B-COMMAND slip rings series EXD

The slip ring EXD was developed especially for use in silos. Various materials for rings and busts enable the transmission of high electrical power, signals and data from BUS systems.

The EXD is approved for zones 21 and 22:
Zone 21 is an area in which a hazardous explosive atmosphere in the form of a cloud of combustible dust in the air may occasionally occur during normal operation.
Zone 22 is a place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

The cable exit of the brushes is via one or two axial, explosion-proof cable glands on the bottom of the housing. The rings are wired through the central tube, also provided with an explosion-proof cable gland. The cabling of the rings is already fully implemented and has a standard length of 2 meters. This can be modified according to customer requirements. Plug solutions are also possible.

The separation between rotor and stator is centrally located on the underside of the base part. Within a radius of 75mm is the rotating center tube, on which the rings are mounted above in the interior of the housing. The brushes are fixed above on the bottom part.

Two module sizes are available with the outputs 7A and 34A. Rings and brushes, which are made of copper graphite as standard, can be coated with a silver or gold alloy. This increases the contact quality and has a positive effect on the wear properties.

Especially for the EXD, an optional anti-condensation heater is available, which prevents the formation of condensation water and thus corrosion.
