SS7c Modified Electric Locomotive (神马在线)

Introduction

SS_7C modified electric locomotive is based on SS_7c electric locomotive, series circuit of main circuit traction motor is changed from full controlled plus half controlled second section bridge into full controlled plus half control third section bridge; regenerative braking is changed into resistance braking; the modified locomotive is AC-DC driven 4800kW six-axle passenger and freight electric locomotive with the high speed of 120km/h after the controlled circuit is changed from electric control into computer control.

Main technical characteristics：
