What is cable capacitance?
Definition: Cable capacitance is defined as the measurement of the electrical charges stored within it. The capacitor in the cable is constructed by two conductive material which is separated by an insulator or dielectric. The capacitance of the cable determines the charging current, charging KVA, and the dielectric loss.
How many capacitances does a cable have?

Between each of the two inner conductors and the shield is an added capacitor. In other words, two more capacitors are added to the first capacitor. In any capacitor, the quantity of electrons does not determine the capacitance; the capacitance, combined with the voltage, determines the number of electrons and positive charges that are accumulated.
