In view of the abnormal wear problem of catenary in a metro project,the present work carried out statistical a-nalysis of abnormal wear status and wear values,and equipment survey from the perspectives of both catenary and vehi-cles.It successfully determined that the direct cause of abnormal wear was electrical wear caused by high temperature and arc combustion,and formulated the corresponding countermeasures which helped significantly suppress the further deteri-oration of abnormal wear of catenary.
