What kind of performance does the outer sheath of the power cord have to make it the outer sheath of the plug wire?
The outer sheath of the first plug wire should have good resistance to high and low temperatures. Summer and winter are two extreme seasons. In the world, the temperature difference between different regions is also very large. For example, in Africa, where the temperature is unbearable for ordinary people, the power cords sold to Africa must have very high-temperature resistance. Another example is the northern part of our country, the temperature in winter is tens of degrees different from that in the south, so the power cord used in those places where the temperature is minus ten degrees or twenty degrees in winter must have good low-temperature resistance.
Second, the outer sheath material of the plug wire must be environmentally friendly. Environmental protection is the first priority. The outer sheath of power cords used in the industry uses environmentally friendly materials to prevent pollution to the environment. Therefore, power cord manufacturers must use environmentally friendly outer sheath materials.
The service life of the outer sheath of the third plug wire should not be too short. If the service life of the outer sheath of the power cord is too short, it will affect people's daily life and production. If it is used for a long time, some problems of frequent replacement of the power cord will be avoided, and the power cord will not be aged due to the aging of the outer sheath. And there are such problems. The outer sheath of the power cord protects the inner core, so it is necessary to understand the performance of the outer sheath of the power cord.
