CURRENT COLLECTION MATERIAL OF PANTOGRAPH CONTACT STRIP

摘要

PROBLEM TO BE SOLVED: To provide a current collection material of a pantograph contact strip, having both a sliding characteristic and a current collection characteristic and improving a mechanical characteristic.

SOLUTION: The current collection material of the pantograph contact strip has a substrate equipped with a sliding surface contacting an overhead current line for power transmission and the substrate is made of a carbon fiber reinforced carbon composite material. In the current collection material, the carbon fiber reinforced carbon composite material includes a main sliding portion 2 disposed on the center portion and an auxiliary sliding portion 3 disposed on the peripheral edge of the main sliding portion 2, the carbon fibers in the main sliding portion 2 all extend in a vertical direction for the sliding surface, and some carbon fibers in the auxiliary sliding portion 3 extend in a non-vertical direction for the sliding surface.
