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.

High Voltage Air Variable Capacitors 1362pF/ 3.7kV Amplifier/Tuner
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.

How to estimate or measure the max voltage of an air variable capacitor. Ask Question Asked 7 years, 6 months ago. Modified 7 years, 6 months ago. Viewed 3k times. Actual high voltage you will see of course depends on the reactance and input power to the antenna (a little circuit analysis may be in place) along with frequency needed to.
1558 Air Variable Capacitor, 952 pf, 13 plates, 1kv, 50F30, MFR E F
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.

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.

Description This is our MFJ-23, a larger low loss butterfly loop tuning capacitor. The capacitance is variable from 18-136 pF. This low loss butterfly loop tuning capacitor has a voltage rating of 4200 Volts rms. Built-in insulator feet give 1-inch of space under the bottom of the capacitor allowing convenient mounting and high voltage insulation.
High Voltage Air Variable Capacitors 22360pF/ 1KV Amplifier Tuner
Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser ), or as a variable reactance, e.g. for impedance matching in antenna tuners .
