The Italian Legnano-based company expands its production capacity by regenerating historic industrial sites and strengthening its global growth strategy.
In Legnano, at the heart of Italy’s industrial Lombardy, there’s a story of transformation – in the most literal sense.
Not only because LTC Group manufactures magnetic cores for electrical transformers, but because in recent years it has been transforming itself: from a family-owned business deeply rooted in its territory into a global group, growing in Dubai, Taiwan, and Canada while continuing to invest in its hometown.
In October, LTC completed the acquisition of two historic plants formerly owned by Franco Tosi Meccanica, a true symbol of Legnano’s mechanical tradition.
Two sites, two pieces of industrial history: the first with 15,000 square meters of covered space, the second with another 15,000 and an adjoining 45,000-square-meter lot.
For many, these spaces represented the past — an industrial heritage standing still for decades.
For LTC, they represent the future: an opportunity to keep growing and meet increasing market demand in a sector that is becoming ever more strategic and competitive.
“To follow our customers’ growth, we must grow as well,” say representatives from LTC.
The new spaces will serve multiple needs: from raw material storage to the installation of new cutting machines for electrical steel, as well as to optimize production flows.
And in an area like Legnano, where industrial space is scarce, every opportunity counts.
There’s also a sustainability element behind this decision: instead of building from scratch, LTC chose to revitalize existing facilities, already equipped with high-capacity overhead cranes, thus reducing environmental impact and construction time.
The investments will be significant, but they align with a clear strategy — to grow while strengthening local roots.
A global strategy that starts at home
In the transformer industry, production capacity is now a key factor for competitiveness.
Major international energy players — utilities, renewable operators, and infrastructure developers — are racing to meet the growing demand for new plants and more efficient grids.
It’s a fast-moving market where supply continuity, quality, and delivery speed have become strategic advantages.
The two new plants in Legnano will serve exactly this purpose: to enhance LTC’s overall capacity, integrating seamlessly with existing operations in Italy and abroad.
It’s not just about more space — it’s about building a platform for the next phase of global growth.
Today, LTC employs over one thousand people across four global sites, with direct presence in Europe, the Middle East, Asia, and North America.
Its vision is to create an integrated industrial system capable of delivering reliable supply, consistent lead times, and uniform quality standards across every continent.
“These new facilities will increase our global capacity and allow us to keep investing in more efficient processes,” the company explains.
This move complements LTC’s ongoing greenfield projects — it does not replace them.
The goal is to add, not relocate.

The continuity of a family legacy
Within LTC, multiple generations coexist.
It’s a company that keeps evolving without losing sight of its roots — those planted by Michele Bertelli, who in 1957 founded what would become one of the benchmark companies in the transformer industry. Since then, the group has weathered decades of technological and market change, without ever losing its hallmark ability to innovate while staying true to its identity.
Today, the second generation — Daniele, Aurelio, and Gianluigi Bertelli — leads the company with a solid, international vision, and a strong belief in empowering young people.
It’s a cultural choice as much as a managerial one: at LTC, the average age is 33, thanks also to ongoing collaborations with universities and technical schools, which fuel a steady flow of skills and new ideas.
Among the faces of the third generation, Benedetta and Cristiano Michele Bertelli play central roles, each with over ten years of experience in the group and executive positions within the companies.
Together with Riccardo, Martina, Maria Sole and Federico, they bring fresh perspectives on internationalization, technological innovation, and engagement with new markets.

They embody a generation that blends freshness with continuity, representing the future of the family business.
Yet within LTC, “third generation” doesn’t refer only to the Bertelli family.
It’s also a way of describing the younger people throughout the group, in Italy and worldwide — individuals who share an open, hands-on, and collaborative industrial culture. They are living proof that a company founded over sixty years ago can keep renewing itself — and stay young.
Energy at work
LTC’s motto is simple yet powerful: “Energy at work.”
But behind those three words lies an entire philosophy: just like energy, LTC is in constant motion.
As the world invests massively in green infrastructure, power lines, and data centers, the Legnano-based company is ready to respond — consolidating its role as a global player and industry leader.

Its strength lies in its ability to combine Italian manufacturing excellence with international innovation.
Every new plant, every new project — whether in Italy, Canada, Dubai, or Taiwan — is part of a coherent plan: to bring energy, in every sense of the word, inside and beyond its factories. Ultimately, the principle that guided Michele Bertelli in 1957 is the same that drives his successors today: creating value through work, ingenuity, and trust in the future.
And it’s this energy — the energy of people — that keeps LTC moving forward.
