The mechanical structure of our frost® ground contacts fulfils the applicable national and international standards and directives. The material pairings are continually optimized.
In the construction or in the direction of working of the carbon brushes, a distinction is made between axial and radial operation contact systems.
In the area of standard applications, the traditional round-brush constructions have been replaced by multi-brush constructions. The reasons for this are the higher possible current transmission and the somewhat simpler construction of the contacts.
We further developed the successful principle of the multi-brush contacts and derived the successful frost® pressure system from it.
Axial frost ® Ground contact systems are mounted on the bearing housing or directly to the wheel, which requires a special design with own bearings and torque arm.
Depending on the space available, we recommend radial frost ® Ground contact systems as completely sealed.
