But it is not possible to see through it from the surface. If you study the power cord carefully, you still need a professional understanding of the power cord structure in some places.
The structure of the power cord is mainly composed of an outer sheath, an inner sheath, and a conductor; common transmission conductors include copper and aluminum metal wires.
Outer sheath
The outer sheath is also called the protective sheath, which is the outermost layer of the power cord. This outer sheath plays a role in protecting the power cord. The outer sheath has powerful characteristics such as high temperature resistance, low temperature resistance, Anti-natural light interference, good winding performance, long service life, environmental protection of materials and other characteristics. Inner sheath: The inner sheath is also called an insulating sheath. It is an indispensable intermediate structural part of the power cord. As the name implies, the main insulation sheath is insulation to ensure the safety of the power cord and prevent the copper wire from being separated from the air. There will be any leakage phenomenon, and the material of the insulating sheath should be soft to ensure that it can be well embedded in the middle layer.
Copper wire
The copper wire is the core part of the power cord. The copper wire is mainly the carrier of current and voltage. The density of the copper wire directly affects the quality of the power cord. The material of the power cord is also an important factor for quality control, and the quantity and flexibility of the copper wire are also one of the factors to be considered.
Inner sheath
The inner sheath is a layer of material that wraps the cable between the shielding layer and the core, usually polyvinyl chloride plastic or polyethylene plastic. There are also low-smoke and halogen-free materials. Use in accordance with the process regulations, so that the insulating layer will not come into contact with water, air or other objects, to avoid moisture and the insulating layer from mechanical damage
