Practical application and working principle of stainless steel braided casing

Stainless steel braided sleeves are used in computer power lines, speaker monitoring video lines, cables and wires, etc., to play a protective role. In almost any electronic circuit, the Stainless Steel braided sleeve of semiconductor material is required. It plays a vital role in many power circuits. It is one of the earliest semiconductor components, and its application is also very common.

The principle of the metal material Stainless Steel Braided Sleeve is that the crystalline stainless steel Braided Sleeve is a p-n junction produced by a p-type semiconductor and an n-type semiconductor, and a space charge layer is generated on both sides of the page, and an electric field is built. When there is no additional voltage, because the creep current caused by the difference in free electron concentration on both sides of the p-n junction is the same as the drift current caused by the construction electric field, it is in a state of electrical balance. When there is a positive voltage bias externally, the mutual suppression effect of the external electric field and the built-in electric field increases the creeping current of free electrons to form a positive current.
When there is a reverse voltage bias externally, the external electric field and the built-up electric field are further strengthened, resulting in a reverse saturation state current I0 that is irrelevant to the reverse bias voltage value within the reverse voltage range. When the additional reverse voltage is high When the level is reached, the electric field strength in the p-n junction space charge layer reaches the critical point, resulting in the growth process of free electrons, forming a large number of electron-hole pairs, and generating a very large reverse penetration current, which is called It is the penetration status of stainless steel braided casing.
The positive pole of the stainless steel braided sleeve in the electronic circuit is connected to the low potential difference end, and the negative pole is connected to the high potential end. At this time, there is almost no current passing through the stainless steel braided sleeve. At this time, the stainless steel braided sleeve is in the cut-off state. The class interface method is called reverse bias. When the stainless steel braided bushing is in reverse bias, there is still a weak reverse current passing through the stainless steel braided bushing, which is called leakage current. When the reverse voltage on both sides of the stainless steel braided sleeve increases to a certain value, the reverse current will greatly increase, and the stainless steel braided sleeve will lose its unidirectional conductivity. This situation is called the penetration of the stainless steel braided sleeve. .
Stainless steel braided casing products are made of stainless steel, which has the advantages of high impact toughness, strong pressure resistance, electrical flame retardancy, and wide application temperature range (-40°C-500°C). This kind of cable protection material is widely used in drainage pipes, natural gas, electric power engineering, transmission pipes, water pipes, water supply pipes, drainage pipes and other pipes in the iron and steel industry circulation system, textile industry, printing and dyeing factory, paper industry: transportation of materials Processing process pipeline discharge pipe.
Therefore, in daily life, cable protection sleeves are also necessary in daily life. If you want to give yourself more protection, consider daily life and physical and mental health, and give yourself two layers of protection. I believe that in the future life, the Cable Protection Sleeve is an indispensable daily necessities.
