I can model a coax cable in LT spice using the inbuilt model or a lumped collection of R C and L.
But the cable I want to model has no overall screen insulation, and somewhere between most and hardly any of it is very tightly wound onto a drum, so the outer on the drum is all 'shorted' together. The outer is steel and has the same order of resistance as the copper inner.
That means there is part of the cable which looks like, I suppose, a mass of steel with an embedded coil.
I don't have a cable to hand.
How would you go about modelling this? I suppose that for the wound section, the R reduces, the C remains the same, but I'm not sure what to think about the L.
Cheers
