In February 2026, Nexans announced a seven-year framework agreement with Enedis for France’s medium-voltage grid modernization. The project supports 20 kV underground networks, renewable-energy connections, EV-charging infrastructure, and the burial of power lines.
For cable buyers, the key lesson is not the contract value. It is how cable specifications are changing: higher-capacity aluminum conductors, stronger direct-burial designs, stable supply, and documented environmental performance.
WHAT GRID MODERNIZATION CHANGES FOR CABLE BUYERS
Distribution networks must connect more renewable generation, charging infrastructure, and industrial loads. A cable is no longer selected on price per meter alone. A successful MV specification balances electrical capacity, installation conditions, conductor material, protection, delivery reliability, and test documentation.
WHY LARGER ALUMINUM CONDUCTORS MATTER
Aluminum is widely used in medium-voltage distribution because it is lighter than copper and can offer competitive material cost, particularly for larger conductor sizes. However, it should never be selected by conductor size alone. The final choice must consider resistance, installation environment, insulation temperature, voltage drop, and termination method.
Key checks:
1. Nominal conductor cross-section and construction
2. DC conductor resistance and actual installation ampacity
3. Short-circuit withstand capability
4. Insulation, sheath, and water-protection requirements
5. Compatible lugs, joints, and routine-test reports

DIRECT-BURIAL CABLE: DO NOT COPY AN OLD SPECIFICATION
Underground routes can expose cables to moisture, soil pressure, rocks, excavation damage, and heat accumulation. The installation route should determine the cable structure—not the other way around.
Check point | Why it matters
Water-blocking | Helps limit longitudinal water penetration.
Mechanical protection | Armor or reinforced construction may be necessary.
Outer sheath | Must suit moisture, abrasion, UV, and chemical conditions.
Soil thermal resistivity | Directly affects cable ampacity.

SUPPLY SECURITY IS PART OF TECHNICAL QUALITY
Grid projects can lose time through material shortages, inconsistent production, incomplete test records, or unsuitable packing. That is why procurement teams increasingly evaluate supply reliability alongside product performance.
• Production lead time and capacity plan
• Raw-material and batch traceability
• Inspection and witness-testing options
• Cable drum length, packing proposal, and export documents
• Routine-test reports and third-party-test availability

THE BOTTOM LINE
Modern medium-voltage projects demand more than cable volume. Buyers need a solution that matches electrical performance, route conditions, delivery requirements, and project documentation.
