Energy Systems
that shape the future
More than 75 years of Expertise
Energy is the engine that powers our modern lives. For more than 75 years, Mosdorfer has been developing and manufacturing fittings and systems for high-voltage overhead lines—thereby making a decisive contribution to safe and efficient energy transmission.
We understand the challenges associated with the global expansion and modernization of energy grids and offer customized solutions at the highest technical level. At our state-of-the-art production sites, we manufacture everything 100% in-house — from raw materials to the finished product—while meeting the strictest quality standards.
As Mosdorfer, we are part of Energy Systems — a business unit of the Knill Group that unites leading brands such as Mosdorfer, Damp, and Lorünser. Together, we cover key areas of modern energy grids—from overhead line systems to switchgear. This network enables us to share expertise, accelerate innovation, and sustainably strengthen global energy systems.
Connections that move energy
With decades of experience, innovative strength, and a global presence, we are shaping the energy infrastructure of today and tomorrow.
A functioning power supply is indispensable and taken for granted today. To meet this demand, systems are needed that operate reliably even under the harshest conditions. Mosdorfer products ensure that electrical energy is transmitted safely and without loss, even at critical interfaces.
We develop and manufacture fittings and system solutions that ensure a reliable connection between conductor cables and towers—under all conceivable conditions: whether in icy high-altitude regions, arid desert areas, or under extreme wind and weather conditions.
Our product systems are used worldwide and have proven themselves at voltage levels up to 1,200 kV AC and 750 kV DC. Thanks to state-of-the-art development and manufacturing technologies, we offer solutions characterized by the highest quality, durability, and safety—thus making a decisive contribution to the stability and performance of modern power grids.
Mosdorfer stands for experience, innovation, and uncompromising quality—for 75 years, we have been developing products that deliver electricity where it is needed.
Suspension and Tension Strings
Our string fittings and connection systems ensure that high-voltage overhead lines operate safely and efficiently under all conditions—whether in high-voltage direct current (HVDC) or high-voltage alternating current (HVAC) transmission.
Damping and Vibration Systems
Our custom-designed damping systems—ranging from vibration dampers to damping spacers—reliably protect lines against wind-induced vibrations, partial-field vibrations, and cable sway. Using state-of-the-art simulations, field tests, and real-time measurements, we develop solutions that are precisely tailored to your infrastructure.
Additional Systems
In addition to its core portfolio, Mosdorfer offers practical system solutions that make overhead power lines even safer and more reliable. These solutions protect against phase collisions, improve visibility for air traffic, and ensure the safe distribution of power in low- and medium-voltage systems.
Mosdorfer worldwide
With our strong, global network of locations, we are always close to our customers. This international presence enables us to respond flexibly to requirements, streamline processes, and ensure our consistently high quality standards worldwide.
Mosdorfer’s headquarters are located in Weiz, Austria – the place where our company’s roots have been for over 300 years. Today, we have a global presence with production sites in Europe and Asia, as well as sales offices in Europe, Asia, North America, South America, and Australia.
This is how we combine regional proximity with global expertise – for solutions that work reliably anywhere in the world.
