naked flames and therefore heat shrink terminations or joints – manufactured from silicone rubber housing the Nexans AIN range of cold-applied cable accessories are slip-on terminations which do not require the application of naked flames to activate heat-shrink tubings.

Specially developed cable accessories including cable joints with resistance to aggressive hydro-carbons, flame and fire are available – standard resin cable joints already installed in hazardous area locations which require protection against potential fire can be over-wrapped with fire protection blankets to achieve fire resistance to the cable according to IEC 60331-11 & 21.
