Enhancement of the maintenance organization within electricity transmission networks

Live working

Comprehensive Support for Establishing LW Teams

We have developed an internationally recognized “French method,” tailored to the specific context of each worksite. This approach offers greater flexibility compared to traditional methods based on fixed operating procedures and has demonstrated its effectiveness in ensuring safety, with no fatal accidents recorded in 50 years of LW practice in France.

Equipment and Machinery for LW Substations and Lines

We provide a comprehensive range of equipment for low-, medium-, and high-voltage operations on substations and power lines. Our offerings include LW tools, lifting platforms, insulated scaffolding, and connection/disconnection solutions. These tools, specifically designed for the French LW method, surpass international standards to ensure the utmost safety for operators. Our rigorous tool qualification processes ensure that LW deployments adhere to the highest standards of quality and safety.
