WEAR OF ARC RESISTANT SINTERED COPPER ALLOY FOR PANTOGRAPH

The wear of pantograph contact-strip occurs under sliding electrical conditions and is influenced by arc caused by loss of contact. One of the problems encountered in using contact-strips in the cold districts has been the unusual wear caused by arc between the contact-strip and the frosted overhead wire. To overcome the problem, new contact-strips were formulated. They are sintered copper alloys containing 8-15 wt% of Cr of Fe-Mo alloy to improve wear resistance and 3-5 wt% of MoS sub 2 or matte, in place of graphite, to improve arc resistance. Their wear rates and arc erosions in the laboratory tests were, in most cases, lower than 2/3 of those of the regular contact-strip.
