電氣強(qiáng)度（Dielectric strength），指擊穿電壓比上擊穿樣品的厚度等于樣品的電氣強(qiáng)度。

The dielectric constant is a proportional constant that exists between the displacement of electricity and the strength of the electric field. This constant in free space (a vacuum) is 8.85 ? 10 ^ -12 times the method pull per meter (F/m). In other materials, the dielectric constant may vary greatly, often much greater than the value in vacuum, and its symbol is eo. In engineering applications, the dielectric constant is often expressed in the form of relative dielectric constant rather than absolute value. If eo represents the dielectric constant of free space (8.85 ? 10 ^ -12 F/m), and e is the dielectric constant in the material, then the relative dielectric constant (also known as the dielectric constant) of this material is given by the following equation: ε 1=ε/ε o=ε ? 1.13 ? 10 ^ -11. Many different substances have dielectric constants exceeding 1. These substances are commonly referred to as insulating materials or insulators. Commonly used insulators include glass, paper, mica, various types of ceramics, polyethylene, and specific metal oxides. Insulators are used in capacitors and transmission lines for alternating current (AC), acoustic waves (AF), and radio waves (RF).

Instrument information for testing dielectric strength

The dielectric breakdown strength tester meets the requirements of GB1408.1-2006 and is mainly suitable for testing the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, glass, insulating paints, etc. under power frequency voltage or DC voltage; This instrument is controlled by a microcontroller and can quickly and accurately collect and process various data during the experimental process. It is a testing instrument that can be accessed, displayed, and printed.

Electrical strength refers to the ratio of the breakdown voltage to the thickness of the breakdown sample, which is equal to the electrical strength of the sample.

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

In insulation materials, pure materials can withstand the maximum electric field under ideal conditions without damage (i.e. without experiencing failure of their insulation performance).

For the specific configuration of dielectric materials and electrodes, the minimum applied electric field that causes breakdown (i.e., the applied voltage divided by the electrode separation distance).

The theoretical electrical strength of a material is an inherent property of bulk materials and is independent of the construction of the material or electrode to which an electric field is applied. This' intrinsic dielectric strength 'corresponds to the value measured using pure substances under ideal laboratory conditions. During breakdown, the electric field releases bound electrons. If the applied electric field is high enough, free electrons from background radiation may accelerate to a speed that releases additional electrons during collisions with neutral atoms or molecules, known as avalanche breakdown. The breakdown occurs quite suddenly (usually in a few nanoseconds), leading to the formation of a conductive path and destructive discharge through the material. For solid materials, breakdown events are significantly reduced, and even their insulation ability is damaged.
