Grounding Systems for Railways/Traction
Reliable shaft grounding, earthing contacts and CFG systems
Grounding systems with maximum durability
Only with a perfectly matched grounding system are return, safety and signal currents safely and reliably discharged. It is therefore not without reason that grounding contacts can make a decisive contribution to the economical and safe operation of your rail vehicles. These grounding systems or grounding contacts are mounted either at the end of the axle (axial) or at the gearbox (radial). At Schunk, such solutions have been established for years and are part of a large repertoire.
Grounding systems must work reliably over as long a period as possible. At Schunk, you receive durable solutions for all common installation situations and interfaces. It is therefore no coincidence that leading vehicle manufacturers in the rail/traction sector rely on grounding systems from Schunk. Because with our technology, we have revolutionized the transmission of signal currents and ensured new dimensions in maintenance intervals.
Perfect protection with Schunk shaft grounding system “CFG”
Inverter-controlled drive systems generate currents that are small in magnitude, but at the same time have vagrant voltages. Over time, these vagrant voltages can wreak havoc in rail vehicle drive systems. Our shaft grounding system, called Carbon Fiber Grounding system (CFG system), reliably diverts vagabond shaft voltages to the vehicle ground. It thus reliably protects rolling bearings and adjacent assemblies in transmissions and engines from damage. The unique structure of interwoven carbon fibers ensures optimum contact and high abrasion resistance.
