What are the main power cord colors? What are the application areas of power cords characteristic features functions?

The colors of power cords are mainly regulated by the International Electrotechnical Commission (IEC) and national standards. The following are some common power cord colors and what they represent: 1. Black: commonly used in alternating current (AC) power cables, representing the fire line (Live) or phase line. 2. White or gray: usually represents the neutral line (Neutral). 3. Green or green and yellow: represents the ground line (Ground) or the protection line. 4. It should be noted that different regions and may have slightly different regulations on the color of the power cord. Therefore, when using power cords, it is better to refer to the local electrical standards and regulations. Power cords are widely used in various fields and industries with the following features, characteristics and functions: 1. Power transmission: power cords are mainly used to transmit electrical energy from a power source to a device or system to supply it with the required power. It is capable of withstanding specific currents and voltages to ensure reliable power transmission.2. Safety and protection: Power cords usually come with a protective layer or sheath, which is used to provide insulation and protection to ensure personal safety and normal operation of equipment. The protective coating reduces the risk of electric shock and provides a degree of fire protection and shielding.3. Marking and identification: The color coding of power cords can be used to mark and identify different types of cords and cables. This aids in identification and differentiation during installation, maintenance and troubleshooting.4. Environmental Adaptability: Power cords need to be adapted to different environmental conditions and workplaces. For example, some power cords are resistant to high temperature, humidity, oil or corrosion to adapt to harsh working environments.5. Electromagnetic interference suppression: Some power cords come with shielding or insulation to suppress the effects of electromagnetic interference and ensure stable signal transmission. This is especially important in applications that require high-quality signals, such as audio, video, and data transmission.6. Reliability and Durability: Power cords need to have good reliability and durability to meet the challenges of long-term use and various external stresses. Good manufacturing quality, proper material selection and strict quality control can ensure the stability and durability of power cords.7. Compliance and Certification: Power cords usually need to comply with relevant international and industry standards, such as IEC standards and safety certification requirements. This ensures the safety, reliability and compatibility of power cords to meet market requirements. In summary, power cords play an important role in various industries and applications as a key component of power transmission. Its color coding and characteristics can ensure the reliable transmission of power and safe operation of equipment to meet the needs of different fields.
