66kV Cable Jointer Training – A Question Of Competency Not Familiarisation
January 10th, 2018Uploaded By: Chris Dodds - reading time 5 minutes

66kV Cable Jointer Training
The wait is over.
A responsible Cable Jointer Training Centre professionally committed to safeguarding the industry standards of their trade while providing client recognised and accepted certification. Protecting the present while nurturing the future generation of Jointers.
Helping our Cable Jointers climb the voltage ladder from 11kV to 33kV and 33kV to 66kV.
Carefully pre-qualifying prospective trainees to vet for existing levels of skill and experience – passionately preserving the integrity of the Craft against the spate of underskilled labour flooding the jobs market, undermining day rates and undervaluing standards.
A Jointer Training Centre competent in itself to issue Competency Certification to course attendees. Not Familiarisation. Competency. There is a world of difference.
I can “familiarise” myself with aeroplanes and even book a flight simulator experience but that does not provide me with “competence” to pilot an Airbus A380. Flippant? Not really.
The virtual is not reality nor does 4 days in a Training Centre classroom environment equip jointers with the required expertise to work bent-double, in a muddy hole, in the rain wrestling with 11kV cables.
Electricity is dangerous, it kills – failure to understand the complexities of jointing medium and high voltage cables endangers life. Likewise, working and jointing on live low voltage mains cables requires effective cable jointer training courses to support industry health and safety.
Interested? You Bet! OK, what next?
Read on to discover more about the soon to open new Nexans Training Centre.

Nexans
Nexans Training Centre will be fully equipped to provide practical and theoretical training for Cable Jointers on all aspects of Medium Voltage Cable Accessories. Jointer training courses can be individually tailored to meet the specific requirements of the client. Nexans are intently focussed on the criticality of jointers understanding and perfecting preparation of MV-HV cable using appropriate cable jointing tools.
The newly located and upgraded Jointer Training Centre will be fully operational in October and Nexans new certification will form part of a fully signed Competency Card which consists of a 3 part certified documentation and ID card.
All test-pieces completed by course attendees are tested for AC withstand and partial discharge and in order to obtain a “pass”, the tested installation should have pd levels <10pC. This is conducted on the day of training using Nexans state-of-art test lab.
Training can cover Nexans Joints & Terminations using heat shrink, cold shrink, slip-on and Euromold Connectors.

66kV
Ambitious and forward-thinking 33kV Jointers are already searching for opportunities to add 66kV Jointing Competency to their skill-set and CV’s.
Cable jointers employed to joint and terminate 66kV cables on offshore substation platforms must demonstrate Competency.
High quality training is key to achieving sufficient skillmanship when working on high voltage cable systems and can unlock career progression opportunities.
Back in 2013, The Carbon Trust, as part of its Offshore Wind Accelerator (OWA) launched a competition to fast track the development of new 66kV cables to be used in the offshore wind and renewable industry.
Moving on up from 33kV to 66kV necessitates retraining and Competency Certification for Cable Jointers working on the the termination and jointing of 66kV cables.
OWA developers including DONG Energy, E.ON, Mainstream Renewable Power, RWE Innogy, ScottishPower Renewables, SSE Renewables and Vattenfall representing 77% (36GW) of the UK’s licenced capacity.
Moving from 33kV to 66kV arrays and subsea cables presents a number of benefits, including the ability to connect more turbines per string and the possibility to design inter-array networks in ring layouts rather than in radial strings, thus increasing reliability.
OWA managed a number of studies investigating these potential benefits, which eventually led to the launch of the 66kV cable qualification competition.
Fast forward to 2016 and Nexans have supplied inter-array and export cables for the world’s first 66kV offshore wind farm.
Clearly, 66kV is the future for renewables.

Nexans 66kV inter-array high voltage cable systems provide the subsea connection between the offshore turbines and the onshore grid for the Blyth Offshore Demonstrator Wind Farm Project. With offshore wind turbines growing in size, the new 66kV Nexans cables and cable connectors are improving the lifecycle cost-efficiency compared to 33kV systems.


Some recommendations for 66kV Jointers Tools
Register Your Interest Today
Confirmed demand for course attendance is exceptional – should you be a Competent 33kV Cable Jointer interested in pre-booking or registering “early-bird” interest for the next course please email your expression of interest today. Course dates, content and costs are to be finalised in coming months.
Successful completion of the 3 Day Jointer Training Course will equip attendees with the required Competency certification to work offshore in the wind energy sector.
Course Details & Our Requirements
The course duration is 3 days at Nexans Jointer Training Centre, Castleford UK – all attendees must provide their own Jointers Tools and be skilled at 33kV cable preparation. Jointers will be expected to undertake the preparation and stripping of the 66kV cable prior to installation of the cable joint and separable connector – this Course does not certify on the basis of cable preparation. Once cable joint and connector have been installed the test piece of 66kV cable will be subjected to energisation in the test laboratory and AC withstand an Partial Discharge test. This will determine PASS or FAIL.
Typically, the training course aim is to achieve 66kV Competency for the Cable Jointer currently experienced in terminating and testing 33kV cables to Interface C switchgear bushings and installing Slip-On type termination to the MV transformer end on onshore or offshore projects.

Cable Joints LV Low Voltage | Cold Shrink | Heat Shrink | Resin for Offshore Cables
3M Scotchcast Offshore Cable Joints
The 3M LVI3 range of Scotchcast Cable Joints utilising 3M 1402FR Resin are extensively specified for the jointing, splicing and repair of offshore cables in the oil and gas industry up to 3.3kV – this includes low voltage power, control and instrumentation cables installed in Zone 1 & Zone 2 hazardous areas designated according to ATEX Directive.
For medium/high voltage power cables there is a choice. MV- HV Cold Shrink joints are available with cold shrink outer protection jacket or encapsulated with a cable joint shell and filled with Scotchcast 1402FR resin to provide additional protection against aggressive and corrosive chemicals, oils, gases and MUD.
Extreme Temperatures
3M LVI3 cable joint kits should be installed in temperatures above freezing point to ensure that the Scotchcast resin is properly mixed and cured (the resin can be warmed by the cable jointer in a vehicle if required). Once installed the cable joints are stable at lower temperatures down to -40°C.
High Voltage Joints
Thorne & Derrick have produced custom specification offshore 33kV cable joints to repair and connect submarine power cables for land underground installation – typically the straight joints would be installed on the cable deck of an Offshore Substation (OSS) located on an offshore wind farm.
The cable test requirements were in accordance with IEC 60502-4, rated or operating voltage 19kV/33kV and maximum voltage 33kV – briefly the 33kV offshore cable specification would include XLPE insulation, extruded bonded semi conductive compound, water blocking tapes, metallic screen and a single layer of galvanised steel wire armours filled with bitumen.
