When selecting the safety sliding contact line collector, the collector is considered to be the manufacturer matching with the sliding contact line. Do not use the collector randomly, otherwise it will affect the normal operation of the train and burn the sliding contact line seriously.

The shoe on the collector is made of carbon base containing copper. After purchase, check the fit with the sliding wire. Since the collector itself is a consumable and will wear the shoe piece after long-term use, it is necessary to regularly check the wear degree of the shoe piece on the collector and replace it regularly.
