DC electric locomotives should be equipped with metal ceramic contact plates and carbon inserts. Metal ceramic plates should be installed on the ChS2, VL22, VL82 and VL10 locomotives, as well as the VL8 in mountainous areas, where currents are heavy. All other dc electric locomotives should be equipped with carbon inserts. The conversion of the dc locomotives to metal ceramic plates and carbon inserts can reduce contact wire wear by a factor of 2-2.5 and avoid the use of copper contact plates with SGS-O dry graphite lubrication.
