India’s data centre build-out has quickly moved from a niche infrastructure theme to a structural investment story. Names like Anant Raj and Netweb have already captured investor attention, becoming early beneficiaries of this shift. Other data center names, such as E2E Networks, Blackbox, and Orient Technology, have also gained significant traction. Yet focusing only on the most visible winners risks missing a deeper layer of opportunity quietly taking shape across the electrical supply chain.

Behind every hyperscale facility, cloud expansion, or colocation project lies a web of power infrastructure, where wires and cables form the backbone. This is where the Indian wires and cables industry steps into focus. Valued at roughly ₹90,000 crore in FY25 (per Polycab), the sector has delivered around 12% YoY growth in FY25, even before the data centre cycle has fully played out. This is when the big demand from Adani, Airtel, and Reliance is yet to come.

That said, the Wire and Cable sector, which accounts for nearly 40%-45% of India’s electrical industry, is now a core enabler of India’s infrastructure and digital ambitions. As data centres scale up, rising power density, tighter redundancy norms, and more stringent safety standards significantly increase their reliance on specialised, high-quality cabling systems.

Here is how these three proxy plays are positioning themselves…

#1 R R Kabel: Plans to Grow Domestic Business by 1.6X

R R Kabel is a key player in the Indian consumer electrical industry. The company manufactures a wide range of electrical products, with a primary focus on wires and cables, and is also expanding its presence in the fast-moving electrical goods (FMEG) segment.

The Engine: Why Wires Are 88% of the Bet

Wires and Cables are the cornerstone of the business, contributing 88% of total revenue in FY25. RR Kabel is the fourth-largest Wires and Cables player by value in FY25. It exports W&C to 74 countries and holds over 42 international product certifications. FMEG business contributes the remaining 12% of revenue.

RR Kabel states that investments in data centers are a driver of demand for wires and cables. The domestic Wires and Cables business is poised to grow by 1.6x, supported by strong external demand factors, including increased investments in emerging sectors such as data centers and renewable energy, as well as industrial capex.

To capitalize on the growing demand, it aims to expand its presence in the data center and original equipment manufacturer (OEM) businesses, where the demand for specialized cables is high. RR Kabel offers a range of specialized cable products for data centers, including aluminum and copper flexible cables, fire-survival cables, battery cables, and low-tension power cables.

Project RRise: A ₹1,200 Crore Capex Gamble

For RR Kabel, scaling the cable business is a strategic focus under “Project RRise,” with a total capital expenditure of ₹1,200 crores planned for FY26-28. This will increase manufacturing capacity (at 90% utilization) by about 1.7x. Approximately 80% of this capacity is dedicated to expanding the cable business.

This includes adding roughly 36,000 Metric tons (MT) of cable capacity at Waghodia and 6,000 MT of wire capacity at Silvassa. The expansion plans aim to achieve production capabilities of up to 220 kV in power cables, enhancing the company’s capabilities in higher-voltage segments.

RR Kabel’s ultimate goal is to achieve an 18% CAGR in wires and cables revenue, along with similar volume growth. It plans to increase its domestic business by 1.6x and its export business by 1.8x. EBITDA margin is also expected to expand by 100 basis points (bps) each year, reaching 10.5% by FY28. EBITDA means earnings before interest, tax, depreciation, and amortisation.

#2 Polycab India: Aims to Outpace Industry Growth Rate

Polycab India is the largest company by revenue and the most profitable company in the Indian electronics ecosystem. The company manufactures and sells wires and cables, and holds a 26-27% market share in the organized wires and cables industry. Polycab is also present in the FMEG business, which includes products such as fans, LED lighting, luminaires, and switchgear.

Wires and cables drive core growth

In addition, Polycab also operates in Engineering, Procurement, and Construction (EPC). This division specializes in turnkey contracting and promotes the use of Polycab-made Extra High Voltage, Medium Voltage, and Low Voltage cables for power projects. In the revenue mix, Wires and Cables accounted for 84% of sales in FY25, followed by EPC (9%) and FMEG (7%).

The AI Catalyst: From Real Estate to Cloud

Polycab expects strong growth across all its business segments. The wires and cables business, Polycab’s core segment, is expected to grow at about 1.5x the industry rate. This growth is supported by government programs such as metro rail, smart cities, and power projects, as well as by the real estate and emerging sectors, such as data centers.
