What does a power cord consist of
The power cord is mainly composed of three layers
A outer sheath
Outer sheath is also known as protective sheath, is the outermost sheath of power line, this layer of outer sheath plays a role in protecting the power line, outer sheath has powerful characteristics, such as high temperature resistance, low temperature resistance, resistance to natural light interference, good performance, high service life, material environmental protection and other characteristics.
B in the sheath
The inner sheath, also known as insulation sheath, is a layer of material wrapped between the shielding layer and the cable core, usually PVC plastic or polyethylene plastic. Is an indispensable part of the middle structure of the power line, the main use of insulation sheath, as the name implies, is insulation, to ensure the power of the power line safety, so that there will not be any leakage phenomenon between the copper wire and the air, and the material of the insulation sheath is soft, to ensure that it can be inserted in the middle layer.
C conductor
Common transmission conductors are copper, aluminum metal wire, etc. The conductor of our power cord is usually copper wire. Copper wire is mainly the carrier of current and voltage, the density of copper wire directly affects the quality of the power line. The material of the power line is also an important factor in quality control, as is the quantity and flexibility of the copper wire.
