Experience in manufacturing welded components for high-voltage power transformers
We specialize in the development and global distribution of transformer tanks.
With expanded manufacturing capabilities, our goal is to meet increasing market demands and strengthen our position as a key supplier on the international stage.
With decades of experience, we bring together heritage and innovation. The formation of an independent transformer tank division marks a bold step forward – enhancing agility, accelerating innovation, and meeting the evolving demands of a global energy sector. This strategic shift empowers us to lead with greater precision, invest in smarter production, and deliver even higher standards of performance and reliability.
Transformer tanks
We manufacture custom transformer tanks for large-scale power transformers (LPT), tailored for offshore environments, low-temperature conditions (< –40 °C), HVDC systems, phase-shifting units, and other specialized uses.
Alongside structural steel, we also utilize stainless steel, aluminum, and copper in select applications. Our manufacturing facility – equipped with 12-meter-high ceilings and dual cranes (2 × 63 t) – enables the fabrication of transformer tanks exceeding 100 tons.
Our solutions are trusted by global leaders in the electrical industry, with exports spanning Germany, Austria, France, the Netherlands, Belgium, Slovenia, the United States, South Korea, and more.
