Onshore Cable Service

Best performance, regardless of the cable type

To minimise power outages and ensure uninterrupted supply, you need a reliable service partner that focuses on the specific challenges presented by cable systems. This is the only way to ensure steady and sustained functionality. 

NKT relies on its extraordinary wealth of experience for the production and maintenance of a wide range of insulation technologies. From extruded (XLPE) and mass-impregnated cables to the legacy gas-pressure or oil-filled cables – still common in our cities – we know the technical requirements for every cable type. This makes us the ideal provider of onshore service products not only for new cable technologies but also for cable systems of older standards.

Cable Services Core Competence: Repair Preparedness

Repair Preparedness

ADVANTAGE: Skilled resources on standby shorten the reaction time and facilitate the fastest possible return to normal operation.

Preparation is key to successful repair operations. We can tailor a preparedness plan for you, outlining the data, permits, certificates, contacts and repair scenarios that are necessary for repairs to be performed swiftly and safely. 

Cable Services Core Competence: Monitoring Solutions

Monitoring Solutions

ADVANTAGE: Preventative maintenance and repair increases the system's service life.

It must be possible to remotely check the cable’s health to make sure the permissible cable load is adapted to changing conditions at all times. We also help to identify the risk of future outages.

Cable Services Core Competence: Maintenance


ADVANTAGE: Improved system service life, minimised risks.

Sound experience and expertise are necessary ingredients for high-quality cable maintenance. This must be carried out regularly to ensure reliable operation. At NKT, we offer a comprehensive set of maintenance procedures, including inspection, cleaning, checking of consumables, measuring, refilling, data collection and reporting.

Cable Services Core Competence: Spare Parts

Spare Parts Management

ADVANTAGE: Ensures availability of necessary spare parts.

Should a cable failure occur, it is important to have all the necessary spare parts readily available. NKT has a structured method to ensure that our customers' spare parts inventories are always updated. This is crucial in case of emergency, as the condition of some parts deteriorates over time. Our service team checks whether your stock is sufficient, focusing mainly on cables and cable accessories. Based upon this inventory, we can stock and replace the necessary parts for you.

Cable Services Core Competence: Resources on Call

Resources on Call

ADVANTAGE: Answers to general queries and quick support in initiating first measures.

Time is of the essence in the event of a cable failure. Our resources on call service gives our service level agreement (SLA) customers the guarantee that the right resources will be available 24/7 to assist in the event of an accident. Because the price is fixed, you don’t have to worry about price negotiations during a cable failure. You are guaranteed telephone contact with one of our cable experts within 30 minutes of reporting a problem.

Cable Services Core Competence: Fault Location

Fault Location

ADVANTAGE: Reduces repair time.

If necessary, a repair operation can be mobilised immediately after a call is received. NKT’s service vans are equipped with tested and calibrated equipment, enabling our skilled and experienced service engineers to make any necessary field measurements. Our service engineers use and combine different methods to search for and locate the section of cable where the fault has occurred.

Cable Services Core Competence: Cable Jointing and Termination

Cable Jointing and Termination

ADVANTAGE: Large pool of in-house construction supervisors and cable engineers.

Cable jointing is a craft that takes many years to master, especially when it comes to working with paper-insulated cables. Our experts are sourced from our in-house installation department, which means that all of their time is devoted to jointing and termination work. We deliver complete jointing solutions that - apart from the expertise of our personnel - include all the equipment necessary for jointing.
