Application and principle of PP Self Wrap Braided Sleeve

PP Self Wrap Braided Sleeve are used in computer power lines, audio and video lines, wires and cables and other industries for protection. In almost all electronic circuits, semiconductor PP Self wrap braided sleeve are used, and it plays an important role in many circuits. It is one of the earliest semiconductor devices, and its application is also very extensive.

The working principle of the metalPP Self Wrap Braided Sleeve, the crystal Pp Self Wrap Braided Sleeve is a p-n junction formed by a p-type semiconductor and an n-type semiconductor, and a space charge layer is formed on both sides of the interface, and a self-built electric field is built. When there is no external voltage, the diffusion current caused by the carrier concentration difference on both sides of the p-n junction is equal to the drift current caused by the self-built electric field, and it is in a state of electrical balance. When the outside world has a forward voltage bias, the mutual suppression of the external electric field and the self-built electric field increases the diffusion current of the carriers and causes a forward current. When there is a reverse voltage bias in the outside world, the external electric field and the self-built electric field are further strengthened, forming a reverse saturation current I0 within the reverse voltage range that has nothing to do with the reverse bias voltage value. When the external reverse voltage reaches a high level , the electric field strength in the p-n junction space charge layer reaches a critical value to generate a multiplication process of carriers, a large number of electron-hole pairs occur, and a large reverse breakdown current occurs, which is called the breakdown of PP Self Wrap Braided Sleeve. wearing phenomenon.
In the electronic circuit, the positive pole of the PP Self Wrap Braided Sleeve is connected to the low potential end, and the negative pole is connected to the high potential end. At this time, there is almost no current flowing in thePP Self Wrap Braided Sleeve, and the PP Self Wrap Braided Sleeve is in the cut-off state. , this connection is called reverse bias. When thePP Self Wrap Braided Sleeve is in reverse bias, there will still be a weak reverse current flowing through the PP Self Wrap Braided Sleeve, which is called leakage current. When the reverse voltage at both ends of the PP Self Wrap Braided Sleeve increases to a certain value, the reverse current will increase sharply, and the PP Self Wrap Braided Sleeve will lose its unidirectional conductivity. This state is called PP Self Wrap Braided Sleeve breakdown.
PP Self Wrap Braided Sleeve products are made of steel, with high mechanical strength, strong pressure bearing capacity, electrical insulation performance, and wide operating temperature range. For example, Huidian brand cable fireproof pipes, these cable protection materials are widely used in drainage, gas, electric power, transmission pipelines, steel industry circulating water pipes, water transmission, drainage pipes and other pipelines, textile, printing and dyeing, paper industry: transmission medium Process piping discharge pipe.
Therefore, in life, cable protection sleeves are also needed in life. If you want to provide more guarantees for yourself, for the sake of life and health, you must provide double protection for yourself. I am more convinced that in the future life, the Cable Protection Sleeve is an indispensable daily necessities.
