Support power cable systems across the lifecycle

NKT Grid Solutions brings together planning, cable system engineering, and project preparation. From there, we support projects through delivery and into long-term operation. The exact scope depends on the grid, voltage level, route conditions, and interfaces. For existing systems, asset condition and operating requirements also play an important role.

Our experts consider the cable system as a whole. Cables and cable accessories need to work together, while installation requirements and interfaces must also fit the wider system. This integrated approach supports grid expansion and infrastructure upgrades, as well as renewable integration and the continued operation of existing cable assets.

Develop and deliver power cable system projects

Energinet service agreement onshore offshore

New grid infrastructure must be planned around network requirements, connection points, routes, interfaces, installation conditions, and operating objectives.

Subject to the agreed project scope, NKT can support project planning, cable system engineering, project preparation, installation, testing, commissioning and more. This may include coordinating cable system components and field activities for high-voltage AC (HVAC) projects. NKT also supports the deployment of new cable systems for grid expansion and modernisation. The exact responsibilities, technologies, voltage levels, and project boundaries must be defined for each project.

Manage cable systems during operation

Cable system requirements continue after commissioning. As assets age and grid needs evolve, monitoring and maintenance can help identify where further intervention may be needed.

NKT’s lifecycle services help customers assess cable system condition and plan maintenance. When repair, replacement, or modernisation is required, our experts can support the next steps. Asset information, extensive cable expertise and field experience are brought together to support informed decisions.

Plan for the full cable lifecycle

Power cable systems require different forms of support as they move from installation and commissioning into operation, maintenance, repair, and eventual replacement or decommissioning. Explore NKT’s specialist lifecycle services for cable installation, power cable monitoring, testing, maintenance, repair, and related asset activities.

Support high-voltage AC grid infrastructure

HVAC cable systems are central to many modern power grids. They support transmission and urban grid connections as electricity demand grows and more renewable generation is integrated.

NKT supports these projects from planning and engineering through to installation and commissioning. Our experts can also support maintenance, and repair once the system is in operation.

Technical questions about power cable systems

A high-voltage cable system must coordinate the cable design with joints, terminations, connection equipment, route conditions, installation methods, civil interfaces, and commissioning requirements. Changes at one interface can affect the wider system and project execution. NKT combines cable system engineering with installation and commissioning expertise, helping customers coordinate these interfaces within the agreed project scope.

Turnkey delivery for a HVAC cable system can include planning, engineering, project preparation, installation, testing, and commissioning. The precise scope depends on the grid connection, cable route, system interfaces, and agreed division of responsibilities. NKT can bring these activities together within one project delivery scope and continue supporting the installed cable system during operation and maintenance.

Cable system condition may be assessed using available operating data, inspection, testing, condition monitoring, maintenance history, and engineering evaluation. The appropriate approach depends on the cable design, accessories, age, operating conditions, and available asset information. NKT combines monitoring and technical assessment with field experience to help customers plan maintenance, further investigation, repair, or replacement.

The decision depends on the nature of the defect, asset condition, system compatibility, grid requirements, outage constraints, and the technical feasibility of intervention. Repair may address a defined fault, while replacement or modernisation may be appropriate where wider system requirements have changed. NKT supports existing and legacy cable systems with engineering, maintenance, repair, replacement, and refurbishment activities, subject to the installed system and agreed scope.

Preventive maintenance uses planned inspection, testing, monitoring, and service activities to identify changes in asset condition before an intervention becomes urgent. This allows to plan for mitigating actions – avoiding unplanned, lengthy and often costly outages. The maintenance strategy should reflect the cable system, accessories, operating conditions, criticality, and available condition data. NKT connects preventive maintenance with monitoring, engineering assessment, and repair capabilities to support long-term operation of existing power cable systems.
