recordBaseCable
Record that contains the properties of a generic cable
Information
This record contains the basic properties to describe a commercial cable.
The low voltage and medium voltage cables extends this base records and add other specific parameters like the geometrical properties.
The record contains four partial replaceable functions used to compute the properties of the cable such its resistance, inductance or capacitance.

Revised structure of the record, not it contains just the minimum amount of information needed to describe a cable.
It also contains partial function that compute the properties of the cable. -
