132kV Cable Jointing – A Showcase Page For Chris Barker (EHV Cable Jointer)
May 13th, 2021Extra High Voltage or EHV 132kV cable jointing is a highly-skilled area of electrical power engineering.
Cable jointing skill-sets are not automatically transferred up the voltage classes from 11kV to 33kV and onto 132kV.
Different techniques and technologies are applied to jointing EHV cables including polymeric, paper lead, oil, fluid-filled and transition jointing using ABB, Ericsson, Nexans, Brugg, Pfisterer Ixosil, Silec and 3M products.

This webpage has been created to demonstrate the diversity of accreditations and skills demanded in order to joint 132kV cable.
The content derives entirely from the professional workmanship of Chris Barker who is highly respected by peers throughout the UK and international EHV power industry.
Pictured : 132kV Transition Cable Joint. The image clearly shows the exceptional workmanship by EHV Jointer, Chris Barker.

A 16″ chamfer knife was used to achieve the perfect chamfering of the high voltage cable.

“If I MIG weld an aluminium core when jointing I would normally make the weld larger than the core itself. But on a cable termination the jointer must grind it down to conductor size – this requires exceptional welding skills from the HV cable jointer. Cadweld is acceptable but the jointer must open up the cable core and clean and flux every strand,” says Chris Barker.

Wood designs, delivers and maintains strategic and complex assets for its customers across the global energy and related sectors.
“Pictured below is a new build line of 46no L8(S) Towers to a new design, carrying twin Rubus conductor with a Keziah 36 fibre earthwire. The project is constructed for 400kV but will run at 275kV – the overhead line will be the main feed for the South West Scotland (SWS) strengthening works,” Jonathan informs.
Overhead Line Electrification Equipment Providers:
- Overhead Towers – Had-Fab
- Conductor & Earthwires – Lumpi
- Insulators – Sediver
- Overhead Line Fittings – Mosdorfer
- Earthwire Chairs – Tesmec
Wood have self delivered access works, foundation installation, erection and wiring, the contract has been underway for 2 years and is due for completion this month.

Lucy Electric is a leader in secondary power distribution solutions with over 100 years’ industry experience. Specialising in high-performance medium voltage switchgear for utility, industrial and commercial applications, we enable the safe and reliable distribution of energy to homes and businesses worldwide.

The photos above are from an out of hours maintenance visit by Joe Nihill. For this particular maintenance the scope of works included a fully intrusive overhaul of a 11kV South Wales switchgear board consisting of South Wales switchgear C4X Oil Circuit Breakers (OCB)Â electrical insulating oil, replacement of each breakers electromechanical protection relay testing and a transfer of operational control document.
This allowed Joe and his team to control an isolated part of the customers network safely for the duration of the works.
