The composition of the AC power cord
AC power cord composition
The structure of the AC power cord is not very complicated, but not from the surface of the simple can see through it at once, if the good to study the AC power cord, then some places still need to understand the structure of the AC power cord.
The structure of the AC power cord mainly to the outer jacket, inner sheath, conductor, the common transmission conductor copper, aluminum wire and other metal.
The outer jacket is also known as the protective sheath, is the outermost layer of the power cord jacket, this layer of outer jacket plays a protective power line role, the outer jacket has a strong feature, such as high temperature, Anti-natural light interference, winding performance, high life, environmental protection and other characteristics of materials. Inner sheath: inner sheath, also known as the insulation jacket, is the power cord indispensable part of the middle structure, insulation sheath with the name of the insulation is to ensure that the power cord power security, so that between the copper and air Will produce any leakage phenomenon, and the insulation sheath of the material to be soft, to ensure a good fit in the middle layer.
Copper wire is the core of the power cord, copper wire is mainly the current and voltage of the carrier, the copper wire density directly affects the quality of the power cord. Power cord material is also an important factor in the quality of checks, the number of copper and flexibility is also considered one of the factors.
The inner sheath is a layer of material that wraps the cable between the shield and the core, usually of polyvinyl chloride or polyethylene. There are low smoke halogen-free material. In accordance with the provisions of the use of technology, so that the insulation will not contact with water, air or other objects, to avoid insulation and insulation of the insulation from mechanical damage.
