Abstract
The pantograph contact strip is a sliding current collecting component used in electric locomotive. Its performance is an important factor restricting the development of electrified railways toward high speed. This paper makes an introduction of the new developing composite material strips, points out the advantages and disadvantages of various materials, their limiting factors during using or bottlenecks in R&D and production, and gives prospect to the future development of pantograph contact strip materials in the end.
Highlights
As a component of current collection by friction, the pantograph contact strip is required to have good anti-friction, wear resistance and self-lubrication, as well as good conductivity and impact resistance
Since electric locomotives were put into operation, theory research and application study on pantograph contact strip materials have never ceased
Pantograph contact strip materials have developed from the original pure metal contact strip and powder metallurgy contact strip to the current mostly applied pure carbon contact strip and metal-impregnated carbon contact strip
Summary
As a component of current collection by friction, the pantograph contact strip is required to have good anti-friction, wear resistance and self-lubrication, as well as good conductivity and impact resistance. Since electric locomotives were put into operation, theory research and application study on pantograph contact strip materials have never ceased. Developed countries like Japan, Germany and France have made important achievements in the study of pantograph contact strips [1]. Pantograph contact strip materials have developed from the original pure metal contact strip and powder metallurgy contact strip to the current mostly applied pure carbon contact strip and metal-impregnated carbon contact strip. To meet the new demand, composite material contact strip develops rapidly [2,3]
