Transition Joints Trusted by DNO’s for Decades
Proven performance matters
As electricity networks evolve, DNOs are continuously connecting new cable systems to existing infrastructure. Because network renewal is usually phased rather than complete, transition joints remain a critical part of medium-voltage asset management.
For utilities, the priority is simple: reliability. A transition joint must perform consistently for many years while connecting different cable generations, insulation technologies and installation standards.
Why standardisation reduces risk
Many DNOs aim to standardise components across their networks. Using proven jointing solutions helps reduce installation variability, simplifies training and increases confidence in long-term performance.
This is particularly important at transition points, where older PILC cables and modern XLPE cables meet. These interfaces often represent some of the most critical points within the distribution network.
When a transition joint solution repeatedly demonstrates reliable field performance, utilities often continue using it as part of their long-term renewal programmes.
Confidence built over decades
One of the strongest indicators of reliability is repeat adoption. Across Europe and beyond, many utilities continue to include established transition joint solutions in their annual maintenance and network replacement programmes.
National Grid Electricity Distribution (NGED) in the UK, for example, has relied on Lovink cable jointing solutions for many years. The partnership recently marked 25 years of cooperation, illustrating the value utilities place on proven long-term performance.
A similar focus on reliability can be seen at Dutch DNO Enexis, which once again selected Lovink solutions for its network, emphasising continuity and dependable operation.
The same challenges exist elsewhere in the world. Utilities such as Edenor must also connect legacy and modern cable systems while maintaining secure and reliable power distribution.
Supporting phased network renewal
Most ageing cable networks cannot be replaced overnight. Instead, utilities modernise their infrastructure step by step, creating an ongoing need for reliable connections between existing and newly installed assets. Transition joints therefore play a crucial role in enabling network modernisation without compromising continuity of supply.
Reliability that stands the test of time
The transition joint solutions that remain in use for decades are rarely chosen because they are the newest available. They are chosen because they have demonstrated reliable performance in real-world networks, year after year. For many DNOs, that long-term track record is what turns a component into a trusted asset.
