If you’re a Jointer of cables you better read this.
Last week, I had the pleasure to meet Duane Thompson (Founder & Managing Director) of Networked Professionals and learn how he and his team are quickly positioning their recruitment agency at the forefront of the Cable Jointing sector of the electricity industry.
In the following Post we introduce this innovative recruitment agency dedicated to placing and supporting Jointers (LV MV HV) with payment applications settled early and regular work flows while sheltering them from the chill winds of sllooowww payment from contractors.
Who Are Networked Professionals?
Networked Professionals are a global recruitment business dedicated to senior and middle management recruitment in three specialist sectors – Renewable Technology, Transmission & Distribution and Sales, both in the U.K and Internationally.
Networked Professionals Core Sectors

The T&D team are specialists working across Electricity, Water, Gas, Transmission & Distribution and Rail projects, finding niche skills for transmission owners, TSO’s, network operators, multi-utility operators, contractors, service contract providers, principle contractors design consultancies and OEM’s.
Networked Professionals Deliver Contract & Staffing Solutions Across the Utilities Sector
Quality Assurance
Networked Professionals are able to meet all of the niche requirements of their clients because of extensive sector experiences in addition to a solid infrastructure and a parent company that has been trading strongly for over 30 years.
Networked Professionals understand that it can be frustrating working with a recruitment agency that doesn’t understand your requirements and working practices fully.
Building strong relationships with clients is the number one goal.
NP believe that every experience a client has with them should be of the highest standard, which is why they will provide a smooth, professional transition within any placement period and rigorously vet our candidates. This approach has enabled them to secure clients within large organisations.
Transmission & Distribution
Networked Professionals are responsible for delivering permanent and contract staffing solutions throughout Europe, Middle East, Asian, Americas and Africa across the Transmission and Distribution finding niche skills for the following clients:
Currently supplying candidates throughout the Transmission & Distribution industry to clients who specialise in MV-HV switchgear substations, new connections, transformers and cabling of various voltages – including the installation of 11kV/33kV joints and terminations. Dealing with candidates from all levels i.e. cable jointer, commissioning engineer to Director.
Their policy is to meet the individual needs of each client by using a wealth of experience and knowledge gained with the capability to meet all of the niche requirements of the client.
Networked Professionals pride themselves on the delivery of high calibre candidates along with continuous feedback for candidates.
Most recently they have developed great contracts with distribution suppliers in the south and the Midlands from which work can be ad-hoc days to 6 -12 month contracts. They ensure smooth payment terms which help with smaller teams just starting out that can’t take the usual 45 day payment terms.
A Satisfied Client
Their most recent success story of this is Lee Richards, former Project Manager for Dragon Infrastructure. With their help sourcing work and short payment terms he was able to take the leap from PAYE employee to Director of his own successful cable jointing contracting company LR Power Services.
Lee Richards is a 33kV Competent Jointer with diverse cable jointing skills covering LV (Consasc Wavecon | Live Cable Jointing), 11kV (Triplex PILC) up to 33kV – this encompasses manufacturers such as Lovink, Nexans Euromold, Tyco and Prysmian.
If you currently have a client with payment terms that don’t work for your pocket but you wish to continue working with them consider introducing them to Networked Professionals – their services will ensure that not only will they be happy by little to no change in the bottom line charge for them but the client will be a happier contractor getting paid for your hard work much sooner.
Networked Professionals currently supply candidates throughout the Renewable Energy Industry, that specialise in all aspects of Wind Power
A word from Duane Thompson Co-Founder & Managing Director:
If you require staff for sub-contracting work nationally or internationally Networked Professionals can support your needs.
With our partnerships with generic and specific jobs boards and of course Thorne & Derrick we can support the labour and manning side of your company; whether this be one or two candidates to the supply of staff for an entire project the team at Networked Professionals is just on the other end of the phone to support you.
We have set up Networked Professionals to service the burgeoning talent requirement for transmission and distribution, renewables and infrastructure internationally and I am confident that our dedicated team will quickly establish the brand as a front-runner for recruitment in these sectors, with the support of the Solutions infrastructure.”

Nexans Fire Resistant Cable Blanket is a cable joint protection cover with belts designed to be used with LV, MV or HV joints and cables in applications where low smoke emission and resistance to fire is needed. The Nexans Fire Protection Kit is designed for easy installation due to the belt design, open shape and “wrap-around” installation application.
The fire resistant cable blanket is designed with different layers of material to withstand high temperatures and is suitable to protect low, medium and high voltage cables from the destructive effects of fire. No specialist tools are required to install the fire blanket – simply manually lift, tighten and fasten the lightweight blanket onto the cables.
All materials included in the Nexans Fire Protection Kit are classified as low smoke emission and halogen free.
Protecting LV MV HV Cables & Cable Joints Against Fire
Nexans NX Fire blanket has been approved by ENEL and is available in different sizes and lengths upon request to suit cable outside diameters 20-300mm.

