Correct Selection of Copper Wires and Cables
Behind the rapid development and expansion of the automotive field in recent years, there is a strong and powerful "guard", which is the cable and power supply system. For automobile manufacturers, the power supply system is the "foundation" for maintaining the normal operation of a huge automobile manufacturing plant. According to the Associated Press, a factory of a famous French car manufacturer suffered a power outage of only a few hours in 2014, which caused damage to the production of hundreds of cars, exceeding the company's initial estimate.
Accompanied by the continuous improvement of the intelligent level of automobile manufacturing plants. The demand for power quality of power engineering electronic components such as variable frequency speed regulators and smart robots commonly used in automation technology production lines is also becoming higher and higher. Power stability issues, including sags in working voltage, will cause non-planned shutdowns of the factory, machine equipment server downtime, major equipment destruction, commodity damage and other property losses. According to an investigation report of the American Academy of Electric Power, the average loss of car production due to power quality problems is $300,000. The power quality problem has become one of the main factors for automakers to maintain high-efficiency manufacturing.
As a cable medium to transport electrical energy, the reliability and stability of the cable power supply system is also necessary in the automobile factory. The safe and stable cable power supply system carries out power transmission and distribution at the required working voltage level. In the specific transmission and distribution links, the higher resistance of the cable material will cause more serious current damage. As a result, the current at the working voltage deviates from the working voltage level required by the power supply system, thereby accelerating the destruction and embrittlement of the facility. In severe cases, the equipment will be destroyed immediately, causing the equipment to shut down. For automobile manufacturers, a safe and stable power supply system is the main prerequisite for them to maintain the operation of complex power distribution equipment to ensure that all production and manufacturing are carried out normally 24 hours a day.
How to ensure the safety and stability of the power supply system? It is a key way to improve the route of the power supply system, including the use of copper cables with lower resistance and higher conductivity.
Among the many cables, copper cables have undoubtedly become the best choice. Why do copper cables have unique characteristics? There are three key factors:
1. The conductivity of copper is very high, about 1.57 times that of aluminum. The high-quality electrical conductivity of copper can make the cable less likely to encounter heat, ensuring the safety protection, environmental protection and energy saving of the power supply system.
2. Compared with cross-sectional copper cables and aluminum cables, copper cables have higher cable current carrying capacity, lower operating voltage loss and lower equipment failure rate. It can achieve the huge energy supply of automobile manufacturers and establish a key foundation for ensuring the uninterrupted operation of machinery and equipment.
3. Copper has strong heat resistance. Even if copper is oxidized by air, the converted copper chloride is still a high-quality electrical conductor, which can ensure the electrical connection characteristics of the connector and the terminal. The iron oxide formed after aluminum is oxidized by air is an insulator, which will harm the electrical conductivity of the connector or terminal, and aggravate the hot of the connector or terminal, which will cause cable fault testing and even fire accidents.
In addition, copper cables also have excellent heat resistance characteristics. The melting temperature of aluminum is 660°C, while copper can reach 1080°C. Even under continuous high temperature conditions, copper cables can still maintain the function of conducting electricity, which provides a key guarantee for the safe use of electricity for automobile manufacturers.
It is worth mentioning that copper cables can not only ensure the safe use of electricity for car manufacturers, but also complete the concept of sustainable development for them. Copper is a very typical "environmentally friendly" metal material, which can be 100% recycled. Indirectly, copper cables are more in line with environmental protection, and thus better promote the concept of sustainable development in the power supply field.
