Malaysia Wire and Cable Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Malaysia Wire and Cable Market Trends and Insights

Data Center and Cloud Infrastructure Expansion

Large data center projects are raising demand for extra-high-voltage underground power cables and fiber backbones in Johor and Selangor. Equinix announced in May 2026 that its KL2 facility in Cyberjaya will involve an investment of more than USD 190 million and will provide more than 2,200 cabinets upon completion.^{[1]Equinix, “Equinix to Develop Purpose-Built IBX Data Center in Kuala Lumpur to Support Malaysia's AI and Cloud Growth,” Equinix Newsroom, newsroom.equinix.com} These facilities need dedicated bulk-power connections rather than standard building wiring. The resulting projects increase demand for products that few domestic suppliers currently manufacture at scale. This procurement pattern also shortens the qualification cycle for local producers who can meet high-voltage standards.

National Grid Modernization and Reliability Investment

TNB's MYR 43 billion grid modernization commitment is increasing the need for medium-voltage, high-voltage, and extra-high-voltage cables. TNB and the State Grid Corporation of China agreed in October 2025 to collaborate on power system planning, resilient network design, and AI-enabled grid management.^{[2]Tenaga Nasional Berhad, “TNB and State Grid Corporation of China Ink MoU to Strengthen Technology Cooperation in Power Grid Modernisation,” Tenaga Nasional Berhad, tnb.com.my} These programs require products that meet tighter technical and reliability requirements than standard distribution cables. Utility procurement, therefore, places greater value on testing records, certified quality, and delivery capacity. The Malaysia wire and cable market benefits from grid expansion and reliability work distribute demand across major transmission corridors.

Renewable Energy Interconnection and Storage Build-Out

Renewable-energy projects need power, control, and signal cables for generation sites, substations, and storage assets. Malaysia's Energy Commission requirements and the planned expansion of grid infrastructure strengthen demand for qualified cable systems. The Sarawak-Sabah interconnection was energized in January 2026, increasing demand for high-voltage transmission equipment across East Malaysia. Cross-border electricity proposals also support interest in submarine and high-voltage transmission systems. Renewable projects create demand across multiple cable types rather than in a single application. This wider procurement base supports the Malaysia wire and cable market as projects move from development to connection work.

Public Transport, Industrial Parks, and Building Electrification

Electric-vehicle charging, industrial parks, and building automation add to demand for low-voltage, control, and structured-cabling products. The Energy Commission issued electric-vehicle charging guidelines in February 2025, and the Ministry of Works published a related guideline in May 2026.^{[3]Malaysian National News Agency, “Works Ministry Launches EV Charging System Guidelines Book,” Bernama, bernama.com} The guidelines specify dedicated cable circuits for charging installations and reinforce the importance of compliant design. Industrial and digital tenants in Johor need medium-voltage supply, fiber networks, and internal control wiring. These projects help maintain demand for established cable categories when large utility projects are delayed.

Copper, Aluminum, and Polymer Input Price Volatility

Copper, aluminum, and polymer costs remain important risks because they account for a large share of cable production costs. Polymer pricing is particularly difficult for suppliers operating under long-term fixed-price agreements. Commodity-linked purchase orders can reduce exposure for larger manufacturers, while smaller low-voltage suppliers have less protection. Cost changes can therefore narrow margins even when order volumes remain healthy. The Malaysia wire and cable market may see greater preference for contracts that allow raw-material price adjustments.

Construction Cycle and Project-Approval Exposure

Demand for low-voltage cable remains closely tied to residential, commercial, and industrial construction activity. Delays in approvals or slower property development can delay procurement for several quarters. Data center proposals also face closer scrutiny of site resources and sustainability requirements. A delayed project can create revenue gaps for suppliers working on project-specific orders. A balanced customer mix across utilities, construction, and industrial users reduces this exposure.

Segment Analysis

By Voltage: Extra-High-Voltage Demand Raises Technical Requirements

Low-voltage cables held 41.23% of the Malaysia wire and cable market share in 2025, supported by demand from homes, commercial buildings, and industrial facilities. This category remains the largest-volume application because these projects need extensive internal wiring and distribution networks. Competition in this tier is more fragmented, and material costs can put pressure on pricing. Medium-voltage products serve industrial parks, renewable-energy substations, and commercial developments. These applications provide a stable demand between major transmission projects.

Extra- and high-voltage cables are expected to grow at a 6.12% CAGR from 2026 to 2031. Grid investment and large data center connections require products with higher technical specifications. TNB's cooperation with the State Grid Corporation of China includes resilient network design and power system planning, which support the need for advanced transmission equipment. SIRIM testing and Energy Commission requirements raise the qualification threshold for grid-connected products. Southern Cable Group is adding medium- and extra-high-voltage production lines, targeting full operation in 2027, demonstrating how domestic suppliers are addressing this capability gap.

