Industrial robots' wires can be classified into the following five categories based on their functions and application locations: Power cables: Provide power to the robot body and need to withstand large current transmission. They are usually fixedly laid and require high wear resistance and high-temperature resistance. Control cables: Transmit control signals to ensure precise movements of each joint of the robot. They need to have anti-interference capabilities and low latency characteristics. Signal cables: Used for feedback of sensor data, such as position, temperature, and pressure, and require stable signal transmission and resistance to electromagnetic interference. Network communication cables: Support data exchange between the robot and external systems (such as PLC, upper computer). Common types include Ethernet cables.

1. PVC sheath: The surface shows a regular "unevenness" caused by the compression of the inner braided net, indicating good processing quality and no relative sliding, which is a good cable; if the sheath is smooth without any "unevenness" caused by the compression of the braided net, and there is a sense of looseness when the sheath is pinched with your hand, it is a poor cable. 2. Check the braided net of the shielding layer: Check if the number of braids is sufficient. For copper braided nets, check the weldability. Scrutinize the soldered area to see if there is copper wire inside. The hardness of aluminum-magnesium alloy wires is significantly greater than that of copper wires; if the braiding is sparse, unevenly distributed, and not tightly wrapped around the insulation layer, etc., it is a poor cable. 3. Check the core wires: Diameter - For SYV cables, it is 0.78 to 0.8mm; for SYWV cables, it is 0.8 to 0.9mm.

The power industry has long been a pillar industry in China, occupying a significant position in the national economy. With the rapid economic development of China since the 1990s, the wire and cable manufacturing industry, as an important link in the power industry's industrial chain, has also flourished. Especially in recent years, as China has faced bottlenecks in energy and power supply due to economic growth, the state has continuously increased investment in the power sector, leading this industry into a period of rapid development. In the long term, there has been a phenomenon in China's power industry of "emphasizing power sources while neglecting the power grid", with the ratio of power sources to power grids being 7:3, while in developed countries, this ratio is basically 5:5. Consequently,

In order to reduce the environmental impact of motor vehicles and meet the requirements of fuel economy and carbon dioxide emission regulations, the promotion of hybrid and electric vehicles is a good choice for automobile manufacturers. In the coming years, the global demand for these alternative energy vehicles will continue to increase. However, while electric vehicles bring environmental benefits, they also have their own shortcomings. How to shield the electromagnetic waves generated during the high-voltage operation of electric vehicles, as well as the interference of the electric vehicle wiring, the sealing performance of the wiring and connectors. Therefore, when designing and developing hybrid and electric vehicles, these problems need to be solved; otherwise, it will lead to...

1. Check the certification mark. Products that have obtained mandatory certification must have the certification mark, namely the "CCC" mark, affixed to a prominent position on the product. Otherwise, it is considered an un-certified product. 2. Examine the inspection report. Electrical wires and cables are products that affect personal and property safety and have always been a key area of government supervision. Regular manufacturers undergo periodic inspections by the supervisory department. Therefore, sellers should be able to provide inspection reports from the quality inspection department. Otherwise, there will be no basis for judging the quality of the product. 3. Test insulation and sheath. The thickness of the insulation and sheath should be uniform without any skewness. When touched, there should be obvious tension and elongation. At the same time, the surface of the insulation and sheath should be...
