When the resistance of the cable conductor does not meet the requirements, it will cause the cable to overheat during operation. When the voltage source is connected to the external load, it is considered that the internal resistance is in series with the external load. When using it, it is required that the internal resistance of the voltage source be as small as possible. When the voltage and material are the same, the better the material of the conductor, the lower the resistance. Power lines are generally made of copper coated aluminum or oxygen free copper. According to the resistivity of copper and aluminum wires: 1.At the same temperature, the resistivity of copper wire is 0.0175 Ω, while the resistivity of aluminum wire is 0.0294 Ω. The shorter the length of the power cord, the lower the resistance, and the larger the cross-sectional area, the lower the resistance. For most conductors, there is also a certain relationship with temperature. The higher the temperature, the greater the resistance, but for a few conductors, the resistance decreases with increasing temperature. 2. Local damage to the cable sheath can cause slow damage to the insulation performance after water ingress, resulting in a gradual decrease in insulation resistance and overheating during cable operation. During installation, the cables are arranged too densely, resulting in poor ventilation and heat dissipation. 4. The cable is too close to other heat sources, resulting in abnormal heat dissipation. 5. Poor joint manufacturing technology and loose crimping result in excessive contact resistance at the joint, leading to cable overheating. 6. Poor insulation performance between cables leads to low insulation resistance and overheating during operation.

Everyone is familiar with wires and cables, but do you know the difference between wires and cables?   The difference in materials Wire is a conductive metal wire used to carry electric current. Available in solid, twisted or foil braided forms. According to the insulation condition, they are divided into two categories: bare wires and insulated wires. A cable is an insulated wire consisting of one or more mutually insulated conductive cores placed in a sealed sheath. A protective covering layer can be added to the outside. The difference between wires and cables is that wires are generally smaller in size and simpler in structure, but sometimes cables are also classified as wires in a broad sense.   Differences in uses Bare wire is a wire that is not covered with any insulation or protective layer. In addition to being used as wires for transmitting electrical energy and information, it can also be used to manufacture components and connecting wires for motors and electrical appliances. Generally used are copper, aluminum, copper alloy, and aluminum alloy. In addition, there are various insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, electrical and motor lead wires, aviation wires, compensation wires, etc. Cables are used to transmit and distribute electrical energy or transmit electrical signals. Cables can be divided into power cables, communication cables and control cables according to their uses.   The difference in structure The main difference between power cables and ordinary wires is that the cables are larger in size and have a more complex structure. The cable is mainly composed of the following four parts. Conductive wire core: Made of high conductivity material. Insulating layer: The insulating material used as a cable should have high insulation resistance and high breakdown electric field strength. Cables are often classified by insulation materials. ​

Introduction: When it comes to buying computer cables, making the right choice is essential for ensuring optimal performance and reliability. This article provides a helpful guide to purchasing computer cables, outlining key factors to consider and tips to make the process easier.   Identify your Needs: Before purchasing computer cables, determine your specific requirements.

Understanding your needs will help you select the right type of cable.   Consider Cable Specifications: Pay attention to cable specifications such as length, cable gauge, connector type, and maximum data transfer speeds. Longer cables may experience signal degradation, and choosing the correct gauge ensures proper power delivery. The connector type should be compatible with your devices, and higher data transfer speeds may be important for certain applications.   Quality Matters: Opt for high-quality cables to maintain signal integrity and avoid interference. Look for cables with shielding to minimize electromagnetic interference, gold-plated connectors for better conductivity, and cables that meet industry standards. Investing in quality cables ensures a longer lifespan and better performance.   Read Reviews and Compare Prices: Before making a purchase, read reviews from reputable sources and compare prices. Consider the experiences of others to gauge the reliability and durability of the cables. Additionally, comparing prices across different sellers or online platforms can help you find the best deal without compromising quality.   Warranty and Return Policy: Check if the cables come with a warranty or return policy. This provides assurance in case of any defects or compatibility issues. A warrantied cable guarantees your investment, and a flexible return policy allows you to make changes if needed.   Conclusion: When purchasing computer cables, taking the time to identify your needs, considering cable specifications, prioritizing quality, reading reviews, comparing prices, and checking warranty and return policies are crucial steps. By following this guide, you can make an informed decision and ensure the purchase of reliable and compatible computer cables that will enhance your computing experience.
