recordGeneric
Data record for a generic low voltage cable
Extends from Modelica.Icons.MaterialProperty (Icon for property classes), Buildings.Electrical.Transmission.BaseClasses.BaseCable (Record that contains the properties of a generic cable).
Information
This is a base record for specifying physical properties for low voltage commercial cables. New cables can be added by extending the it.
For low voltage cables, only the characteristic resistance and reactance are specified.
