Type SS3B Electric Locomotive
  Type SS3B electric locomotive,consisting of two identical six-axle locomotives, through mechanical,electricand air-braking pipeline by fixed multiple connection.It is an integrated twelve-axle locomotive for heavy haul of freight on main line.Both driver¡¯s cabs have the same control functions.Each loco can act as a six-axle locomotive independently which is originated from SS3 electric locomotive after cutting down one driver¡¯s cab.The locomotive decreases a great deal of circuit by increasing Train Communication Network Control (TCN) system. Moreover the condition of main components and the imformations of malfunction can be displayed. So SS3B electric locomotive features advanced techniques, high reliability and easy maintenance.

  Every locomotive body is divided into such senven compartments as driver¡¯s cab, NO.1 auxiliary equipment compartment, NO.1 high voltage room, transformer room, NO.2 high voltage room, NO.2 auxiliary equipment compartment, NO.3 auxiliary equipment compartment, roof locomotive equipment and bottom locomotive equipment.

  Type SS3B electric locomotive is characterized by excellent starting as well as good traction and advanced techniques£¬higher reliability ,perfect versatility and easy maintenance.
