In addition to the core components, the power cord also has a structure composed of inner and outer sheaths. The outer and inner sleeve is the outermost layer of the entire power cord, which can be seen and touched by people and exposed to the air. So what kind of temperature resistance does the power cord have for the material of the outer sheath?

　　1. High temperature resistance

　　High temperature resistance is an important feature. This is mainly due to the different requirements of the environment caused by the power cord. Rolex Submariner Replica Some power cords are used outdoors. In summer, the temperature will be very high. If there is no good high temperature resistance, then the outer sheath of the power cord will become fragile and cannot load current. .

　　 In addition to the high temperature of the weather, some occasions caused by the power cord are related to the high temperature. At present, there are many high-temperature operation projects in my country. Therefore, the power cord of the machine operating at high temperature needs high temperature resistance, otherwise it will easily cause the reduction of the service life of the machine.

　　 2. Low temperature resistance

　　 In addition to high temperature resistance, the material of the outer sheath must also have good low temperature resistance. This is actually the same as high temperature resistance. Just like every winter, the temperature in the high latitudes of our country is very low, and even in winter, it will freeze and snow outdoors. The power cord must have good low temperature resistance in such an environment. Otherwise, once the power cord freezes outdoors, it will greatly affect the use of the entire cord. If there is no good low temperature resistance, it will accelerate the aging of the power cord, making it unable to work normally for a long time.

　　Only with both high temperature resistance and low temperature resistance can the power cord withstand the harsh environment such as scorching sun and heavy snow, and the power cord can be used effectively for a long time.
