Power cord is one of the indispensable accessories in electronic products, which is a kind of cable connecting the output of power supply with the input of electronic equipment. With the popularization of electronic products and the expanding range of applications, there are more and more types of power cords. In order to ensure the safety and reliability of power cords, a series of international standards for power cords have been developed, including specifications, classification and application. Let's learn about them one by one below.
Power cord specifications
The specifications of the power cord mainly refer to the wire diameter, length, color and other aspects. Commonly used power cord wire diameter 0.5mm2, 0.75mm2, 1.0mm2, 1.5mm2, 2.5mm2, etc., the length is usually 1 meter, 1.5 meters, 2 meters, 3 meters, 5 meters, etc.. In terms of color, the common ones are black, white, gray, red, yellow, blue and so on. When buying power cords, you need to choose the appropriate specifications according to your needs to ensure the stability and safety of the power cord.
Power cord classification
Power cords can be categorized into AC power cords and DC power cords according to their different uses. AC power cord is generally used for household appliances, televisions, computers and other equipment, which is characterized by high voltage, low frequency, need to have to prevent leakage, fire and other safety features. DC power cord is mainly used for LED lights, surveillance cameras, power tools and other equipment, which is characterized by low voltage, high frequency, need to have anti-electromagnetic interference, anti-static and other properties.
Power cord applications
Power cords have a wide range of applications, covering almost all electronic devices. In the home, power cords are mainly used to power TVs, computers, stereos, lamps and other equipment. In the industrial field, power cords are used to power machines, power tools, electronic components and other equipment. In the medical field, power cords are used to power medical equipment, operating tables and other devices. In the field of transportation, power cords are used to power transportation facilities such as subways and high-speed railways.
Purchase of power cord considerations
1. Selection of specifications: According to the power and voltage requirements of the equipment to select the appropriate power cord specifications to ensure the stability and safety of the power cord.
2. Quality inspection: When buying power cords, you need to carefully check whether the appearance of the power cord is intact, whether there are breaks, cracks and other defects, but also need to check whether the conductivity of the power cord is good.
3. Brand selection: When buying power cords, you can choose some well-known brands of products to ensure the quality and stability of the power cord.
4. Safety performance: When buying power cords, you need to pay attention to the safety performance of the power cord, such as whether it has the function of anti-leakage and fire prevention.
