A capacitor is formed whenever you have 2 conductors separated by a dielectric. Since a cable fits that description, 2 wires with an insulator to keep them from touching, the cable will have some amount of capacitance. The amount is determined by the surface area of the conductors, how close they are together, and what dielectric is used. To increase capacitance use larger surface areas and put them closer together.
The capacitance of your cables is therefore determined by how they are constructed.
