Capacative cable?

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.

Maybe, it depends on the construction. 2 flat ribbons stacked on top of each other and very close together

would have a lot more capacitance than the same 2 ribbons side by side

The manufacturer should be able to tell you the capacitance of the cable and you can then compare it to others to see if it is relatively high or low. I looked at their website and it doesn't say.
