れていた。However, in recent years, the speeding up of electric vehicles has been remarkable, and along with this, the pantograph 1
Since the current collection per unit increases, the wear of the contact plate tends to increase remarkably. In addition, the number of pantographs tends to be reduced in order to prevent an increase in noise due to the increase in speed, and this also causes an increase in the abrasion of the contact plate along with an increase in the current collecting current. Furthermore, the increase of the current collection increases the Joule heat due to the contact resistance between the contact plate and the trolley wire, which may cause heating and fusing of the trolley wire.
There has been a demand for a pantograph siding plate material having wear resistance far superior to that of a conventional pantograph siding plate material and having a low resistivity.
