The structure of the power cord assembly is not very complicated, but it should not be seen from the outside for a while. If you want to study the power cord well, some locals still need to know the structure of the power cord professionally.
The structure of the power cord is mainly an outer sheath, an inner sheath, and a conductor. A common transmission conductor has a wire of copper or aluminum material.
Outer sheath
The outer sheath is also called the maintenance sheath. It is the outermost layer of the power cord. This outer sheath acts as a maintenance power cord. The outer sheath has strong characteristics, such as high temperature resistance and low temperature resistance. It is resistant to natural light disturbance, good winding performance, high service life and environmental protection. Inner sheath: The inner sheath is also called the insulating sheath. It is the central structure part of the power cord. The main purpose of the insulating sheath is insulation. Ensure the power supply is safe, so that there is no copper wire or air. Any leakage will occur and the insulation sheath material should be soft to ensure that it is well embedded in the center layer.
Copper wire
The copper wire is the central part of the power line. The copper wire is primarily the carrier of current and voltage. The density of the copper wire directly affects the quality of the power line. The data of the power cord components is also an important factor in the quality control. The quantity and flexibility of the copper wire are also considered as one of the factors.
Inner sheath
The inner sheath is a layer of information about the wrapped cable between the shield and the core, typically polyvinyl chloride plastic or polyethylene plastic. There are also low-smoke halogen-free materials. According to the rules of the process, the insulation layer will not touch water, air or other objects.
