According to TechSci Research report, “Underground Medium Voltage Cable Market - Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2030F, The Global Underground Medium Voltage Cable Market was valued at USD 11.6 billion in 2024 and is expected to reach USD 15.77 billion by 2030 with a CAGR of 5.1% through 2030. One significant driver is the rising need for improved grid reliability and safety.

Underground MV cables are less susceptible to weather-related disruptions such as storms, floods, or extreme heat, which makes them ideal for regions facing climate change-related challenges. As power outages become costlier and more disruptive, utilities are increasingly investing in underground cable networks to ensure stable and uninterrupted electricity supply.

Another key driver is the expansion of industrial zones and data centers. With industries requiring uninterrupted power for critical operations and data centers needing high-reliability electrical infrastructure, the demand for durable and efficient underground MV cables is growing. Additionally, the global trend toward electrification of transportation—such as electric vehicle charging infrastructure and electrified railways—is adding pressure on power distribution networks, further boosting the need for underground cabling solutions. 

Government regulations and safety mandates are also playing a role. Many countries have introduced stricter standards for power distribution systems, pushing utilities and developers to adopt underground cabling for enhanced safety and compliance. Moreover, advancements in cable design and installation technology are reducing costs, making underground MV cable deployment more feasible at scale.

Based on Product, Cross-Linked Polyethylene (XLPE) Cables segment dominated the Underground Medium Voltage Cable Market in 2024 and maintain its leadership throughout the forecast period, due to its superior performance characteristics, widespread adoption, and compatibility with modern power distribution needs. XLPE cables are particularly favored for their excellent electrical, thermal, and mechanical properties, making them ideal for medium voltage applications ranging typically between 1 kV and 35 kV. Unlike traditional PVC-insulated cables, XLPE cables can operate at higher temperatures, often up to 90°C during normal operations and even higher under short-circuit conditions, without deteriorating in performance. This enables longer cable lifespans and improved reliability, which is crucial for underground installations that are difficult and costly to access once installed.

A key factor contributing to the dominance of XLPE cables is their resistance to environmental stressors such as moisture, chemicals, and abrasion. These features make them particularly well-suited for underground applications, where cables are exposed to harsh soil conditions, water intrusion, and fluctuating weather patterns. In addition, XLPE insulation provides better current carrying capacity and reduced dielectric losses, which translates into greater energy efficiency and cost-effectiveness over time. These benefits have led utility companies, infrastructure developers, and industrial users to increasingly prefer XLPE cables over alternatives like PILC (Paper Insulated Lead Covered) or EPR (Ethylene Propylene Rubber) cables.

Rapid urbanization, expanding infrastructure projects, and the need to upgrade aging electrical grids have further propelled the demand for XLPE underground MV cables. Countries across North America, Europe, and Asia-Pacific are investing heavily in smart grid initiatives, renewable energy integration, and undergrounding of power lines to reduce outages and improve aesthetics in urban settings. These modernization efforts almost universally specify XLPE cables due to their proven performance and compliance with international safety and energy standards.

Additionally, XLPE cables are lightweight and easier to handle compared to other types, which simplifies installation and reduces labor costs—a major advantage in complex urban underground cabling projects. The segment also benefits from ongoing technological advancements, such as the development of water-tree retardant XLPE and thermally upgraded XLPE variants, which further improve their durability and operational efficiency.

Manufacturers like Prysmian Group, Nexans, and NKT have significantly expanded their XLPE cable production capacities to meet rising global demand. Many governments and utilities now mandate or recommend XLPE in public infrastructure projects, reinforcing its market leadership. As the global focus intensifies on energy reliability, environmental sustainability, and operational efficiency, the XLPE segment is expected to maintain its dominance in the underground MV cable market for the foreseeable future.

Asia Pacific is emerging as the fastest-growing region for the Underground Medium Voltage Cable Market, driven by rapid urbanization, industrial expansion, and aggressive infrastructure development across major economies such as China, India, Japan, and Southeast Asian nations. The region is experiencing a massive transformation in its energy infrastructure, with governments investing heavily in upgrading aging transmission and distribution networks to support growing electricity demand and reduce power losses. This shift is particularly evident in urban areas, where underground cabling is increasingly preferred over overhead lines for safety, reliability, and aesthetic reasons.

China, for instance, has committed to massive grid modernization under its 14th Five-Year Plan, allocating billions of dollars to improve power infrastructure. India, on the other hand, is targeting 500 GW of renewable energy capacity by 2030, which necessitates substantial investment in efficient, medium voltage cable networks for both urban and rural electrification. The growth of smart cities and industrial corridors further fuels demand for reliable and durable underground MV cables.

Moreover, favorable government policies, foreign direct investments, and public-private partnerships are enabling large-scale deployment of MV cable systems. Asia Pacific also benefits from the presence of major cable manufacturers and a strong supply chain, ensuring competitive pricing and timely delivery. The region’s growing emphasis on renewable energy integration, grid resilience, and reduced transmission losses continues to accelerate underground cabling projects. As a result, Asia Pacific is poised to lead global growth in the underground MV cable market in the coming years.
