Traction Power Systems for advanced rail electrification
Renowned globally for its innovative technologies, Sécheron ensures the protection and reliability of high-power electrical equipment by delivering complete substation assemblies.
Focusing on the power supply and protection of DC and AC traction substations, the company’s portfolio encompasses switchgear and distribution boards (such as DC high-speed circuit breaker panels, disconnect switch panels, load break switch panels, AC metal-clad switchgear and outdoor railway switches), voltage limiting devices, control and protection relays, as well as advanced supervision tools (such as control command and local SCADA, and stray current monitoring systems).
With decades of accumulated expertise in traction electrification and power electronics, Sécheron’s engineering teams provide dynamic network simulations and studies, enabling the optimisation of all traction power subsystems, from design to operation.
Sécheron’s installed equipment spans the globe and operates on many railway networks, serving mass transit, metro, tramway and light rail systems, in most major cities.
Power Conversion Systems for energy efficiency and regeneration
In the realm of power conversion, Sécheron delivers a comprehensive range of solutions that enhance energy utilisation and grid interaction for electrification systems. The portfolio includes AC/DC bus ducts, air-cooled and water-cooled rectifiers, IGBT and thyristor inverters, automatic assured receptivity units, as well as innovative reversible converters.
For rail applications, Sécheron’s energy recovery systems capture braking energy and either feed it back into the network or store it for reuse, reducing peak power demand and improving overall energy efficiency.
Based on the same advanced power electronics expertise, these regenerative technologies are also deployed in other highly demanding applications, such as mining electrification, DC grids, hydrogen production by electrolysis, or nuclear fusion.
Through these robust and versatile solutions, Sécheron supports operators across various energy-intensive industries in achieving sustainability objectives, while maintaining high reliability and performance.
Project continuity through a full range of After-Sales Services
Thousands of customers place their trust in the excellence of Sécheron’s products every day. But Sécheron is not only an equipment manufacturer. Beyond hardware, the company’s value-added services play an essential role in optimising asset performance and extending the lifecycle of substations, while reducing the operational risks and costs for end-users.
Comprehensive offerings include spare parts and obsolescence management, repairs and calibration, service level agreements and maintenance contracts, modernisation and retrofit projects, technical support and engineering services, training and e-learning, as well as digital services.
The Intelligent Operation & Maintenance System (IOMS) developed by Sécheron is a digital platform for data acquisition and analysis, enabling real-time performance monitoring and predictive maintenance of traction power assets. By delivering precise operational insights, it enhances equipment maintainability and reliability throughout the entire lifecycle, maximising uptime and streamlining energy management in demanding rail environments.
