Impedance of Single Phase UEB cables

Impedance of Single Phase UEB cables

Impedance of Single Phase UEB cables

(OP)
Has anyone derived the self and mutual impedances of Single Phase UEB Cables i.e two insulated conductors wrapped by a concentric neutral. This is a common secondary conductor used for underground residential. I have tried contacting a manufacturer's engineering group but only obtained the self impedance. I've tried to calculate it from first principles using Carson's equations, but I am unsure how to treat the neutral wires, consider as a neutral wrapping each individual conductor? Any illumination on this matter would be tremendously appreciated.

RE: Impedance of Single Phase UEB cables

I don't know what it is UEB cable.May be USEB[ALUMINUM conductors?]or else.
