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) 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.

Cable stripping dimensions should be carefully observed by the MV cable jointers and the correct cable jointing tools used to remove sheath, insulation and semi-conductive screens.
Andy O’Malley commented “Nice clean tidy work area – silicone tape applied at the bottom of the cold shrink termination.”

This vulcanised type cable joint is smooth profile preventing “snagging” of the 11kV joint during the reeling process – there is absolute minimal increase to the overall outside of the cable diameter despite the joint.
“The cable joint was completely taped using a variety of 3M Scotch vulcanising tapes and the outer sheath was re-instated using Prysmian rubber tape. A complete cable joint carried out on a stacker,” said Corey.

High Voltage Lead Sleeve Y Joint
May 11th, 2021This striking splicing image demonstrates traditional cable jointing techniques requiring exceptional manual dexterity, acute concentration and advanced skill levels.
Modern polymeric cable jointing is now dominated by cold-shrink, click-fit and push-on type splices which are frequently alleged to have de-skilled the Jointer by introducing simplified installation processes.
Whether you agree or disagree, no jointer can dispute that “old-school” jointing skills demand the highest levels of professionalism, knowledge and ability:
- Sweated ferrules
- Hand applied oil tapes
- Plumbed lead sleeve
- Compound filled
