G7623 Trackside Communications Cables

 

Applications :

  • The cables are designed for limited fi re hazard applications for internal use within stations, buildings and equipment rooms.

Standards :

  • LUL Spec G7623 A2
 

 

Construction :

  • Conductors : Tinned annealed solid copper, 0.5/0.6/0.63 mm nominal diameter.
  • Insulation : LSZH Insulation.
  • Cabling Element : Two insulated conductors are twisted together to form a pair.
  • Stranding : Cables are composed of unit stranding.
  • Core Wrapping : Non-hygroscopic plastic tape with overlapping.
  • Outer Sheath : LSZH sheath.
