Product Details

APPLICATION

It is suitable for the control circuit of transmission railway signal, audio signal, or automatic signal device with a rated voltage of 500V or 1000V DC. The railway signal cable with comprehensive sheath and aluminum sheath has a certain shielding performance, which is suitable for laying in electrified sections or other areas with strong electric interference.

 

DESCRIPTION

Sizes: (4 --- 61) core x 1.0mm
1. According to the type of sheath, the signal cable includes plastic sheath (pty03, pty23), comprehensive sheath (PTYA23, ptya22), aluminum sheath (ptyl23, ptyl22) signal cable;
2. The digital signal cable is divided into the plastic sheath (sptyw03, sptyw23), comprehensive sheath (sptywa23) aluminum sheath (sptywl23), internal shielding (sptywp03 or sptywp23, sptywpa23, sptywpl23) digital signal cable.

USAGE FEATURES

  • The use environment temperature of the cable is -40ºC~+60ºC.
  • The long-term working temperature of the cable conductor should not exceed +70ºC.
  • The ambient temperature of cable laying: the poly-chlorine outer sheath cable should be not less than 0ºC; the poly outer sheath cable should be not less than -20ºC.
  • The allowable bending radius of the cable: non-armored cable should be not less than 10 times the outer diameter of the cable; armored cable should be not less than 15 times the outer diameter of the cable. 
  • The ideal coefficient of an integrated sheathed railroad signal cable is ≤ 0.8; the ideal coefficient of an aluminum sheathed railroad signal cable is ≤ 0.3.
