Introduction About us Our company specialises in designing and manufacturing Medium and High Voltage electrical equipment for the following sectors: Railways, Infrastructure, Renewable Energy,

5 Introduction About us Our company specialises in designing and manufacturing Medium and High Voltage electrical equipment for the following sectors: Railways, Infrastructure, Renewable Energy, Electricity Companies and Large Industry in general. MESA was founded in Mungia (Spain) in 1947 as a response to the growing energy demand at the time. MESA has been working closely with the main electricity companies in Spain ever since it started up, seeking out innovative products for the electricity market. As part of this constant search for innovation and design, MESA opened the first High Voltage laboratory in Spain in The first developments in GIS switchgear began here, in addition to our expansion into other new sectors such as railways, high speed trains and renewable energy. We are currently a strategic supplier for 55 kv High Speed substations and a benchmark for the main metro systems in Spain. MESA is undergoing major international expansion in preparation for future challenges: Smart Grids, Power Houses, Offshore and other renewable energy sources, and high speed travel on the international market. A long history of R&D&i Here at MESA we believe that only by being at the vanguard of technology we can offer our customers the most innovative and smart solutions that respond to the challenges faced on every project. R&D&i has been part of MESA's DNA since it began, and this has led to us being leaders in our home market by setting the pace for designing Medium and High Voltage equipment that others have later followed. We have travelled a long road alongside the main electricity companies and players in the electricity sector, seeking out solutions that best suit their requirements. The high voltage laboratory at the R&D&i department has allowed us to perform the electrical, mechanical and climate tests needed to guarantee the quality and reliability that our customers expect from the equipment we design. Quality At MESA we are convinced that only maximum quality in the manufacturing of our equipment can ensure its high reliability. MESA introduced its quality policy over 30 years ago, creating the company's first quality manual, and since then it has been continually developed and updated to achieve total quality. The MESA quality management system is certified in accordance with the ISO 9000 standard and we continue to work every day to improve constantly every process, from designing the equipment we manufacture to our after-sales service, to ensure maximum customer satisfaction. The Environment All our products have been designed with the environment in mind: the materials used are identified and can be easily separated for recycling. MESA's environmental management system is certified in accordance with the requirements set out in the ISO standard. Flexible products that are optimised for customer requirements Offering innovative solutions since 1947 In-house HV lab 365/24/7 after-sales service 10% of staff working on R&D&i Excellent training programmes 5

The medium voltage units are located in the traction substation control building in the medium switchgear room. Two-phase switchgear with a maximum service voltage of 55 kv between phases is normally used with SF6 insulation for controlling and protecting the power transformers, as well as protecting the catenary. 36 kv single-phase switchgear is used to protect the auxiliary service transformers.
