Increased global electricity demand is a key driver for the growing need for specialized transformers
Acquisition strengthens ABB’s integrated powertrain portfolio that is supporting the rapid electrification of industries
Combined expertise broadens the offering to new and existing customers across multiple applications
ABB announces the completion of its acquisition of Specialtrasfo S.p.A., an Italy-based manufacturer of specialized medium voltage transformers, including converter and rectifier transformers. The acquisition includes three production sites in Italy and over 130 employees. In 2025, the company generated revenues of approximately 80 million euros, with ABB representing around half through its integrated offering. The transaction was announced on May 12, 2026, and financial terms were not disclosed.
The increase in global electricity demand is a key driver for the growing need for transformers, a critical component in industrial power conversion. By acquiring Specialtrasfo, ABB strengthens its extensive portfolio with converter and rectifier transformers, whilst Specialtrasfo will continue to serve its existing customers as a transformer supplier. This increases supply chain resilience to meet customer needs across a wide variety of industries including energy, metals, mining, industrial processing and offshore applications.
