The structure of the power cord mainly requires an outer sheath, an inner sheath, and a conductor. Common transmission conductors include copper and aluminum wires.
1. 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 and low-temperature resistance. Anti-natural light interference, good winding performance, high service life, and environmentally friendly materials.
2. Inner sheath
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 to insulate, to ensure the power supply safety of the power cord so that no leakage occurs between the copper wire and the air. Phenomenon and the material of the insulating sheath should be soft and ensure that it is well embedded in the middle layer.
3. Copper wire
The copper wire is the core part of the power line. The copper wire is mainly the carrier of current and voltage. The density of the copper wire directly affects the quality of the power line. The material of the power cord is also an important factor in quality control. The number and flexibility of the copper wire are also considered factors.
4. Inner sheath
The inner sheath is a layer of material that wraps the cable between the shield and the core, typically polyvinyl chloride plastic or polyethylene plastic. There are also low-smoke halogen-free materials. Use according to the process regulations, so that the insulation layer will not come into contact with water, air or other objects, and the insulation will be protected from moisture and the insulation layer will be protected from mechanical damage.
The connector of the general electronic product and the pin of the electrical appliance are called plugs. Household AC power plugs and sockets, with male or female connectors that are rod-shaped or copper-plated, physically plugged into female socket-type power outlets with slots or recesses. Dimens...
