Cableizer ®

Attenuation factor for crossing

As $\gamma$ depends upon the current in the rated cable, which is to be determined, an iterative solution is necessary, using as a first estimation of this current the rated current when the heat source is assumed to be parallel to the rated cable $\Delta\theta_0$.
