Industry analysis forecasts more than a doubling of the global cables market over a decade, with government-led connectivity programmes, power grid modernisation, and the rapid rise of internet services creating sustained long-cycle demand across multiple sectors.
The global cables market was valued at $74.72 billion in 2020 and is projected to reach $156.49 billion by 2030, growing at a compound annual growth rate (CAGR) of 7.8%, according to a market analysis published by Allied Market Research. The forecast reflects the foundational importance of cable infrastructure across two of the most significant global trends of the current decade — the transition to clean energy and the expansion of digital connectivity.
Cables are the physical medium through which electricity and data move between generation sources, transmission networks, distribution systems, and end users. As governments and private investors accelerate spending on renewable energy installations, grid upgrades, 5G networks, and broadband rollouts, the cumulative volume of cable required to underpin this infrastructure is growing at a pace that analysts describe as structurally sustained through the end of the decade.

IT and Telecommunications Leads End-Use Demand; Aerospace and Defence Grows Fastest
By end-use vertical, the IT and telecommunications segment generated the largest share of global cables market revenue in 2020, accounting for approximately one-quarter of total market value. The underlying drivers are well established: rising global smartphone penetration, rapid expansion of internet access in developing economies, and the ongoing build-out of broadband and mobile network infrastructure across both urban and rural geographies.
The global rollout of 5G networks is a particularly significant demand driver within this segment. Unlike previous generations of mobile network infrastructure, 5G architecture — especially in its densified small-cell configurations — requires substantially more cabling per unit of geographic coverage than 4G systems. Fibre optic backhaul cables connect each base station to the core network, and as the density of 5G deployments increases in urban areas, the aggregate cable requirements scale proportionally. Data centre expansion, driven by cloud computing adoption, streaming media consumption, and the growth of AI infrastructure, is generating parallel demand for high-density, high-bandwidth internal and interconnect cabling solutions.
The aerospace and defence segment, while smaller in absolute revenue terms, is identified as the fastest-growing end-use vertical, projected to record the highest CAGR of 10.7% from 2021 to 2030. Increasing demand for data security, information integrity, and high-bandwidth communications within military and aerospace platforms is driving investment in specialised, high-performance cable systems that meet the stringent performance, weight, and reliability requirements of defence and aviation applications.
Low Voltage Leads by Market Share; High Voltage Records the Highest Growth Rate
By voltage type, low-voltage cables held the largest market share in 2020, accounting for more than two-fifths of global cables market revenue. Low-voltage cables are ubiquitous across industrial facilities, commercial buildings, residential construction, appliance wiring, and utility distribution networks — applications where the sheer volume of installed cable is driven by the density and diversity of end-use environments rather than by any single large-scale project category.
High-voltage cables, however, are projected to record the fastest growth over the forecast period, with an expected CAGR of 10.9% from 2021 to 2030. The primary driver is the scale of investment in long-distance electricity transmission infrastructure associated with renewable energy integration. Connecting large solar farms, wind power installations, and offshore wind facilities to national grid networks requires high-voltage and extra-high-voltage cable systems capable of transmitting bulk power over distances of hundreds or thousands of kilometres with minimal energy loss.
Cross-border electricity interconnectors — which allow neighbouring countries and regions to balance supply and demand across larger geographic areas and share renewable generation capacity — are an additional source of high-voltage and ultra-high-voltage cable demand, particularly in Europe, where grid interconnection is a stated policy priority under the European Green Deal.
Submarine high-voltage cables represent a specialised and growing sub-segment. Offshore wind farms require submarine cables to bring their output onshore, and inter-island or cross-sea power links in markets including the United Kingdom, the Nordic region, and parts of Asia are generating procurement activity for some of the most technically demanding cable products the industry produces.
Overhead Installation Dominates; Underground and Submarine Segments Expand
By installation type, overhead cables held the dominant position in the global cables market in 2020. Overhead lines remain the lowest-cost method for transmitting electricity across open terrain and continue to be the preferred option for grid expansion in regions where land constraints, environmental regulations, and population density do not necessitate underground alternatives. The economics of overhead installation — lower upfront cost per kilometre relative to underground alternatives — make it the default choice for transmission network expansion in large parts of Asia, Africa, and Latin America.
Underground cable installations are growing in significance, driven by urbanisation, resilience requirements, and aesthetic or environmental constraints that make overhead lines impractical in city environments. In Europe and parts of North America, regulatory pressures and public resistance to overhead transmission lines in populated areas are accelerating the shift toward underground solutions, despite their higher installation cost.
Submarine cable installations, while representing a smaller share of total volume, are among the highest-value deployments in the market and are attracting significant capital investment as offshore wind development and subsea power interconnection accelerate globally.
