Mineral Insulated Cables Market to See Strong Growth Driven by Safety Regulations and Infrastructure Investments
Mineral insulated cables market expands as fire safety codes, infrastructure upgrades, and energy projects fuel global demand.
NEWARK, DE, UNITED STATES, August 14, 2025 /EINPresswire.com/ -- The global mineral insulated (MI) cables market is projected to grow from USD 1.8 billion in 2025 to USD 3.4 billion by 2035, achieving a CAGR of 6.6%. This growth trajectory is fueled by stricter fire-safety standards, large-scale infrastructure upgrades, and escalating demand from high-temperature and mission-critical applications.
Between 2020 and 2024, adoption was heavily influenced by regulatory mandates in industrial facilities. In 2023, over 41% of new oil & gas processing units in the Middle East incorporated MI wiring for zone-1 and zone-2 classified areas, while installations in UK rail tunnels surged by 12.5% year-on-year due to compliance retrofits. By 2025, over half of global MI cable demand will stem from fire-critical uses across energy, transportation, and heavy manufacturing.
In the broader USD 200 billion industrial cables industry, MI cables represent a niche but essential 2–3%, valued for unmatched fire resistance and longevity. Their share within the USD 10 billion fire-resistant cables market stands at 12–15%, and they hold significant presence in power transmission, oil & gas, and building safety wiring segments.
Key Segment Insights
- Magnesium Oxide (MgO) Insulation – Expected to command 66% market share by 2025, MgO offers non-combustibility, superior thermal stability, and exceptional dielectric strength, making it indispensable in nuclear plants, tunnels, and airports.
- Copper Sheath Material – Forecast to capture 48% market share, copper sheathing is preferred for its conductivity, corrosion resistance, and mechanical flexibility in power distribution and metro projects.
- High-Temperature Range (up to 1000°C) – Set to account for 44% share, these cables are crucial in refractory environments, emergency circuits, and furnace wiring.
- Multi-Core Configurations – Anticipated to hold 32% share, multi-core designs enable efficient installations in airports, refineries, and smart buildings.
- Tunnels – Remaining a high-priority end-use segment at 21% share, driven by metro expansion, safety compliance, and urban infrastructure upgrades.
Market Drivers
Fire-rated infrastructure projects have accelerated MI cable deployment, with installations rising 38% year-on-year. Municipal transport systems in Europe and Asia-Pacific lead adoption, while the oil & gas sector has shifted to corrosion-proof MI variants, improving service life and reducing failures in harsh environments.
Global investments exceeding USD 300 billion in grid modernization and clean energy are further boosting demand. Europe continues to mandate EN 60702-compliant MI cables in critical infrastructure, while India and Southeast Asia show rapid adoption potential in commercial construction.
Regional Highlights
- India – Leads with a projected 7.5% CAGR, driven by metro rail expansion, smart grids, and fire safety upgrades in high-density urban zones.
- China – Growing at 6.8% CAGR, supported by retrofitting programs, metro projects, and strict fire code enforcement.
- Germany – Matches China’s growth rate, with increased use in offshore wind farms, renewable projects, and public transport.
- UK – Expanding at 6.3% CAGR, fueled by healthcare, education, and rail infrastructure upgrades.
- US – Growing at 5.4% CAGR, adoption is supported by energy resilience programs, EV charging infrastructure, and grid-hardening initiatives.
