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 shall have good resistance to high and low temperature. Summer and winter are two extreme seasons. In the world, the temperature difference between different regions is also very large. For example, in Africa, the temperature is too high for ordinary people. Therefore, the power cord sold to Africa must have very high resistance to high temperature. Another example is the northern part of our country, the temperature in winter is dozens of degrees different from the south
Therefore, the power cord used in those places with more than ten degrees below zero in winter must have good low temperature resistance.
The outer sheath material of the second plug line must be environmentally friendly. Environmental protection is the first priority. If environmental protection materials are used for industrial power line outer sheath, it will not pollute the environment. Therefore, power line manufacturers must use environmental protection sheath materials.
The service life of the outer sheath of the third plug line 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, it will avoid the problem of frequently replacing the power cord, and the power cord will not have such problems due to the aging of the outer sheath. The outer sheath of the power line plays a role in protecting the inner core, so it is necessary to understand the performance of the outer sheath of the power line.
