dielectric strength

SF gas has a much higher dielectric strength than air.

Fluorocarbons also have low surface energies and high dielectric strengths.

In physics, the term dielectric strength has the following meanings:

The extensive use is due to its high dielectric strength and average thermal conductivity.

The dielectric strength of class 2 ceramic and plastic film diminishes with rising frequency.

The dielectric strength depends on temperature, frequency, shape of the electrodes, etc.

The dielectric strength of these capacitors can reach into the four-digit voltage range.

Porcelain has a dielectric strength of about 4-10 kV/mm.

Advantages include flexibility and high dielectric strength.

Wet oxidation also yields a lower-density oxide, with lower dielectric strength.

Once the voltage exceeds the dielectric strength of the gases, the gases become ionized.

Some spark plugs are manufactured without ribs; improvements in the dielectric strength of the insulator make them less important.

Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material.

Some fish papers incorporate mica layers to increase the dielectric strength while still giving good mechanical strength.

Using this device, material parameters such as permittivity, doping, oxide charge, and dielectric strength may be evaluated.

We see that the maximum energy is a function of dielectric volume, permittivity, and dielectric strength per distance.

Resin insulation has greater dielectric strength than paper and requires less stress control at voltages below 25 kV.

These defects further weaken the dielectric strength of the material, enhance the electrical stress, and accelerate the PD process.

Dielectric Strength of Air (with multiple references)

Above a particular electric field, known as the dielectric strength E, the dielectric in a capacitor becomes conductive.

Glass has a higher dielectric strength, but it attracts condensation and the thick irregular shapes needed for insulators are difficult to cast without internal strains.

In SI, the unit of dielectric strength is volts per meter (V/m).

Sulfur hexafluoride has been used in electrostatic loudspeakers because of its high dielectric strength and high molecular weight.

Wax paper's particularly high dielectric strength makes it a practical electrical insulator, although modern materials have surpassed and mostly replaced it.

Once the electrical stress exceeds the dielectric strength of the plastic, some portions suddenly become conductive in a process called dielectric breakdown.
