North America Low Smoke Zero Halogen (LSZH) Cables Market Trends and Insights

Hyperscale and AI Data Center Buildouts

Global AI data center capital expenditure is projected at USD 450 billion in 2026, with North American projects concentrated in Northern Virginia, Texas, Arizona, and Georgia. These projects require more power and data cabling in enclosed technical spaces than conventional server facilities. NFPA 75 Chapter 6 requires cables in IT equipment spaces to limit smoke and toxic gas hazards, while ANSI/BICSI 002 recommends LSZH products for intra-building power and data cabling in data centers. The North America LSZH cables market, therefore, gains from specifications that make fire performance part of the base design for new facilities. This demand favors manufacturers that can provide certified products, reliable deliveries, and documentation for large projects. It also allows cable suppliers to sell coordinated power, fiber, and structured cabling systems rather than isolated products, because campus operators need compatible cables across electrical distribution, equipment rooms, backbone networks, horizontal connections, and enclosed spaces where maintenance teams work. This coordinated approach also simplifies technical review and procurement for complex facilities.

Tightening Fire and Life-Safety Requirements in Enclosed Infrastructure

The 2026 National Electrical Code moved communications circuits from Chapter 8 into Chapter 7, placing them closer to the general wiring requirements in Chapters 1 through 4. This change strengthens the relationship between low-voltage communications work and broader electrical compliance. NFPA 130 requires low-smoke, halogen-free materials in passenger rail coaches, stations, and tunnels, while NFPA 502 applies similar requirements to life-safety systems in road tunnels and bridges. NEC Article 770 and NFPA 262 also influence cable selection in plenum spaces and vertical runs, particularly in large commercial and data center projects. The North America LSZH cables market benefits as owners include LSZH requirements in procurement documents, even when a single code does not explicitly require them. At the same time, the need to maintain qualification records can slow the introduction of revised compound formulations, particularly when a manufacturer must demonstrate consistent performance across flame, smoke, halogen, electrical, and installation requirements. The resulting review process also affects product availability during periods of changing construction and inspection practices.

Premium Pricing Versus PVC-Based Cables

LSZH cables carry a 20-30% price premium over comparable PVC-based products because specialty halogen-free polyolefin compounds cost more than standard PVC compounds. This difference is most significant in residential construction and light commercial retrofit work, where buyers focus on initial material cost. Cable makers with captive compounding operations can reduce their exposure to purchased compound prices and compete more effectively. The cost calculation changes when a project is designed for a stricter code environment from the beginning. Installing compliant products during construction is less disruptive than replacing cables after a facility is complete. The restraint is therefore strongest where building-wire buyers compare LSZH products directly with standard THHN and THWN-2 alternatives, particularly when designs involve modest cable volumes, limited fire-risk assessment, and little scope to recover the initial material premium through a wider project budget.

Other drivers and restraints analyzed in the detailed report include:

• Renewable Power and Battery Storage Expansion
• Industrial Automation and Reshoring of Advanced Manufacturing
• Complex Qualification, Testing, and Certification Requirements

Segment Analysis

Power cables accounted for 31.40% of the North America low-smoke zero-halogen (LSZH) cables market share in 2025, supported by commercial construction, utility upgrades, and renewable power collection systems. Larger building and substation projects use substantial amounts of cable, and tighter smoke-control requirements are encouraging LSZH specifications in their designs. Control and instrumentation products support automated industrial systems, while data and communication cables benefit from enterprise IT upgrades and 5G backhaul work. Building wire remains linked to commercial construction activity, and specialty fire-circuit and transit products serve uses that require performance beyond standard LSZH grades. These demand sources provide the cable-type mix with a broad base across construction, utilities, transport, and digital infrastructure.

Fiber-optic cables are projected to grow at a 9.60% CAGR through 2031, making them the fastest-growing cable type. Hyperscale facilities are increasing the need for dense, fire-safe data infrastructure and for products supported by complete technical documentation. Suppliers with domestic LSZH-rated fiber capacity can respond more quickly to project schedules and qualification requirements. Pre-terminated and structured fiber systems also help installers manage dense connections in large facilities. Fiber, therefore, becomes a more important part of regional demand as operators expand digital infrastructure.

Less-than-1-kV low-voltage products accounted for 68.40% of the North America low-smoke zero-halogen (LSZH) cables market in 2025. Commercial building wiring, IT power distribution, and structured cabling account for much of this volume. NEC, NFPA, and BICSI requirements increasingly shape selection toward low-smoke constructions. Above-65-kV products serve enclosed transmission projects, while the 36-65 kV range is gaining relevance at substations supporting large data center campuses. Both higher-voltage categories serve settings where confined cable corridors and enclosed switch rooms make fire performance especially important.

The 1-35 kV medium-voltage segment is projected to grow at an 8.70% CAGR through 2031. Renewable generation, battery storage, and large data center utility feeds are driving increased demand for medium-voltage products. XLPE-insulated LSZH designs are preferred where high-current operation requires sound thermal performance. Prysmian began a USD 500 million investment in a 650,000-square-foot medium-voltage production facility at its Encore Wire campus in McKinney, Texas, in June 2025, and the facility is expected to come online in 2027. UL-listed XLPE and LSZH constructions are becoming a contractual baseline for major utility and data center projects.
