We supply a large selection of harmonized cable products

NKT is proud to supply a wide variety of high quality cables and wires, with harmonised wires and cables forming a core part of our business. With our partners, customers and facilities spread in numerous countries around the globe, we have an obvious interest in facilitating the ease of integration between various systems in different countries.

Harmonised wires and cables allow us to achieve this by increasing compatibility between different countries and helping them to work together on various projects, as well as boosting and increasing free trade. Accordingly, we manufacture cables compliant with CENELEC, the European Committee for Electro Technical Standardization. CENELEC countries form a sizeable market alone, with 31 countries signed up and a further 11 neighbouring countries classed as affiliates. CENELEC aims to encourage companies to voluntarily unite for the same technical standards to not only develop the European Single Market but also expand borders for trade and create new markets, an important aim for our company and one we are proud to be a part of.

Outside the standards of CENELEC, NKT also manufactures its cables according to its own stringent controls, ensuring that our customers receive the highest quality products and solutions available on the market.

What are harmonised cables?

Harmonised cables are specially-made cables bearing the 'HAR' mark, which help to minimise the difference in electrical systems in various countries around the world. This allows for a greater degree of compatibility, particularly with projects spanning and involving numerous countries, and helps to increase the customer base for cables and expand free trade while creating new markets.

NKT has a long and proud history and tradition of manufacturing cables made to the highest international standards, and has an extensive product line of harmonised cables to help facilitate this.

Control and monitor grid load and provide effective damage prevention

Could the Valcap® power cable monitoring software system cut your business costs and improve electrical grid safety for you? This innovative solution offered by NKT works in partnership with your existing cable software to give you better control over efficiency, performance, safety and management of power networks.

Load restrictions of submarine cables due to thermal limits are a significant problem if the required energy cannot be transported. Especially wind farms with high load variation due to varying wind situations require the flexible usage of the available cable capacity. If windmills have to be shut down, significant cost is involved due to lost revenues. On the other hand the damage of submarine cable due to overheating also leads to huge cost for cable replacement. The VALCAP® Load Management System is a combination of hardware and software that uses temperature information of power cables acquired by fiber optic temperature measurement together with current load information to utilize the full capacity of submarine cables. Automatic warnings are created if a cable could be at risk of being damaged due to high load situations.

Damage to underwater cables due to shipping activity is a significant global problem. Repairs to damagedcables are very expensive and availability of suitable repair vessels is difficult to guarantee. The problem is likely to get worse as more cables are installed for offshore wind farms and marine turbines. The VALCAP® Security Monitoring System is a software application that is using multiple functions such as acoustic monitoring, to safeguard against and warn as well as detect possible damages. In case a cable may be at risk, the system automatically provides a warning to prevent possible damages.

With our vast experience in power cable monitoring, we also provide specific monitoring services in case of special requirements. Our experts will evaluate your needs together with you in order to find the best solution to your individual challenge. In doing so, we always focus on quick and efficient solutions while always keeping long term customer value in mind.
