Power cord structure

The structure of the power cord is not very complicated, but it is not easy to see through it from the surface. If you study the power cord well, some places need to know the structure of the power cord professionally.

The structure of the power cord mainly requires an outer sheath, an inner sheath, and a conductor, and a common transmission conductor has a wire made of copper or aluminum.

Outer Sheath: The outer sheath is also called the protective sheath. It is the outermost layer of the power cord. This outer sheath serves to protect the power cord. The outer sheath has strong characteristics, such as high temperature resistance. It is resistant to low temperature, natural light interference, good winding performance, high service life and environmentally friendly materials.

The inner sheath of the power cord: the inner sheath is also called the insulating sheath, which is an indispensable intermediate structure part of the power cord. The main purpose of the insulating sheath is the insulation, which ensures the power supply of the power cord is safe, so that the copper wire and the air are directly There will be no leakage, and the material of the insulating sheath should be soft to ensure that it is well embedded in the middle layer.

Copper wire: The copper wire is the core part of the power wire. The copper wire is mainly the carrier of current and voltage. The density of the copper wire directly affects the quality of the power wire. The material of the power cord is also an important factor in the quality control. The number and flexibility of the copper wire are also considered factors.
