Service, maintenance and adjustment

We provide comprehensive warranty and post-warranty service for SERW products. Our experienced experts will do their maximum to ensure that you can rely on the error-free functioning of disconnectors at all times throughout their service life.

The first preserved mention of craft production on the territory of the company SERW dates back to the year 1578. Subsequently, production at the site undergoes further development through the ownership of the noble Waldstein family, focusing on metal production, until the first significant milestone, which was the entry of Emil Škoda and thus the establishment of the Škoda Works. In the 1970s, Škoda moved its production of electrotechnical equipment for the energy sector from Plzeň to Sedlec, thus beginning a chapter of the development and production of equipment that continues up to the present day.


This information only serves to illustrate that SERW is building on historical foundations of which it is justifiably proud. Thanks to its long-standing and developing expertise in the development and manufacture of disconnectors, earthing switches, and switches, the company is now one of Europe's leaders in products and equipment for distribution and transmission systems.


With the entry of a new owner at the beginning of 2024, we have reflected these values not only in a new logo, but also in a new philosophy and strategy for the company's development. We are proud of our history, we are proud of our present, and we are ready for our future. Our main goal is to be a strong and stable partner for our customers. We want to build on technical development, manufacture high-quality products with top parameters and a long service life, and provide high-quality warranty and post-warranty service. Our goal is to become one of the world's leading manufacturers of disconnectors, earthing switches, and other applications for high and extra-high voltage.


In accordance with the owner's objectives defined in our strategy, we are ready to respond to the growing demand for reliable and innovative solutions for the future of energy transmission, which are an integral and key part of the transformation of European and world energy infrastructure, with a focus on a successful transition to a sustainable future. At the same time, we apply the principles of an energy self-sufficient society and minimizing the carbon footprint as part of development investments in our company.


But it is not just about investing in a sustainable environment. It is mainly about our employees, and at SERW, they come first. We will devote a lot of attention to them in the coming years, whether in social development, professional development, training, or ensuring safe working conditions. Our goal is to create an environment where our people not only feel valued, but where they can grow and develop their skills so that they can be proud of their work and the company they work for.


We believe that satisfied and high-quality employees are the key to the long-term success of the entire company. “The future is in our hands and it is up to us how we will handle this opportunity…”
