Data center laminated busbar market set to reach $0.66 billion by 2031

AI infrastructure drives higher power requirements

Rising power consumption per server rack is increasing demand for laminated busbars that can distribute high currents efficiently while using less space. MarketsandMarkets links the market's growth to investment in hyperscale data centers, cloud computing infrastructure and AI-driven computing facilities.

The report says manufacturers are developing busbars with higher current-carrying capacity, improved thermal performance and configurations tailored to high-density server racks. Companies are also focusing on lightweight materials, optimized electrical designs and integration with power distribution units, or PDUs, and uninterruptible power supply, or UPS, systems.

In the market forecast, the segment rated above 3,000 A is projected to record the highest CAGR during the forecast period. Switchgear and power distribution is estimated to be the largest application segment in 2025.

Copper and hyperscale facilities lead key segments

Copper held 74.0% of the overall market in 2025, making it the leading conductor material, according to the report. MarketsandMarkets attributes its position to copper's electrical and thermal conductivity, mechanical strength and established manufacturing and qualification practices.

As rack power rises, copper can help designers carry higher currents in limited space with thinner conductor layers, lower resistive losses and less heat generation. The report also connects copper demand to low-inductance designs, higher-voltage DC architectures and the construction and expansion of data centers. Aluminum and hybrid conductors are gaining attention for cost and weight management, but copper is expected to remain the preferred conductor through the forecast period.

Hyperscale is projected to be the fastest-growing data center type. Large cloud and AI campuses require substantial volumes of power equipment, while higher rack power supports demand for compact, high-current and low-loss distribution. Standardized site designs and open rack specifications can also support repeat orders and modular, prefabricated power systems.

North America is forecast to be the fastest-growing region

North America is projected to register the fastest growth, with a 19.6% CAGR during the forecast period. The report attributes this outlook to AI and hyperscale data center construction across the US and Canada, along with capacity expansions requiring switchgear, power conversion systems, UPS and battery systems, and rack-level power shelves.

MarketsandMarkets identifies higher-voltage DC power architectures, liquid-cooled busbar assemblies, open rack standards and modular, prefabricated power systems as trends shaping regional demand. It also says busbars are increasingly being integrated with capacitors and cooling elements into complete power modules, while aluminum and hybrid conductors are being evaluated to manage copper price exposure.

The report covers market data for 2022 to 2031 and includes 265 tables, 75 figures and 350 pages. Companies listed in the industry include Mersen, Amphenol IPC, Rogers Corporation, Methode Electronics, Inc., SUN.KING Technology Group Limited, A&J Link Technology (Suzhou) Co., Ltd., Permanent Magnets Limited, Dongguan Leixun New Energy Technology Co., Ltd., Zhejiang RHI Electric Co., Ltd. and Storm Power Components.

MarketsandMarkets also identifies 800 VDC power distribution as an emerging technology for next-generation AI data centers. Its adoption is still developing, so the report presents it as a potential source of demand for higher-voltage busbars rather than a mainstream market standard.
