Description

Overview

Railway applications carbon brush holders — brush-holder solutions across the full rail electrical spectrum: traction motors (commutator), traction alternators & motor-alternator sets (slip rings), auxiliary drives and grounding brush gear. High-grade brass/copper bodies hold brushes under spring pressure for stable contact in demanding rail duty.vocarbon.comООО ВИК-Энерго

Duty Classes

Traction (DC motors, commutator): GE-752, EMD D29/D31/D77, ZD/ZQ, HXD-class
Slip ring (alternators / MA sets): field excitation contact
Auxiliary (compressors, pumps, AC, blowers): low-current-density duty (R783-class grade per Morgan rail guide)
Grounding (ERCU / earth return): ground brush holders with cable terminals (Mersen rail class)
