Pantagraph contact strips are indispensable parts for electric train in their collectors on top of pantographs to collect electrical current by contacting with trolley wire.
Not only electrical conductivity, wear resistance, and arc resistance property, contact stripes are required the performance to bear harsh weather condition in outside.
