YOUR CHALLENGES
Data center power challenges: from constraints to competitive advantage
Data center operators must add power capacity on saturated grids, protect uptime, control energy costs and meet stricter ESG requirements, all at the same time. Behind each of these challenges sits the electrical architecture, which has become a strategic lever for resilience, energy efficiency and long-term performance.
Power & Scalability
Prepare the electrical infrastructure for growing loads and AI-driven power densities.
Reliability & Uptime
Reduce electrical risks at every connection and protect critical operations.
Cost effectiveness
Balance CAPEX and OPEX to optimize value over the whole lifecycle.
Sustainability
Cut energy losses and embodied carbon to support ESG and reporting targets.

POWER CHAIN
Cables and accessories across the data center power chain
A data center’s power travels from the grid connection to the IT racks through several voltage levels and conversion stages. Each link requires cables and accessories suited to its voltage, load and safety constraints. Nexans covers the entire chain with a single portfolio.
01 Grid connection
High- and medium-voltage cables and accessories linking the site to the grid substation.
02 MV distribution
Medium-voltage cables, joints and terminations distributing power across the campus.
03 Transformers to switchboards
Low-voltage power cables carrying high currents from transformers to main switchboards.
Choosing the right cables and accessories at each step is key to reliability: most medium-voltage failures occur in cable systems, and particularly at joints.

TECH SOLUTIONS
Breakthrough technologies for next-gen data centers
HTS superconducting cables
High-temperature superconducting cables power hyperscale and gigawatt-scale data centers with near-zero transmission losses, in a much smaller footprint than conventional cables.
NET-ZERO ENABLERS
Cutting carbon emissions linked to data center cabling
Most of a power cable’s carbon footprint comes from electrical losses during operation, so the biggest lever lies in design and cable sizing. Nexans complements it with low-carbon cables, certified environmental data for Scope 3 reporting and cable recycling.
