Geometrical nonlinearity means that you have to take the change of geometry into account. Basically, it is the difference between nominal stress (and strain9 and true stress (or strain). So if the cross-section of your cable changes when it is loaded, the stress should be calculated as force/current cross section. I don't think that there is anything special about cables compared to other structures - if you ave a special cable element, choosing non-linear geometry will take care of this.
A general rule of thumb is that you need to use nonlinear geometry when strains exceed 5%, but this is not a hard rule.
