What is the composition of the AC power cord?
The structure of the AC power cord is notvery complicated, but not from the surface of the simple can see it all atonce, if the good to study the power cord, then some places still need tounderstand the structure of the AC power cord.
The structure of the AC power cord mainlyto the outer jacket, inner sheath, conductor, the common transmission conductorcopper, aluminum wire and so on.
The outer jacket is also known as theprotective sheath, is the outermost layer of the AC power cord, this layer ofouter jacket plays a protective AC power cord role, the outer jacket has a strongfeature, 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 AC powercord indispensable part of the middle structure, insulation sheath with thename suggests is insulation, to ensure that the power cord is safe, so thatbetween the copper and air Will produce any leakage phenomenon, and theinsulation sheath of the material to be soft, to ensure a good fit in themiddle layer.
Copper wire is the core of the AC powercord, copper wire is mainly the current and voltage of the carrier, the copperwire density directly affects the quality of the power cord. AC Power cordmaterial is also an important factor in the quality of checks, the number ofcopper and flexibility is also considered one of the factors.
The inner sheath is a layer of materialthat wraps the cable between the shield and the core, usually of polyvinylchloride or polyethylene. There are also low smoke halogen-free material. Inaccordance with the provisions of the use of technology, so that the insulationwill not contact with water, air or other objects, to avoid insulation andinsulation of the insulation layer from mechanical damage.