Asia-Pacific Dominates Globally and Leads in Growth Rate
Geographically, Asia-Pacific held the largest regional share of the cables market in 2020, contributing more than two-fifths of global revenue. The same region is also expected to record the highest CAGR of 9.3% through 2030 — a combination of scale leadership and growth leadership that reflects the breadth and depth of infrastructure investment across the region.
China’s scale is central to Asia-Pacific’s dominance. The country’s sustained investment in ultra-high voltage direct current transmission networks — among the most ambitious electricity infrastructure programmes in the world — generates enormous cable volumes. Simultaneously, China’s expanding 5G rollout, data centre construction, and renewable energy installations each contribute to cable demand across multiple product categories and voltage levels.
India is identified as another high-growth market within the region, driven by the government’s national electrification and rural connectivity programmes, the expansion of renewable energy capacity under national clean energy targets, and rapidly rising consumer demand for internet and mobile services. Indonesia, with its archipelagic geography and growing economy, presents particularly significant opportunities for submarine cable deployments connecting its dispersed island provinces.
Beyond Asia-Pacific, North America and Europe remain substantial markets. The report notes that rising living standards and technological advancements in developing countries across the Asia-Pacific region — including India, China, and Indonesia — are among the factors reinforcing the region’s growth leadership.
Government Connectivity Initiatives and Renewable Energy Policy Create Durable Demand
A recurring theme across the cables market analysis is the role of government policy in creating and sustaining demand. National broadband plans, rural connectivity programmes, renewable energy mandates, and grid modernisation frameworks all translate directly into cable procurement at scale. In markets where government policy is most ambitious and well-funded — the European Union’s Green Deal and Digital Decade agenda, India’s national broadband and solar energy programmes, China’s State Grid investment plans, and the United States’ Infrastructure Investment and Jobs Act — cable demand is expected to remain structurally elevated through the forecast period.
The electrification of transportation is an additional policy-driven demand catalyst. As governments in Europe, North America, and parts of Asia introduce targets and incentives for electric vehicle adoption, the public and private investment in EV charging infrastructure creates demand for low and medium-voltage cables at the distribution and building level, supplementing the high-voltage cable demand generated by transmission grid expansion.
Challenges: Deployment Complexity and Government Authorisation Delays
Despite a positive demand environment, the cables market faces operational challenges that can slow the translation of investment commitments into actual procurement and installation. The planning and deployment of large-scale cable infrastructure — particularly underground and submarine installations — involves significant technical complexity, extended project timelines, and in many cases protracted regulatory approval and government authorisation processes.
Permitting delays for grid infrastructure projects have been documented across multiple major markets. Environmental impact assessments, land access negotiations, and the involvement of multiple regulatory agencies can extend project development timelines by years, deferring cable procurement even when investment funding has been secured. This dynamic is particularly evident in Europe, where ambitious grid expansion and offshore wind connection targets are constrained by permitting processes that were designed for an earlier era of infrastructure development.
Raw material cost volatility — particularly for copper and aluminium, the primary conductive materials in most cable products — presents a persistent challenge for manufacturers and project developers alike. Input cost fluctuations can affect contract pricing, project economics, and supply chain planning in ways that complicate long-term procurement strategies.
Competitive Landscape
The global cables market features a mix of large international manufacturers with diversified product portfolios and regional specialists serving specific geographic or application niches. The market analysis notes the presence of established players competing on the basis of technical capability, manufacturing scale, geographic reach, and supply chain reliability — factors that are increasingly important as large-scale grid and telecommunications infrastructure projects demand assured supply of high-specification cable products delivered to tight project timelines.
Competitive strategies in the sector centre on capacity investment — particularly in high-value segments such as HVDC submarine cables and high-frequency data cables — alongside geographic expansion through acquisitions and partnerships, and the development of specialised product ranges for emerging application areas including offshore wind, EV charging infrastructure, and next-generation data centre connectivity.
Outlook
The cables market’s trajectory through 2030 is shaped by infrastructure investment trends that are among the most capital-intensive and geographically broad in the global economy. The simultaneous expansion of renewable energy capacity, electricity grid modernisation, 5G network rollout, and broadband deployment across both advanced and emerging economies creates a demand environment with multiple, mutually reinforcing growth drivers.
The pace at which the energy transition translates into physical infrastructure investment — and by extension into cable procurement — will be a key determinant of market performance over the forecast period. Analysts point to the scale of policy commitment across major economies, the economic logic of renewable energy at current cost levels, and the growing recognition of grid infrastructure as a binding constraint on clean energy deployment as foundations for sustained above-average growth in the global cables market through 2030 and beyond.
