Air Spaced Variable Capacitor Uses
Rated Voltage. Run capacitors and start capacitors feature various working voltages, and the voltage and price are often correlated. Modern residential heating and air conditioning systems typically feature run capacitor voltage ratings of 370V or 440V and start capacitor voltage ranges of 125V, 250V, or 330V.

A high operating voltage requires that the distance between plates is sufficient to avoid electrical breakdown of air. If breakdown occured, it would cause sparking between the plates, the capacitor would not work properly and could even get damaged by the electrical arc.
☑ High Voltage Air Variable Capacitor
Description: Standing 4.5" high by 4.5" wide, with typical lengths of over one foot, the M90 is our largest standard configuration of air -dielectric variable capacitor in terms of physical size, and can withstand voltages of up to 11000Vrms. The latest revision of the M90 AC Rated Voltage (WVAC): 10000 volts Applications: RF / Microwave Capacitors

More importantly, air capacitors have a low breakdown voltage. However, one variant of air variable capacitors is unique because of its high current rating. The design of variable split-stator —or «butterfly»— capacitors is such that no RF conduction currents flow through the bearings of the rotor. In low to moderate power applications.
Capacitor 365pF, Variable Amplified Parts
High-voltage capacitors are key components for circuit breakers and monitoring and protection devices, and are important elements used to improve the efficiency and reliability of the grid. Different technologies are used in high-voltage capacitor manufacturing process, and at all stages of this process polymeric films must be used, along with an encapsulating material, which can be either.

For high voltages and currents the use of Capacitors with wiper contacts is not recommended. That's why they use capacitors in series. The pro for series's capacitors is that the voltage rating is doubled. The anti is that the value of capacitance is divided by 2.
