A plug power cord is a complete set of power supply connection wires that integrates national/international standard plugs and insulated cables. As a transmission carrier between electrical equipment and mains sockets, it integrates multiple functions such as conductivity, insulation, grounding, and mechanical protection. It is widely used in various low-voltage electrical products such as home appliances, office equipment, small industrial equipment, and digital devices, and is a basic supporting component to ensure stable power transmission and electrical safety. The entire wire set consists of four main parts: plug, sheath, insulated core, and outer sheath. The overall production strictly follows the electrical safety standards of various countries. The conductive pins of the plug are made of high conductivity copper alloy stamped and formed, with nickel plating on the surface for oxidation resistance. The contact resistance is small, and it is not easy to heat up or ignite when powered on for a long time; The shell is made of flame-retardant engineering plastic injection molding, with high insulation strength, impact resistance, and high temperature resistance, which can effectively isolate live parts and avoid electric shock hazards. The plug is equipped with a wire locking structure inside, which firmly fixes the cable and prevents the internal core from loosening or breaking when pulled or bent. The cable section is divided into two types based on the usage environment: plastic sheath and rubber sheath. Plastic cables often use PVC insulation layer, which is lightweight and suitable for indoor room temperature and dry scenarios; Rubber sheathed cables have stronger flexibility, are resistant to bending, wear, and low temperatures, and can be adapted to frequent dragging and use conditions such as electric tools and outdoor mobile equipment. The internal conductor is made of multi stranded oxygen free copper, with uniform conductivity and temperature rise control in accordance with standards. The wire core is divided into two core, three core and other specifications. The three core cable is equipped with an independent grounding core wire, and the metal shell can achieve leakage protection when used in high-power equipment. According to the adaptation standards, it includes various standards such as national standard 3C complete power cords, IEC appliance power cords, European standards, American standards, British standards, etc. Different standards are matched with local socket specifications, and the rated voltage and current are clearly divided, covering common specifications such as 6A, 10A, 16A, etc. It is suitable for different loads from small power adapters to high-power fans, refrigeration equipment, etc. The surface of the formal complete set of wire is printed with clear model, voltage, certification marks, and implementation standards. The entire product has passed the mandatory safety certification in the corresponding region. The finished product has stable comprehensive performance: the insulation layer meets the withstand voltage standard and is not prone to leakage; Resistant to aging and wear, long-term use without cracking or hardening; The plug insertion and removal force is balanced, and the contact is tight after insertion, without virtual connection heating. It can meet various working conditions such as indoor fixed use, equipment mobile operation, damp kitchen and bathroom, outdoor short-term power supply, etc. It also meets the needs of standardized batch matching and conventional equipment replacement, and is an indispensable safety supporting wire for various types of electrified equipment.
