A power cord is a wire that carries electric current. The usual way of current transmission is point-to-point transmission. Power cord according to the use can be divided into Ac Power Cord and DC power cord, usually AC power cord is through the higher voltage AC wire, this type of wire due to the higher voltage need to unify the standards to obtain safety certification before official production. The DC line is basically through the lower voltage DC, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification.Retrofitting Wire Harness

The structure of the power cord is not very complex, but do not simply from the surface can be seen through it at once, if you study the power cord, there are places that still need to be professional to understand the structure of the power cord.
Power cord structure mainly to the outer sheath, inner sheath, conductor, common transmission conductors are copper, aluminum wire, etc.Motherboard Connector
Outer sheath
Outer sheath, also known as the protective sheath, is the outermost layer of the power cord sheath, the outer sheath plays a role in protecting the power cord, the outer sheath has strong characteristics, such as high temperature, low temperature, resistance to natural light interference, good winding performance, high service life, environmentally friendly materials and other characteristics.
Inner sheath
The inner sheath, also known as the insulation sheath, is an indispensable part of the middle structure of the power cord, the main use of the insulation sheath is, as the name implies, insulation to ensure the safety of the power cord, so that no leakage between the copper wire and air, and the insulation sheath material to be soft, to ensure that it can be well set in the middle layer.
Copper wire
Copper wire is the core part of the power cord, copper wire is mainly a carrier of current and voltage, the density of copper wire size directly affects the quality of the power cord. The material of the power cord is also an important factor in quality control, and the quantity and flexibility of the copper wire is one of the factors to be considered.Atmosphere light wiring harness
Inner sheath
The inner sheath, a layer of material wrapped around the cable between the shield and the core, is generally PVC plastic or polyethylene plastic. Low smoke and halogen-free materials are also available. It is used in accordance with the process regulations so that the insulation will not come into contact with water, air or other objects, to avoid moisture in the insulation and to protect the insulation from mechanical damage.
