The power cord is a common product in people's daily life, and it is one of the basic facilities for the entire life and production. If there is no power cord, people's lives and production will fall into darkness. The role of the power cord is very large. In addition to the production of conductors, what are the requirements of the power cord manufacturer for the material of the outer sheath?

　　 One, high and low temperature resistance

　　 In the heavy snow disaster in 2008, people saw the impact of snow on outdoor power lines. Because the snow has frozen the power cord, power outages have occurred in various disaster areas. From this phenomenon, we can see the influence of temperature on the power cord. Therefore, when making the outer sheath, Tag Heuer Formula 1 Replica must choose materials with high and low temperature resistance.

　　 2. Good winding performance

　　 The arrangement of the power cords is not all straight. Some power cords must be bent and installed. For the sake of beauty, some families will wrap the power cords together and embed them in various gaps. This requires the power cord to have a better winding performance so that it can be wound together.

　　 3. Long service life

　　 The outer sheath of the power cord also has an extremely long service life. If its use time is relatively short, it will affect people's normal life and production. Long-term use can effectively prevent various problems during use, and the power cord will not be updated due to the aging of the outer sheath.

　　 Fourth, materials should be environmentally friendly

　　Environmental protection is a theme of social development. The outer sheath material of the power cord is no exception. Manufacturers should use more environmentally friendly materials to prevent environmental pollution.

　　 The above four points are the performance that the outer sheath must have. If one of them is missing, it will have some adverse effects on the outer sheath, thereby affecting the use of the entire product.
