Product Description:

Railway Digital Signal Cable

 

Product Description

Application

Cable is available for railway signal system connecting equipments and control facilities, could carry out the transportation of control information and electronic at 1MHz (analog signal), 2Mbit/s(digital signal), rated AC voltage 750V or DC 1100V and below.

 

Executive Standard

  TB/T3100-2004

Operational Performances:

  Ambient temperature of cable is -40~ +60°C,installation temperature no less than-10°C

  Long-term working temperature no more than +70°C,

  Cable allowed bending radius: 10 times of O.D. for non-armored cable, 15 times of O.D. for armored cable.
