Project Information
Overview
CG has Low Voltage Slip Ring electric motors ranging from 3.7 kW to 350 kW in both TEFC (IP55) & Drip Proof (IP23) construction. These motors are designed with new Slip Ring and brush gear arrangement for trouble free operations and long lasting brush life , Slip Ring are moulded in epoxy-based insulation and excellent stability in operation at high temperature and have very good anti tracking property .
