From the outside to the inside, progressively analyze the structure of the power cable
I believe everyone is no stranger to power cords, because they are ubiquitous in our daily life, study and work. However, everyone's knowledge of the power cord may only stop at its basic functions, and they are often not very familiar with the basic design and structure of the product. work and study help.
1. The outer layer. The outer layer is the outermost part of the power cord, and it is also the part that the human body can directly touch. From the name, it is easy to see that its role is to play a protective role. Power transmission has certain requirements for the environment. High temperature, high pressure, low temperature, and more water will affect its normal transmission. At this time, a protective cover is needed to adjust the environment and avoid direct contact with the external environment to improve its environmental adaptability. , but also can effectively improve the service life of the product.
The second is the inner layer. The inner layer is also a protective device for the wire, the main purpose is to use the insulation properties of the product to prevent power leakage. As a protective device for the inner layer, the material cannot be too hard, and the copper wire can be well wrapped without leakage.
Third, copper wire. Copper wire is the core component of the power cord and the most important material for power transmission. The quality of its texture is directly related to the quality and use of the power cord.
