　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.After screening and investigation shielded twisted pair cable It is likely to become a new force driving economic development. https://www.linkcablecn.com

　　Is it better to have a multi-core cable or a single-core cable?

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　The difference between single-core cables and multi-core cables

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　Multicore Flexible Cable supplier.jpg

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.

　　In the daily production of metal medals, there will be many details to be carefully improved. In addition to the main big things, it is also necessary to strengthen the attention to local details. For example, what style of medal wooden tray and what kind of medal back plate to match it should not be underestimated.

　　8. Clean layout of medals

　　I believe no one will like the colorful medal layout. Clean here does not mean dirty, but mainly refers to chaos and disorder.

　　9. The price of medal production

　　One cent for one product has always been the value law of any industry and any commodity. It is now difficult to obtain high-end products at a very low price.

　　10. The medal is beautifully packaged

　　The packaging of metal medals is like our attire and clothing. The color matching is natural and elegant. The outer packaging of metal medals is matched. Whether to use ordinary paper boxes or high-end wooden brocade boxes is very particular. The packaging depends entirely on the high-end and authoritative nature of the recipient of the medal.

　　Recently, market research firm LightCounting (hereinafter referred to as LC) released a new report on the theme of “Optics for Artificial Intelligence”. The report points out that artificial intelligence has emerged in the blink of an eye. LC’s first “Optics for Artificial Intelligence” report emphasizes how artificial intelligence is changing computer architecture and networks, and optics plays a key role in this. LC’s artificial intelligence predictions focus on optics. However, the agency said that if there is one more prediction, it is: not only will optics play an important role in the development of artificial intelligence systems, but artificial intelligence will increasingly contribute to the design of these systems at the transistor, chip and system levels.From some points of view, 400g qsfp-dd It is the core driving force to better promote the rapid development of the surrounding markets. https://www.3coptics.com/

　　optical technology

　　The pace of innovation varies across industries. New applications are developed at a rapid pace. Most of them will fail, but some will succeed and seemingly change the world overnight. Software and AI algorithms are being innovated faster than we can imagine. At least that¨s what it seems to be to outside observers, but experts may not see it that way.

　　Innovation in the hardware space is a more gradual but relentless process. Optical connectivity is no exception, and there is solid data to support this. The adoption of silicon photonics has taken a decade, waiting for the technology to bring truly disruptive solutions, such as reliable co-packaged optics. This will undoubtedly happen by the end of this decade, but the forecasts in this report focus on pluggable optical modules deployed in AI clusters – the dominant solution for optical connectivity today and over the next five years.

　　Currently, more than 90% of optical modules deployed in AI clusters are used for InfiniBand and Ethernet connections. As shown in the figure below, the bandwidth required for NVLink to connect to GPUs is 4 times that of Ethernet and InfiniBand. Another bottleneck in AI cluster design is the limited high-bandwidth memory (HBM) available to GPUs, which is another factor in the 3x bandwidth increase.

　　optical technology

　　It turns out that optical switches can be used to scale and reconfigure its AI clusters to improve cluster performance while minimizing cost and power consumption. The research firm expects more companies to adopt this technology in the next 3-5 years.

　　The scale of optical demand for applications in AI clusters is a pleasant surprise in 2023, and the timing of ChatGTP making headlines in late 2022 is particularly significant. Fears of an impending recession and initial signs of declining revenue growth have forced all leading cloud companies to cut spending, including investments in data centers and purchases of optical modules. Strong growth in 2024-2025 is unquestionable.

　　The growth of business from large network equipment manufacturers is the main factor affecting the sales volume of optical modules in 2023-2025. New designs for AI clusters require more optical modules. All previous systems used only InfiniBand networks for optical connections, and most of these systems were AOCs. The latest systems based on NDR (400G) InfiniBand use pluggable 400/800G SR4/SR8 and DR4/DR8 optical modules instead of AOCs. The company also released an NVLink chassis switch designed for 800G optical connections in March 2022. The company is currently testing optical fiber NVLink internally, but these solutions should be available to end users by the end of 2024. If it takes longer, LC said it will have to lower its forecast for 2025-2029.

　　As the pressure of life continues to increase, more and more people are beginning to pay attention to sleep problems. Well-known sleep experts, including Wang Gongquan, Zhang Jing, etc., recommend memory pillows (slow rebound pillows) to improve the quality of sleep. But many people still don’t understand why memory pillows have such effects, and how these pillows are designed and manufactured? In this article, we will introduce the principle and manufacturing process of memory pillows in detail, and discuss whether it really works.For this reason, it can be speculated that knee pillow memory foam The market feedback will get better and better, which is one of the important reasons why it can develop. https://tainengjikang.com/

　　Are memory pillows (slow rebound pillows) really effective? What is the principle?

　　1. The principle of memory pillow

　　Memory pillow, also known as slow rebound pillow, is made of a highly elastic foam material that can appropriately disperse the load according to the weight and heat of the human head, and can also make adaptive adjustments to the curve of the head. When you press your head on the pillow, it will sense the contour of your head and gradually adapt to the shape of your head. When you leave the pillow, the pillow slowly rebounds to its original shape to improve comfort and support. Memory pillows usually consist of three parts: outer cover or pillowcase, liner or filler and memory foam.

　　Are memory pillows (slow rebound pillows) really effective? What is the principle?

　　2. Manufacturing process of memory pillow

　　1. Raw material preparation: The main raw material required for the production of memory pillow is polyurethane foam material, and other ingredients are also required, such as catalysts, detergents, stabilizers, etc.

　　2. Foaming: Foaming is a key step in the manufacture of memory pillows. After the raw materials are mixed at a certain temperature, they are pumped into the mold for foaming. During foaming, multiple parameters such as temperature, pressure, and time are strictly controlled. When the foam is formed, it needs to be processed with an oven or other equipment to ensure that the foam has a smooth surface and is not sticky.

　　3. Cutting: After the foaming is completed, the industry personnel use automated equipment to cut the foam into memory pillow blocks of various sizes and shapes. During this process, the size of each block needs to be carefully controlled to ensure that they meet the design requirements.

　　4. Packaging: Finally, the manufacturer puts the memory pillow blocks into the corresponding covers, usually fiber nylon or ribbed cloth covers, to make a whole.

　　3. Advantages and Disadvantages of Memory Pillows

　　Advantages:

　　a. More comfortable: Memory pillows have good adaptability to the human body, so they can disperse the pressure between the head and neck, making sleep more comfortable.

　　b. Better support: The memory pillow material has high elasticity, which means it can provide excellent support performance and maintain its shape during long-term use.

　　c. Reduce respiratory and allergy problems: Memory pillows usually have antibacterial and anti-allergic properties, which can reduce respiratory problems caused by sleep.
