In 1926, Maurice Trêve filed the patent for his very first section insulator. At that time, our company did not yet exist; it would be founded in 1948, but already the foundations of recognized expertise had been laid.
A century later, this heritage continues to inspire our development. We have successfully evolved our range of section insulators to support the transformations of railway networks and meet ever-increasing demands for performance and reliability.
Our expertise has been forged through interaction with technological developments and the diverse needs of networks. This variety of environments and technical constraints has led us to design section insulators adapted to each context, regardless of the specific challenges encountered.
Today, our solutions cover all voltage levels present on the networks:
- 750 V for trams,
- 1500 V and 3000 V for conventional lines,
- 15 kV and 25 kV for high-speed lines.
This ability to offer solutions tailored to each environment illustrates our ongoing commitment to supporting infrastructure operators and managers.
Since our inception, we have relied on this technical heritage to continue innovating, perfecting our products and meeting the challenges of today's and tomorrow's railway networks.
Celebrating this centenary is above all about valuing a strong industrial history, looking towards the future.
