Data Center Power Cable Market to Reach USD 4.72 Billion by 2035 as AI Campuses Pull Medium-Voltage Distribution Deeper Into the Data Hall - DC Market Insights
Market grows at a 10.50% CAGR from USD 1.74 billion in 2025; low-voltage power cables hold 40.4% of spending, DC power cables grow fastest at 11.55% a year and North America leads with 42.0%
LONDON, /PRNewswire/ -- The 'Data Center Power Cable Market - Growth, Share, Opportunities & Competitive Analysis, 2026-2035' report has been added to the DC Market Insights offering. The global Data Center Power Cable Market was valued at USD 1.74 billion in 2025, is estimated at USD 2.26 billion in 2026, and is projected to reach USD 4.72 billion by 2035, growing at a CAGR of 10.50% from 2025 to 2035. DC Market Insights finds that AI campuses are changing electrical architecture by taking 15 kV to 35 kV feeders closer to the load, while copper prices, higher rack density and re-cabling of older halls lift the value of each megawatt deployed.

"Data center power cable demand is being reshaped by both AI architecture and metal economics. AI halls use about USD 145,000 of power cable per MW at 2025 copper prices, while medium-voltage feeders move closer to the load and older facilities need heavier re-cabling for denser racks. That makes copper exposure, MV capacity and conductor substitution as important to procurement strategy as the number of megawatts under construction."

Why This Report Matters
Power cables connect the campus substation, switchgear, UPS, mechanical plant and rack-level distribution, so their economics move with both megawatts and metal prices. The report helps cable manufacturers, distributors, electrical contractors, data center developers, hyperscalers, colocation operators and investors quantify product mix, copper and aluminium exposure, new-build versus re-cabling demand and the regions where AI campus construction is pulling medium-voltage distribution deeper into facilities.

How Big Is the Data Center Power Cable Market in 2026?
DC Market Insights values the Data Center Power Cable Market at USD 2.26 billion in 2026, 30.08% above 2025. The increase reflects higher copper prices, rapid AI campus construction and more medium-voltage distribution inside large sites. Growth moderates after the 2026 price reset but remains supported by annual capacity additions and re-cabling of the expanding installed base.

Why Do AI Campuses Increase Power Cable Content per MW?
Power cable content averaged about USD 115,000 per new MW of air-cooled IT capacity and USD 145,000 per MW in an AI hall in 2025. AI campuses move 15 kV to 35 kV feeders closer to unit substations near the hall, add large mechanical loads and use denser rack-level distribution. Copper prices amplify the effect: roughly 55% of an AI hall cable bill is copper metal, so each USD 1,000 per tonne change in copper adds about USD 8,000 per MW to cable cost.
Which Power Cable Type Leads Data Center Spending?
Low voltage power cables remain the largest product type, while medium-voltage feeders capture a larger absolute revenue pool as AI campuses bring MV distribution closer to the load. DC power cables grow fastest from a smaller base as battery strings and rack-level DC architectures expand.
