Description

technical field

[0001] The invention belongs to the technical field of transportation vehicle accessories, and in particular relates to a method for preparing a carbon / carbon pantograph slide plate for an electric locomotive. Background technique

[0002] Skateboards are mainly divided into metal-based skateboards and carbon-based skateboards according to their materials. Metal-based skateboards include pure metal skateboards and powder metallurgy skateboards; carbon-based skateboards include pure carbon skateboards and metal-infiltrated carbon skateboards. Among them, due to the similar material and strong affinity with the contact wire, the pure metal slide plate wears the contact wire very seriously, and has been eliminated at present.

[0003] The development of railways toward electrification and high-speed is to meet the needs of national economic and social development. The pantograph-catenary system of an electrified railway is one of the key links that determine th...
