In a particular application, the pantograph gasket is mounted to a designated location at the top of the vehicle at the pantograph junction and serves as a connecting contact wire to deliver electrical energy to the train. Due to good conductivity of graphene, the contact resistance of the coating part is small, the heat field concentration condition of the joint is weakened, and the graphene material is good in toughness, high in mechanical strength and not easy to age and crack. Through the improvement of the structure of the base plate, under the premise of not influencing the installation and the normal use, the electric field concentration condition on the outer surface of the base plate is improved, the position of the maximum field intensity is changed, the fault rate is reduced due to a plurality of factors, and the service life is prolonged.
