ABB has signed an agreement to acquire Specialtrasfo, an Italian manufacturer of specialized medium-voltage transformers, as part of efforts to expand its industrial electrification portfolio.
The transaction, expected to close in the third quarter of 2026 subject to regulatory approvals, will see the business integrated into ABB’s Motion High Power division. Financial terms have not been disclosed.
Specialtrasfo produces converter and rectifier transformers designed for both motor-driven and non-motor industrial applications. These components are used in sectors including marine, energy, metals, mining, industrial processing and offshore operations.
Founded in 1946 and headquartered in Agrate Brianza, Italy, the company operates three manufacturing sites in northern Italy and employs around 130 people. In 2025, it generated revenues of approximately €80m (US$93m). ABB already accounts for around half of this through an existing commercial relationship.
ABB said the acquisition will allow it to incorporate specialized transformers into its existing motors and drives offering, creating a more integrated powertrain portfolio. The company also expects the move to improve supply chain resilience and responsiveness to customer demand.
“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,” said 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.”
