India's Data Center Boom Fuels Wires and Cables Sector
India's infrastructure landscape is undergoing a rapid transformation, with the data center build-out evolving into a fundamental investment story. While companies directly involved in data centers have garnered attention, a deeper layer of opportunity is quietly emerging within the electrical supply chain. The wires and cables industry, a critical enabler of digital ambitions, is poised for significant growth as data centers scale up.
The wires and cables sector, a core part of India's electrical industry, is valued at ₹90,000 crore for FY25, showing robust year-on-year growth. This occurs before the full impact of demand from major players like Adani, Airtel, and Reliance is realized. High power density and stringent norms in data centers necessitate specialized, high-quality cabling systems, placing this industry at the heart of digital transformation.
RR Kabel's Strategic Expansion Plans
RR Kabel, a key player in Indian consumer electricals, focuses on wires and cables, making up 88% of revenue. As the fourth-largest player, it exports globally. Data centers are a key demand driver. RR Kabel targets 1.6x growth in its domestic Wires and Cables business, expanding into data center and OEM markets with specialized products. Its 'Project RRise' includes ₹1,200 crores capex for FY26-28 to boost capacity by 1.7 times, primarily for cables, aiming for 220 kV capabilities. The company targets an 18% CAGR in revenue and 100 bps annual EBITDA margin expansion.
Polycab India: Leading Growth in the Sector
Polycab India is the largest revenue player in India's electronics ecosystem, dominating the organized wires and cables market. Its business also includes FMEG and EPC. Wires and Cables represent 84% of FY25 sales. Polycab expects its core segment to grow 1.5 times the industry rate, driven by government projects, real estate, and data centers. It highlights AI and cloud computing fueling data center market growth, projected at US$49 billion by 2030. Polycab is supplying cables for these projects and plans ₹6,000-8,000 crore capex over five years. H1 FY26 saw a 21% revenue rise to ₹12,383 crore.
Finolex Cables: Capacity Expansion and Integration
Finolex Cables holds a 23.9% market share in organized wires and is a leader in electrical and telecom cables, with FMEG presence. It offers diverse cables including OFC and data cables. An e-beam facility produces specialized cables for solar, EVs, and railways. Data centers are driving multi-cable demand, including OFC, data, and power cables. Finolex's backward integration in raw materials ensures quality and efficiency. A new OFC preform facility aims for self-reliance, reducing import dependence and boosting margins. Capacity expansion for fiber drawing is also underway. H1 FY26 revenue grew 9% to ₹2,772 crore.
Valuation and Outlook
Polycab leads in return ratios like RoCE and RoE, commanding a premium valuation. RR Kabel trades at a premium but below its median multiple, while Finolex Cables is priced near industry valuation, below its own median post-correction.
India's data center expansion offers a long-term growth runway for wires and cables players. RR Kabel, Polycab, and Finolex Cables provide differentiated exposure through capacity expansion, scale, and integration, offering structurally aligned compounding opportunities for investors.
Impact
This trend is expected to drive substantial growth for companies involved in the electrical supply chain, particularly those manufacturing wires and cables. It signifies a shift towards advanced manufacturing capabilities and a direct link to India's digital transformation goals. The increased demand for specialized, high-quality products will likely lead to improved revenue, profitability, and market positioning for these companies. Investors can view these firms as proxy plays on the burgeoning data center sector.
