The denmark wire and cable market size is projected to expand from USD 660.22 million in 2025 and USD 675.47 million in 2026 to USD 757.18 million by 2031, registering a CAGR of 2.31% from 2026 to 2031. This report is Segmented by Voltage (Extra- and High-Voltage (Greater Than 35 KV), and More), Cable Type (Power Cable, and More), Conductor Material (Copper, Aluminum, and More), Installation (Overhead, Underground, and Submarine), End-User Vertical (Residential Construction, and More), and Insulation (Insulated, and Non-Insulated). The Market Forecasts are Provided in Terms of Value (USD).
Extra- and high-voltage cables are projected to grow at a 3.26% CAGR through 2031. NKT reported a Transmission order backlog of EUR 13.5 billion (USD 15.39 billion) at the end of the first quarter of 2026. Denmark’s undergrounding program has developed experienced contractors and high-voltage engineering capacity. This experience is being applied to HVDC links, offshore connections, and large grid reinforcement work, where design, jointing, testing, and installation must meet demanding utility requirements. IEC 60228 and IEC 62067 remain important technical standards for conductor classification and the qualification of high-voltage extruded cables.
Power cables accounted for 69.42% of the Denmark wire and cable market size in 2025. They are also projected to grow at a 2.98% CAGR through 2031. Energinet’s completed projects in 2025 used hundreds of kilometers of underground power cable. Grid reinforcement needs power cables in transmission corridors, local distribution systems, substations, wind farm collector networks, and the connections that link these assets. This makes power infrastructure the primary source of cable volume.
Fiber-optic cable is an important secondary category due to the copper network phase-out and the emergence of new subsea systems. TDC Net reported 23% growth in fiber revenue in 2025. Signal and control cables remain in demand for offshore platforms, industrial automation, and data centers. Coaxial and data cables face lower residential volumes as copper broadband is retired. Prysmian’s July 2026 agreement with Molex, valued at up to EUR 5.5 billion (USD 6.27 billion), suggests that global optical cable capacity may become tighter as data center demand rises.
Denmark Wire and Cable Market Trends and Insights
Offshore Wind and Energy-Island Cable Buildout
Offshore wind development is the strongest demand driver for extra- and high-voltage cables through the late 2030s. The Bornholm Energy Island project aggregates up to 3.8 GW of Baltic Sea offshore wind and requires a connection to Zealand. Energinet awarded NKT A/S a EUR 650 million (USD 700 million) contract on September 3, 2025, for 525 kV HVDC cable systems covering 200 km offshore and 16.8 km onshore, with commissioning expected in 2032. Germany and Denmark signed a joint development agreement in January 2026, supported by a EUR 645 million (USD 735 million) Connecting Europe Facility grant. The agreement positions the project as a model for offshore interconnectors. NKT Eleonora is expected to become operational in 2027, and vessel availability will influence project schedules alongside manufacturing capacity.Transmission-Grid Reinforcement and Undergrounding
Energinet’s 184 active electricity grid projects support medium- and high-voltage cable demand through 2031. The completed 172 km West Coast Connection and the 21 km 150 kV Herning-Videbæk underground section reflect the conversion of overhead lines to XLPE cable systems. The Environmental Assessment Act reform, effective January 1, 2026, lets Energinet conduct in-house screening for qualifying projects. The company had applied the process to 28 projects by the first quarter of 2026. The reform could shorten commissioning timelines by 6 to 12 months. Approval backlogs will still affect the timing of cable orders, especially before projects reach procurement.Copper and Aluminum Price Volatility
Copper reached USD 13,544 per tonne on the London Metal Exchange in May 2026, changing procurement economics for cable buyers. The copper-to-aluminum price ratio reached 4.3 in January 2026 and remained near 4.2 through mid-2026. This ratio is above the 3.5-4.0 range, which can prompt procurement teams to review aluminum substitution. Copper accounts for 70% to 85% of the production cost of copper-conductor cable. Sustained price increases can compress distributor margins and place pressure on multiyear supply agreements. Quarterly adjustments under LME-linked pricing also make long-term budgeting more difficult for distribution operators, developers, and offshore wind contractors.Other drivers and restraints analyzed in the detailed report include:
- Fiber-Optic Network Expansion and Copper-Network Phase-Out
- Electrification of Transport, Buildings, and Industry
- Long Environmental Approval and Grid-Connection Timelines
Segment Analysis
Low-voltage cables held 43.68% of the Denmark wire and cable market share in 2025. Residential wiring, EV charging conduit, and distribution-level industrial connections support this volume. These uses create broad demand across new buildings, renovation, and local distribution work. Medium-voltage cables serve distribution substations, industrial parks, and wind farm collector systems. NKT completed an Asnaes capacity upgrade in June 2026, strengthening its ability to supply this tier.Extra- and high-voltage cables are projected to grow at a 3.26% CAGR through 2031.
