Performance and application of Nomex Braided Sleeve raw materials

When it comes to Nomex Braided Sleeve, most outsiders may not know it, but when it comes to maintaining and cleaning computer power cords, speaker and video cables, lighting, central air conditioners, refrigerators, automatic washing machines and other electrical appliances We may have some knowledge of products and optical cables, motorcycles, and vehicles, but not all of them. Let`s learn about the performance and application of Nomex Braided Sleeve materials.

The crystallized Nomex Braided Sleeve is a p-n junction formed by p-type semiconductor and n-type semiconductor. It forms a space charge layer on both sides of the page and establishes an electric field. When no additional voltage is applied, there are free electrons on both sides of the p-n junction. The spread current caused by the concentration difference is the same as the drift current caused by the built-in electric field and is in an electrical equilibrium state. When there is an external positive voltage limiter, the external electric field and the built-in electric field suppress each other, causing the spread of free electrons. The current increase creates a positive direction current.
When there is an external reverse voltage limiter, the external electric field and the built-up electric field are further strengthened, resulting in a reverse saturation current I0 within the reverse voltage range that has nothing to do with the reverse bias voltage value. When the voltage reaches a certain level, the electric field intensity in the p-n junction charge layer reaches a critical point and the growth process of free electrons occurs, forming a large number of electronic oxygen vacancy pairs and generating a large reverse penetration current. This is called the penetration condition of Nomex Braided Sleeve.
According to the commonly used semiconductor materials, they can be divided into germanium Nomex Braided Sleeve and Special Material Braided Sleeve. According to their different main uses, they can be divided into detector Nomex Braided Sleeve, rectifier Nomex Braided Sleeve, voltage stabilizing tube Nomex Braided Sleeve, and power switch Nomex Braided Sleeve. Casings, etc., according to the core tube structure, can be divided into point contact type Nomex Braided Sleeve, surface contact type Nomex Braided Sleeve and horizontal type Nomex Braided Sleeve. The point contact type Nomex Braided Sleeve is made of a thin The wire is pressed against the surface of the bright semiconductor chip.
A single pulse current is passed through, so that one end of the contact wire and the chip are burned together firmly, forming a "PN junction". Because it is a point contact, it can only be used for high-frequency and small-current power circuits based on smaller currents, such as the detection of tape recorders, etc. The PN junction area of the surface contact type Nomex Braided Sleeve is relatively large. In the power circuit, the rectifier is mainly used to convert AC current into DC power through a relatively large current. The planar type Nomex Braided Sleeve is a non-contact type. The same Special Material Braided Sleeve not only can pass a relatively large current, but also has relatively stable and reliable performance. It is mostly used in switches, single pulse and high-frequency circuits.
