Power cords are wires that carry electricity. Usually the way of current transmission is point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their usage. 一般的に, the AC power cord is a wire through which high voltage alternating current is passed. Due to the high voltage, this kind of wire can be formally produced only after obtaining safety certification under unified standards. The DC line basically passes direct current with a lower voltage, so the safety requirements are not as strict as the AC line, but for safety reasons, each country still has a unified safety certification.

The structure of the outdoor power cord
The structure of the power cord is not very complicated, but don’t simply see through it from the surface. If you study the power cord well, in some places, you still need a professional to understand the structure of the power cord.
The structure of the power cord mainly includes an outer sheath, an inner sheath, and a conductor. Common transmission conductors include metal wires made of copper and aluminum.

Outer sheath for outdoor power cord
The outer sheath, also known as the protective sheath, is the outermost sheath of the power cord. This outer sheath protects the power cord. The outer sheath has strong characteristics, such as high temperature resistance, low temperature resistance, natural light interference resistance, good winding performance, 長寿命, and environmentally friendly materials.

Inner sheath for outdoor power cord
The inner sheath, also known as the insulating sheath, is an indispensable middle structural part of the power cord. The main function of the insulating sheath, as the name implies, is to insulate, to ensure the safety of the power line, so that there will be no leakage between the copper wire and the air. And the material of the insulating sheath should be soft to ensure that it can be well embedded in the middle layer.

copper wire for outdoor power cord
The copper wire is the core part of the power cord, and the copper wire is mainly the carrier of current and voltage. The density of copper wire directly affects the quality of the power cord. The material of the power cord is also an important factor in the quality control, and the quantity and flexibility of the copper wire are also one of the factors considered.

Inner sheath for outdoor power cord
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 according to the process regulations, so that the insulation layer will not be in contact with water, air or other objects, and the insulation will be protected from moisture and mechanical damage.
