Welcome to the official website of SESTO Ltd. from Łódź
We are a leader in providing electrical power systems and devices for rail transport
We offer design, execution, and maintenance services...
Since 2008 we have been committed to the vision that has guided us since the company’s inception. We bring together an experienced design and execution team, and most importantly, we are a manufacturer of modern control equipment for railway and urban transport.
Our project team’s many years of experience guarantee success in executing complex infrastructure projects. We specialize in the design, construction, and modernization of power supply facilities for railway systems (3 kV DC and 2x25 kV AC) and urban traction networks (600V DC and 750V DC), including security, automation, and remote control systems. We execute projects for cable and overhead lines for high voltage (HV), medium voltage (MV), and low voltage (LV), as well as projects related to LV energy.
We manufacture protective equipment for traction substations, measuring and control devices, and supply systems for electric heating of switches and lighting of railway areas. We specialize in building Dispatch Centers managing the power supply of urban traction networks and Railway Local Control Centers (LCS). We collaborate with a wide range of suppliers that guarantee the highest quality of the produced electronic equipment.
We have a team of experienced programmers, analysts, and Big Data specialists. We are the authors and suppliers of advanced eco-driving software designed for railway carriers, with the main goal of providing support in improving key indicators affecting the quality and efficiency of services, and also, very importantly nowadays, increasing their energy efficiency.
We are among the companies that have gained the trust of the European Organization for Nuclear Research (CERN). Since 2018, Sesto has continued its fruitful collaboration with the Department of Electrical Apparatus at the Łódź University of Technology, working with this largest scientific institution in the world. The production of ultramodern devices of the highest quality, reliable, and critically important for the success of research at the LHC is a significant challenge for us but also a source of pride that we are part of this largest global research laboratory.
… but above all, we are a team united by passion and commitment.