Used to protect both onshore and offshore cables, including offshore cable joints where marine and offshore cables and joints in fixed installations for power circuits, emergency lighting systems and fire alarm systems must provide continued service in fire conditions.
The product is cold-applied without need to resort to “hot-work” permit applications to carry out cable repair, jointing or protection in potentially explosive atmospheres or hazardous area locations.
Suitable to provide fire protection to fire hazard safety cables in the rail industry – including sub-surface, tunnels or station level including power cables for low voltage lighting, fire detection, emergency, signalling and auxiliary circuits.
The fire resistant blanket has been tested according to the following international standards:

Here, high voltage substation cables are shown connected and terminated into switchgear using 33kV cable terminations.
The copper earthing tapes are used to bond all of the cable glands together which are providing mechanical retention to the 33kV high voltage power cables.
The earth tapes are clamped and attached to the substation earthing system as they are insulated from the 33kV cable box and high voltage oil-filled switchgear. The whole bank of HV switchgear is insulated from the ground and has its own earth which runs through a Current Transformer (CT) for protection reasons – the separate ‘frame earth’ is painted green in the photograph below. The stand for the cable cleats was also bonded to the substation earth. As there is a steel sandwich plate fitted to the front of the wooden cable cleats the threaded bar used is stainless steel to avoid circulating currents.
Client specified expanding foam has been used to seal the substation cable ducts within the high voltage substation – outside the substation the 33kV cable ducts were effectively sealed using a specified system to provide certain protection against water ingress and gas migration using recognised systems such as the CSD RISE duct seal or Filoform Filoseal re-enterable cable seals.
The insulating oil is usually heated before the high voltage cable box is dismantled by venting it above and heating with halogen heaters.
The 33kV cables were stripped using the correct cable jointing tools – the PVC cable sheath was thoroughly stripped from the high voltage power cable using the Boddingtons “plough” type sheath stripper. The cable jointer then removed the XLPE insulation cleanly and without damaging the cable using Alroc LH2 tool suitable for cable stripping HV cables up to 60mm.
Finally, Alroc CWB 18-60 tool was used to remove the bonded semicon from the cable – the “blue tool” manufactured by Alroc is preferred by jointers for working on medium/high voltage power cables where a clean square cut of the semicon without jagged finish is vital to the long term reliability of power cable performance.
Poor cable jointing skills with respect to MV-HV cable preparation can create future cable failure potential – it is critical a skilled jointer uses the correct cable tools to prepare MV-HV cables before installing joints, terminations or connectors up to 33kV.
Comments from fellow HV cable jointers:
Jimmy Nicklin: “Nice job Craig Kilkenny. I did a nine bank of these 15 years ago and is quite the breakdown and remake to do.”
Dean Wilson: “Nice neat work Craig Kilkenny and yes I agree Jimmy Nicklin it’s getting the old oil out that’s a job in itself!”
Andrew Brezovszky: “Very neat 33kV cable terminations !”

A series of How-To videos for repairing, jointing and terminating cables using 3M Cold Shrink & Scotchcast products.
This video by 3M Electrical shows the benefits of using 3M Cold Shrink compared to heat shrink cable accessories to insulate, joint, repair and terminate cables.
3M cold shrink tubes utilise a unique cold applied delivery system which is designed to make cable jointing, insulating, termination and abandonment as simple as possible without any of the inherent workplace risks associated with “hot-working” and using naked flames to activate heat shrink type cable accessories.
Cold shrink reduces the risk of damaging XLPE cable insulation caused by scorching or over-heating of the cable by the jointer. No cooling time is required before energising cables.
Installation is fast and an easy one-step installation process:
➡ See How To Use Cold Shrink Tubes.
3M Tubes – available in EPDM Rubber or Silicone
Depending on the application cold shrink is available manufactured in EPDM Rubber or Silicone – contact us to discuss your application.
Cold Shrink creates a static and stable cable seal that does not expand or contract with the cable under thermal cycling of LV-HV cables, potentially leading to the creation of voids between the cable accessory and the cable which could lead to a joint or termination failure.
Cold Shrink – invented by 3M over 40 years ago and now the preferred technology for heat-free jointing, terminating, sealing and abandonment of LV HV cables
We hope you find this video informative and educational, contact T&D for technical support, quotations and stock availability for 3M Cold Shrink.
* Data based upon U.S. failure data of U.S. manufactured 3M Cold Shrink Medium Voltage Cable Accessories between 2009 and 2012.
Should you require support about selecting the correct 3M Cold Shrink product range for use with low, medium or high voltage cables please contact us – a complete range of Cold Shrink cable joints and terminations is available for MV-HV cables, including 11kV/33kV.
