7-napainen tuplavirranotin, 70A DC 60% RNHS kotelolle
The current conduction of the Multiconductor to the device to be fed is effected through the collector trolley. The contact with the flat copper conductors is maintained uninterruptedly by means of flexible, extreme wear-resistant carbon brushes manufactured from a specific bronze-coal alloy. The collector trolley is pulled into the Multiconductor by the moving machine to be fed and by means of a trolley towing arm mounted on to this machine.
For Multiconductor type RNHS7 special trolley with an elongated lower moulding are utilised.
