ABB to Acquire Specialtrasfo to Support Industrial Electrification With Specialized Transformer Offering
May 14, 2026
ABB has signed an agreement to acquire Specialtrasfo S.p.A., a privately-owned Italian manufacturer of specialized medium voltage (MV) transformers, including converter and rectifier transformers, with an installed base spanning over 70 countries worldwide.
Specialized transformers are custom-engineered components supporting critical industrial and energy applications through efficient power conversion, control and reliable system performance. The acquisition enables ABB to offer customers a fully optimized powertrain solution, built to meet the most demanding requirements and allowing ABB to respond to customer needs with speed and agility. The transaction is expected to close in Q3 2026, subject to customary regulatory approvals and the business will be integrated into ABB’s Motion High Power division. Financial terms of the transaction were not disclosed.
Specialtrasfo was founded in 1946, is headquartered in the Milan area (Agrate Brianza) and has three manufacturing sites in northern Italy with a total of 130 employees. In 2025, the company has generated revenues of approximately 80 million euros, with ABB representing around half through its integrated offering. The offering ABB is acquiring focuses on specialized transformers for various industrial applications including energy, marine, metals, mining, industrial processing and offshore applications adding a key building block to its powertrain offering and reinforcing its position as a partner of choice for customers seeking integrated, high-performance solutions.
“ABB and Specialtrasfo’s decades-long commercial relationship is a testament of the trust ABB has in the technical expertise, proven quality and reliability of the transformers they produce,” says Juha Koskela, President of ABB’s Motion High Power division. “This strategic acquisition expands our offering and strengthens our supply chain resilience in high‑demand transformers, reinforcing ABB’s ability to provide reliable, integrated solutions. By combining high‑power motors, drives and transformers in a single, high‑quality portfolio, we continue to help customers meet their specific industry requirements with confidence”.
According to International Energy Agency (IEA), global electricity demand is expected to double by 2050 driven by rising industrial use of electricity and the expansion of data centers and AI. This increase in electricity demand is a key driver for the growing need for transformers, a critical element in industrial power conversion. With this acquisition, ABB complements its capabilities to respond to this growing demand through a vertical integration that enhances supply chain resilience with a key component for the powertrain offering.
