Powering data centres electrical network with high-performance technologies

During the construction phase, meeting deadlines at the right cost is essential. Nexans understands on-site constraints and supports you with solutions designed to simplify installation and improve execution efficiency. Rather than just provide cables and components, Nexans solutions can outfit a complete Data Center: cables, accessories and services, a range of solutions for a reliable, efficient and sustainable electrical network.

Nexans supplies data centres with both standard and high-end quality products, cabling solutions and services which ensure fast deployment, high transmission quality, outstanding security, secure backup, easy migration, and transparent network management. We support all data centre architectures, and can do a fully customized end-to-end installation.

A complete portfolio of cables and accessories

Nexans provides one of the most complete range of cables and accessories designed to support every level of your data center electrical infrastructure. From high voltage transmission to low voltage distribution and final connections to IT server racks, our solutions are engineered to ensure reliable, safe and efficient power delivery across all environments.

• High voltage cables
  For large-scale data centers with substantial power requirements, high voltage cables are crucial. Nexans’ high voltage solutions ensure efficient power transmission over long distances, maintaining system integrity and performance.
   
• Medium voltage cables
  Suitable for connecting the data center to the primary power supply or backup generators, Nexans’ medium voltage cables are designed to handle higher power loads with safety and reliability.
   
• Low voltage cables
  These are essential for internal power distribution, connecting various equipment within the data center. Nexans’ low voltage cables are engineered for durability and efficiency, ensuring minimal power loss and enhanced performance.
   
• High temperature superconducting cables
  Providing high transmission capacity, a single High-Temperature Superconducting (HTS) cable can transmit up to 3.2 GW of power, making it ideal for the powering of hyperscale data centers. Higher current carrying capacity with less heat generated in the cables which reduced the need for extensive cooling infrastructure.
   
• Power accessories
  Connectors, joints, cable terminations are essential to ensure the reliability and safety of electrical connections across the infrastructure. Nexans offers a complete range of accessories designed for easy installation, reduced error risk and long-term performance.

High voltage cables

Hyperscale data centers demand extremely high levels of power. High voltage cables are custom-designed solutions tailored for high voltage level, installation environment, and specific constraints of each project. Nexans provides 36 kV to 500 kV solutions, mastering the whole value chain to ensure safe, performing and sustainable energy transportation.

Modernizing and upgrading existing infrastructures usually involves the installation and replacement of thousands of kilometers of overhead lines (OHL) with new generations of conductors. Reconductoring (or rewiring) of existing overhead line infrastructures with advanced conductors makes it possible to tenfold current carrying capacity without increasing footprint nor artificialization of soils. Nexans proposes a comprehensive range of advanced conductor designs allowing to increase ampacity and operation temperature by +10% to +100%.

Medium voltage cables

Medium voltage cables connect data centers to the grid, or can also connect different structures of a same site. There are several possible configurations, depending on the data centre. Medium-voltage (MV) cables can supply power directly to buildings or interconnect several structures within the same site.

Low voltage cables

In medium-sized or decentralised data centres, such as corporate infrastructure, university campuses, hospitals or edge solutions, power is generally supplied at low voltage.

For low-voltage power distribution within data centres, we provide a large range of installation cables that comply with CPR, ensuring the appropriate safety level as per requirements defined in the regulation for each application. These cables ensure a reliable power supply to various pieces of equipment, including:

• servers and IT infrastructure
• lighting systems
• cooling systems
• power sockets and auxiliary equipment

Low fire-hazard cables constitute the best line of defense against fire in all types of buildings and infrastructures. They significantly delay the propagation of flames, thus gaining precious time for evacuation and fire-fighting. Thanks to their advanced reaction-to-fire properties, they reduce opaque smokes and acid gases to a minimum, securing a safe escape with the best possible visibility. Data centres must also remain operational during a fire. Nexans addresses this challenge by offering a fire safety range compliant with the most demanding international safety regulations. Our low fire-hazard cables incorporate technologies to minimize fire spread and the release of corrosive smoke.

For battery interconnections in data centres, two complementary cable ranges are available to meet different installation requirements.

High-temperature superconducting cables

High-Temperature Superconducting (HTS) cables offer a compelling solution that can radically simplify power infrastructure, reduce costs while unlocking a step change in how data centres transmit and distribute power and redefining the overall infrastructure design. With zero electrical resistance, ultra-high current capacity and a compact footprint, HTS cables can radically simplify power infrastructure, reduce thermal loads and support the broader goals of sustainability and electrification.

Nexans HTS cables cover the full range of voltage levels, from HV transmission and MV distribution networks to LV power distribution within data centres, providing a scalable solution for every stage of the power chain.

Nexans can also supply also the entire range of Superconducting accessores (Terminations and joints).

Power accessories

Power accessories (connectors, cable terminations) are essential to ensure the reliability and safety of electrical connections across the infrastructure. Nexans provides a complete range of accessories designed for easy installation, reduced error risk and long-term performance. Our solutions support faster deployment and help secure connections at every stage of the project.
