## Buildings.Electrical.Transmission.MediumVoltageCables.Generic

Data record for a generic medium voltage cable

### Information

This is a base record for specifying physical properties for medium voltage commercial cables. New cables can be added by extending it.

For medium voltage cables, the geometric properties of the cable and the material are specified. For example some of the properties that are specified are:

    Rdc   : Characteristic DC resistance at T = T_ref[Ohm/m]
    T_ref : Reference temperature of the material [K]
    d     : Inner diameter [m]
    D     : Outer diameter [m]
    Amp   : Ampacity [A]

other properties such as the geometric mean diameter GMD and the geometric mean radius GMR are by default computed using functions, but this can be overriden.
