11kV EPR Triplex Cable Joints Using Lovink Enertech Medium Voltage LoviSil Cable Joints
May 13th, 2021Lovink Enertech LoviSil cable joints are developed on the basis of fluid silicones, a technology that can boast 25 years proven field experience with an extremely low cable joint failure rate.
Due to the construction and characteristics of the silicone-based insulation material, the Lovink LoviSil medium voltage cable joint is particularly suitable for applications with both polymeric and paper-insulated cables – the ideal transition joint, but also the perfect universal straight through joint.
Lovink LoviSil cable joints have been adopted by Western Power Distribution (WPD) due to their acknowledged low failure rate for the jointing of 11kV EPR cables.
11kV Lovink LoviSil Cable Joints (WPD Approved)
The cable jointer utilises mechanical shearbolt connectors for fast and simplified jointing of conductors without resort to hydraulic crimping tools and die sets.
The white inner casing is a polyester material which is bolted together and then sealed around the outside lip with a poly type resin which is very important to get level. The connections inside the case are filled with LoviSil dielectric silicone fluid. The outer red casing is filled with ProtoSil polyurethane resin.
The cable jointed on this occasion was 11kV Triplex 185sqmm with EPR insulation and bonded screen (WPD Specification).

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.

“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.
