frost® Ground Contacts

The mechanical structure of our frost® ground contacts meet effective national and international standards and directives. Material pairing is consistently optimised.

The design resp. working direction of the carbon brush is distinguished between axial and radial active contact system.
Conventional round brush designs have been replaced by multiple brush designs in the area of standard applications. The reasons for this are, among others, the increased possible power transmission and in part, the simpler make-up of the contacts.

We have consistently continued to develop the successful path to multiple brush contacts and in the process, devised the successful frost® pressure system.

frost® Ground Contacts with axial effect

frost® Ground contacts with axial effect are used for internal and external mounted wheel sets. They direct the reverse current flow via the front side of the axle to the wheelset axle so that it flows into the rail through the wheels.

frost® Ground Contacts with radial effect

frost® Ground contacts with radial effect are used if the clearance zone is limited, special bogie designs make this essential or the customer specifications require it. They direct the reverse current flow directly into the wheelset axle, from where it can flow into the rail via the wheels.
