    Cables crossing module

    The cables crossing module (CYMCAP/XING) enables the user to determine the steady-state ampacity of two underground cables crossing each other in compliance with IEC standard 60287-3-3.

Determine the steady-state ampacity of cables crossing 

When two cables cross each other, each behaves as a heat source for the other one. The amount of generated heat, the vertical distance between the crossing cables and the crossing angle are the main parameters influencing the crossing rating.

In the absence of crossing calculations, the general practice is to use the conservative result where the circuits are assumed to be parallel. When cables are parallel, the thermal interaction is maximum. The conservative approach unnecessarily de-rates both cables. 

With the cables crossing module, users can achieve ratings up to 20% higher than the conservative ampacities obtained based on the parallel installation scenario. 

Highlighted features:

  • Models two cables crossing each other in the same installations
  • Models cable crossings directly buried underground, in buried ducts and in buried pipes underground
  • The rating methodology adheres to the IEC standard 60287-3-3
