Compliant Jointing & Contestable Connections


NGED Network Jointing

For contestable connections adoptable by NGED, Lovink Enertech 11kV and 33kV cable joints are specified, with the M-series LoviSil 33kV system being the Sole Approved manufacturer for NGED adoptable 33kV joints within the Independent Connection Provider (ICP) sector – this covers 33kV Straight, Transition & Trifurcating Transitions applications according to G81 NGED Document.

Where cables undergo dynamic cyclical load in high harmonic and non-linear load applications the Lovink range of cable joints demonstrate years of fault-free field performance in high temperature installations. Additionally, the cable joints are “flame-free” and therefore safe for installation in potentially explosive atmospheres as no heating source or naked flame is required for the installation.

Lovisil has been approved for use by NGED for more than 25 years and is also widely used by UKPN. It provides a dielectric strength greater than 21 kV/mm and remains fluid in service, allowing for natural movement without creating voids.

Private & Industrial Networks

Network resilience requires advanced technology solutions manufactured from highest performance materials; if high harmonics, Sine wave distortion, AD8 protection, abnormal thermal cycling, high-water table, ALE of legacy PILC or general cable failure prevention to critical 11/33kV circuit smatters to you, then talk to us.

NOTE:

If your network must overcome challenges such as:

  • High harmonics

  • Sine-wave distortion

  • AD8 water protection requirements

  • Abnormal thermal cycling

  • High water tables

  • Asset Life Extension (ALE) of legacy PILC

  • Prevention of critical 11kV/33kV circuit failures

Lovink LoviSil liquid-silicone jointing technology is one of the most robust engineering solutions available for order.


Lovink Product training with Thorne & Derrick team

LOVINK VISIT TO T&D

T&D recently hosted Lovink for a product training session focused on their latest medium-voltage jointing and connectivity solutions. The visit provided an opportunity for hands-on product demonstrations, technical discussions and knowledge sharing around installation best practices and applications.

It was a valuable session that strengthened collaboration and enhanced understanding of Lovink’s technologies and capabilities.

Thank you to Stephen Davies (Lovink Enertech Account Manager) for your emphatic presentation and roundtable with our incredible team.

glossary

What does NGED mean?

The regional Distribution Network Operator (DNO) for the Midlands, South West and Wales responsible for the operation, maintenance and development of the electricity distribution network.

What does ICP mean? 

Accredited companies permitted to carry out contestable works such as cable installation and jointing, allowing customers to connect to DNO networks.

What is a contestable connection? 

Elements of new electricity connections that can be delivered by an ICP rather than the DNO, often including civil works and jointing up to the point of network adoption.