By Cable Type: Fiber-Optic Systems Grow Faster Than Power Cables

Power cables accounted for 38.98% of the Malaysia wire and cable market share in 2025. Utility distribution work, renewable-energy connections, and building construction continue to support this large category. Power-cable demand is expected to grow in value as grid upgrades and connection projects proceed. The category also benefits from steady replacement requirements within existing electricity networks. Its broad use across end users gives suppliers a relatively diverse order base.

Fiber-optic cables are projected to grow at a 7.03% CAGR through 2031. Data center construction requires high-capacity fiber systems between facilities and across internal networks. Telekom Malaysia joined the CANDLE submarine cable consortium in September 2025 to develop an 8,000 km system linking Malaysia with several Asian markets and scheduled for operations in 2028. Signal and control cables also benefit from industrial automation, smart-building systems, and charging infrastructure. Telecommunications installations must meet relevant type-approval and IEC requirements, which channels demand toward compliant products.

By Conductor Material: Aluminum Gains Ground Against Copper

Copper held 39.50% of the Malaysia wire and cable market share in 2025. It remains important in building wiring, data cables, and telecommunications applications where conductivity and established specifications matter. Copper-based products also support the low-voltage market, which continues to serve homes and commercial properties. However, higher copper prices encourage engineering and procurement teams to examine material alternatives in large projects. This shift is most relevant where conductor size and total material costs are substantial.

Aluminum is expected to grow at a 6.76% CAGR between 2026 and 2031. It is increasingly used in medium- and high-voltage overhead and underground transmission systems due to its lower weight and relative material cost advantage. Southern Cable Group commissioned a high-capacity aluminum furnace in early 2026, increasing annual aluminum rod output to more than 60,000 metric tons. Optical glass and polymer materials remain smaller by volume but are necessary for fiber systems. Cable producers without aluminum capability may lose some utility project volumes as specifications change at the start of major projects.

By Installation: Submarine Projects Create a Specialized Supply Tier

Underground systems held 40.14% of the Malaysia wire and cable market share in 2025. Urban development, safety rules, and the need for a reliable power supply at data centers support this installation method. Underground systems are particularly important in dense commercial locations where overhead lines are less suitable. Overhead networks remain relevant in rural extensions and long-distance corridors because they can be installed more quickly. Their use is likely to remain important outside high-density urban areas.

Submarine cables are projected to grow at a 7.15% CAGR through 2031. The Sarawak-Sabah interconnection and planned regional projects support demand for power links in East Malaysia. The SALAM initiative was proposed as a 5,582 km domestic submarine system connecting Peninsular Malaysia with Sabah and Sarawak through 10 landing stations. Submarine work requires high technical and marine installation expertise. This creates a supply tier in which global manufacturers with specialized references have a stronger position.

By End-User Vertical: Data Centers Change Digital Cable Demand

Power infrastructure, including utilities and renewables, accounted for 26.89% of the Malaysia wire and cable market share in 2025. Grid upgrades, distribution work, and large-scale generation projects sustain procurement across power cable categories. This end-user group also needs control and signal cables for substations and storage systems. The range of utility applications gives the category a major role in domestic demand. Tighter product qualification requirements can favor manufacturers with strong technical records.

Telecommunications and data centers are projected to grow at a 7.11% CAGR through 2031. Equinix stated that KL2 will support the country's AI and cloud growth through a purpose-built facility in Cyberjaya. These projects require an extra-high-voltage supply, fiber backbones, and control networks, rather than just standard telecommunications cabling. Residential construction continues to provide a stable base for low-voltage wiring. Oil, gas, petrochemicals, mobility, and industrial manufacturing broaden the customer base with specialized and automation-related requirements.

By Insulation: XLPE Becomes the Higher-Value Technical Standard

Insulated cables held 78.98% of the Malaysia wire and cable market share in 2025 and are projected to grow at a 6.89% CAGR through 2031. They are specified across utility, data center, commercial, and residential work. The large share reflects the broad need for safe, durable cable systems across most applications. Non-insulated products remain relevant for overhead transmission and bare aluminum conductors. Their use is more limited in dense urban corridors that prefer underground networks.

Cross-linked polyethylene (XLPE) is replacing polyvinyl chloride in higher-voltage and data center applications. XLPE products have higher unit costs and are suitable for more demanding operating conditions. Cable testing procedures published through the Energy Commission framework reinforce the importance of qualified products for relevant projects.^{[4]Energy Commission Malaysia, “Procedure for Cable Testing,” Energy Commission Malaysia, st.gov.my} Investment in XLPE extrusion equipment creates a barrier to entry for suppliers focused only on standard PVC products. This difference can lead to more defensible pricing for manufacturers serving utility-grade applications.
