Intéressé par nos solutions ?

Nous soutenons les compagnies d'électricité et les gestionnaires de réseaux de transport en les aidant à remodeler leurs réseaux et à les rendre plus intelligents et plus fiables.

Des solutions à l'épreuve du temps pour des réseaux plus intelligents

In the electrification value chain, transmission and distribution grids are essential links to support increasing energy demand and our day-to-day power usage. To ensure continuous energy supply, avoid costly power outages and shutdowns, and foster the development of renewable energy, High Voltage power transmission systems need to accommodate and connect an ever-wider variety of power sources, while ensuring reliability all along the line.

We can support you in upgrading specifications in the smartest possible way to assure more sustainable system characteristics. This encompasses everything from design, delivery lengths, dry accessories, line losses, and installation.

Nexans can interconnect your land and sea assets and meet all your requirements with our complete range of services and solutions. This includes numerous digital applications, such as electrical asset management software and advanced detection and monitoring systems. We can also propose unique innovative solutions, such as superconducting systems especially designed for dense urban environments.

Forte compréhension du client, proximité et soutien

Nexans can support all of your HV projects and cabling requirements in a reliable, flexible and cost-effective way, through product innovation, expanded services, optimization, and proven approaches to realizing economies of scale.

Gradually reshaping transmission grids, to make them even more flexible and smarter is essential to allowing higher transmission capacities - up to 2GW in a few years. As offshore and onshore power generation increases, so should the robustness of the entire system.

In this new electrified world, everything from vast power plants, large windfarms and solar parks to all ‘micro-systems’ (such as small thermal and solar power installations) need to be coupled with new, high capacity storage and interconnection technologies.

Clear understanding of TSO’s and DSO’s challenges and expectations
Longstanding relationships
Ability to support customers at early stages of projects
Strong capability to support customers globally and locally, with dedicated teams

Assurer la fiabilité et la stabilité du réseau et réduire les risques liés au transport d'électricité

Traditional methods of operating a power utility - split into generation, transmission and distribution parts - are being replaced by more integrated approaches. And this deregulation is continuously pushing for more interconnections and requires better monitoring of the network.

In this context, ensuring High Voltage transmission reliability and grid stability is essential from a technical and economic point of view. Connection joints and the best possible accessories, along with robust basic components, are crucial to maintaining and improving this reliability and prevent outages. But if shutdowns occur, anticipation and quick repairs are all the more important.

You can de-risk projects and ensure monitoring, fault tracking and repairs are handled as rapidly and efficiently as possible thanks to our advanced business continuity capabilities and land transmission offerings.

Safest overhead and underground solutions designed, tested and commissioned in house
Reliable installation partners
Complete business continuity solutions including asset monitoring, preparedness and crisis management
Dedicated teams able to give advice and implement fault finding, preventive or curative maintenance in your networks
24/7 emergency repair agreements
Reduced and constantly monitored carbon footprint

Nos conducteurs innovants accompagnent la transition énergétique

En développant et en construisant des réseaux nationaux de transport d'électricité robustes, les opérateurs s'efforcent de trouver des solutions responsables et économiquement efficaces, en essayant de limiter la construction de nouvelles infrastructures : ils préfèrent optimiser et mettre à niveau l'infrastructure existante lorsque cela est possible.

Là où des lignes aériennes existent, ils préféreront installer des conducteurs supplémentaires ou nouveaux afin de transmettre plus d'électricité.

Partant de ces exigences clients pour des capacités toujours plus importantes à transporter, nos équipes dédiées ont développé une gamme complète de lignes aériennes, nécessaires à la sécurisation des réseaux haute tension. Cela permet aux opérateurs de préserver leur infrastructure existante de pylônes tout en remplaçant les conducteurs par de nouveaux intégrant les dernières technologies de transmission.

Formation Haute Tension

Nexans considère que la formation continue est primordiale pour la sécurité des chantiers Haute Tension.
La santé et la sécurité de ceux qui interviennent sur les chantiers - prestataires ou collaborateurs - sont des priorités fondamentales.

Le Centre de Formation Haute Tension de Calais, créé en 2006, a pour vocation de former tous les acteurs de la Haute Tension de 60 kV à 500 kV ... et plus
Plus de 180 sessions de formation déployées pour ses collaborateurs ainsi que pour ses clients à travers plus de 20 pays
Des formations standards ainsi que des modules dédiés et sur mesure en fonction des besoins. Ces formations peuvent être théoriques et/ou pratiques.
Les facilités nécessaires sont à disposition sur notre site de Calais mais le HVTC a aussi la capacité de se projeter sur des sites de travaux ou chez nos clients
