TET ESTEL, an Estonian electrical engineering company, has contributed to the supply of components for CERN’s Large Hadron Collider (LHC) project.
In 1990, TET ESTEL supplied stabilized current power modules for the LHC.
Later, in 2022, the company delivered eight high-tech converters to power the LHC, ensuring its uninterrupted operation.
In 2025 TET ESTEL started working on a new project that includes the design, manufacture, assembly of 60kV 40A diodes rectifiers for the accelerator complex at CERN, the flagship of which is the Large Hadron Collider.
These collaborations demonstrate TET ESTEL’s expertise in providing reliable, high-quality equipment for complex scientific endeavors. Through its continued work with CERN, TET ESTEL plays a role in supporting cutting-edge research and technological advancements in high-energy physics.
