The primary uses of power cords

　　In the realm of household appliances: These devices—such as refrigerators, televisions, washing machines, air conditioners, microwave ovens, rice cookers, and more—are powered via power cords connected to the home’s electrical system, ensuring a steady supply of electricity for their proper operation. For instance, the refrigerator’s power cord channels external mains electricity into its internal circuitry, enabling components like the compressor and lighting system to function; meanwhile, the TV’s power cord supplies energy to essential modules, including the display screen and audio output systems.

　　In the field of electronic devices: Devices such as computer hosts, monitors, printers, scanners, routers, and more rely on power cords to receive electricity. A computer's power cord not only supplies power to the motherboard, CPU, hard drive, and other hardware components of the host but also provides electricity to the monitor, ensuring that the entire computer system operates smoothly. Meanwhile, although a router's power cord is relatively thin, it delivers the essential electrical support needed for the router's functions—such as transmitting network signals and processing data—thereby maintaining a stable internet connection.

　　In the industrial equipment sector: In factory and industrial production environments, various large-scale machinery, automated production lines, industrial robots, and more rely on power cables to deliver robust electrical energy. For instance, the power cables for CNC machine tools must carry substantial currents, supplying stable electricity to the machine's motors, control systems, and other components—ensuring precise machining performance and operational efficiency. Similarly, devices such as sensors and actuators along industrial automation assembly lines are connected to control systems via power cables, enabling seamless, automated operations.

　　In the field of lighting, whether it's indoor lighting fixtures—such as chandeliers, wall lamps, table lamps, and more—or outdoor lighting installations like streetlights and landscape lights, all require power cables to transmit electrical energy. In indoor settings, power cables distribute electricity to individual灯具, creating a comfortable and inviting lighting environment for people. Meanwhile, in outdoor applications, streetlight power cables are responsible for delivering electricity from the power supply system directly to the fixtures mounted on streetlight poles, ensuring safe and reliable illumination of roads during nighttime hours.

　　In the medical equipment field: Many medical devices—such as electrocardiographs, patient monitors, X-ray machines, and ultrasound diagnostic systems—require extremely high levels of power stability and safety. The role of power cords is to deliver clean, stable electricity to these sophisticated medical instruments, ensuring their proper operation and the accuracy of diagnostic results, which directly impacts the effectiveness of medical diagnosis and treatment.

　　In the automotive and transportation sectors: Inside vehicles, power cables are used to connect the car battery to various components such as the engine, dashboard, headlights, audio systems, and electric seats, supplying them with electricity. Additionally, charging cables for electric vehicles are a specialized type of power cable, designed to transfer electrical energy from an external power source into the vehicle's battery, enabling battery charging. In the transportation sector—such as electric buses and electric bicycles—power cables also play a critical role in facilitating essential electrical power transmission.

　　In the telecommunications sector: A large number of servers, switches, communication equipment, and other devices in telecom infrastructure such as base stations and data centers require a stable power supply. Power cables bring in mains electricity or other power sources to these facilities, providing the energy needed for equipment operation—and ensuring the seamless functioning of communication networks and the reliable transmission of data.
