New global player in rail infrastructure

 

For more than 25 years, Mosdorfer has been building a portfolio of safe and reliable power-delivery systems designed specifically for electric railways.  

For the renowned manufacturer of transmission and distribution-class overhead powerline equipment, this focus on rail took a huge step forward in December 2021 with the acquisition of the Rail Products division of the Pfisterer Group, manufacturer of high-voltage cable accessories and a system provider in the field of energy infrastructures. 

According to Mosdorfer Graph managing director Anthony Jones, bringing together the products and also the R&D and manufacturing expertise of Mosdorfer and Pfisterer Rail has created a global leader in railroad infrastructure.   

“The acquisition includes around 70 employees at three locations in Spain, Italy and the UK, and ideally complements the team and product range of Mosdorfer, which is part of the Knill Energy group of companies based in Weiz, Austria,” he said. 

“With its products and systems, Knill Energy makes a significant contribution to the smooth supply of electricity worldwide.  

“The core competencies of the Knill Energy companies lie in the development, manufacture and sale of damping systems and fittings for high-voltage overhead lines, distribution systems for low and medium voltage, monitoring systems and digital services for line management, components for overhead switchgear, rail infrastructure equipment and cabinet systems for energy, telecommunications, traffic and control systems.” 

The Pfisterer Group invented the patented automatic spring-tensioning device known as Tensorex C+. 

Through the interaction of a spiral spring and a cam (pulley with variable radius), Tensorex C+ exerts a constant pulling force on the wiring system throughout day/night temperature fluctuations and seasonal variations.  

This compensates for changes in length and keeps the contact line at a constant geometry. The high precision of the system response means that the actual operating point can be read at a glance any time – no re-measuring is necessary.  

With this system there is no need for regular lubrication or greasing. Once in service, the system is maintenance-free.  

Complementing the tensioning systems is a huge range of catenary and cantilever systems, customised rail insulators, section insulators, plus an extensive variety of clamps and connectors for metro rail, light rail and high-speed rail networks worldwide.
