The power cord is the wire that transmits the current, and the copper wire is the core of the power cord. Usually the way the current is transmitted is point-to-point transmission. Power lines in accordance with the use can be divided into AC AC power lines and DC DC power lines, AC power cord is usually through the higher voltage AC wire, this type of wire due to the need for uniform high voltage standard safety certification can be formally produced. The DC line is basically through the lower voltage of the DC, Power Cord so the safety requirements and no AC line strict, but for safety reasons, the current countries or require uniform security certification.

The structure of the power cord is not very complicated,

But not from the surface can simply see through it at once, if the good to study the power cord, then some places still need to understand the professional structure of the power cord.

The structure of the power cord mainly to the outer jacket, inner sheath, conductor, Power Cord the common transmission conductor copper, aluminum wire and other metal.

Outer jacket

The outer jacket is also known as the protective sheath, is the outermost layer of the power cord, 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, Power Cord is an indispensable part of the power cord, the insulation sheath of the main name is insulated, to ensure that the power cord safety, 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

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 line material is also an important factor in quality checks, the number of copper and flexibility is also considered one of the factors.

Inner sheath

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. Power Cord In accordance with the provisions of the use of technology, so that the insulation will not be in contact with water, air or other objects, to avoid insulation moisture and insulation from mechanical damage.
