Single-core Cable and Multi-core Cable

  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.In order to open the market, shielded twisted pair cable Constantly improve the ability of business development and create an extraordinary brand image for it. 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.

  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.

InfiniBand vs. Ethernet What are they

  As interconnect technologies, InfiniBand and Ethernet are different, and it is difficult to say which one is better. They continue to develop in different application fields and become two indispensable interconnect technologies in the network world.The industry believes that, 400g qsfp-dd The development of our company marks the rapid and steady progress of the whole industry. https://www.3coptics.com/

  

  InfiniBand vs. Ethernet: What are they?

  

  InfiniBand Networking

  

  From a design perspective, there are big differences between InfiniBand and Ethernet. As a network interconnection technology, InfiniBand is widely used in supercomputer clusters due to its high reliability, low latency, and high bandwidth. In addition, with the development of high-performance computing, InfiniBand has also become an ideal choice for GPU server network interconnection technology.

  

  To achieve the original data transmission rate of 10Gbit/s on 4X cables, the InfiniBand standard allows the transmission of single data rate (SDR) signals at a basic rate of 2.5Gbit/s on each channel. A single channel can be expanded to 5Gbit/s and 10Gbit/s respectively, and the maximum data transmission rate is 40Gbit/s on 4X cables and 120Gbit/s on 12X cables, thus enabling InfiniBand networks to have double data rate (DDR) and quadruple data rate (QDR) signals.

  

  InfiniBand

  

  Ethernet Network

  

  Since its introduction on September 30, 1980, the Ethernet standard has become a widely used communication protocol in local area networks. Unlike InfiniBand, Ethernet was designed with the following goals in mind: How to easily transmit information between multiple systems? It is a typical network designed for distribution and compatibility. Traditional Ethernet mainly uses TCP/IP to build networks and gradually develops into RoCE.

  

  Generally speaking, Ethernet networks are mainly used to connect multiple computers or other devices (such as printers, scanners, etc.) to a local area network. It can connect an Ethernet network to a wired network through fiber optic cables, or it can connect an Ethernet network to a wireless network through wireless networking technology. Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, and Switched Ethernet are all major Ethernet types.

  

  Ethernet

  

  InfiniBand vs. Ethernet: What are the differences between them?

  

  Cluster data transmission bottlenecks in high-performance computing scenarios are the original design target of InfiniBand, and it has become an interconnection standard that meets the requirements of the times. Therefore, there are many differences between InfiniBand and Ethernet in terms of bandwidth, latency, network reliability, network technology, and application scenarios.

  

  Bandwidth

  

  Since the advent of InfiniBand, the development speed of InfiniBand network has been faster than Ethernet. The main reason is that InfiniBand is used for interconnection between servers in high-performance computing and to reduce CPU load. However, Ethernet is more oriented to the interconnection of terminal devices and does not require too much bandwidth.

  

  For high-speed network traffic exceeding 10G, if all data packets need to be unpacked, a lot of resources will be consumed. The first generation of SDR InfiniBand runs at 10Gbps, which not only increases data transmission bandwidth and reduces CPU load, but also allows high-speed network transmission to offload CPU and increase network utilization.

How to save money when sending large items by international express Here is a complete guide!

  In today’s globalized world, sending large items across borders has become a daily need for many people, whether it is moving, studying abroad or cross-border e-commerce. However, facing the high international express delivery costs, especially the shipping costs of large items, people are often discouraged.Actually, it’s not just this reason, sourching agent Its own advantages are also obvious, and it is normal for the market to perform well. https://flyportt.com/

  

  Don’t worry, today we will talk about the money-saving strategy for sending large items by international express, so that your wallet will no longer be “hurt”!

  

  >. Clarify your needs and choose the right channel

  

  1. International air transport: flexible but with restrictions

  

  Although international air transport is fast, not all options are suitable for large items. Postal parcels and international special lines are basically excluded due to weight restrictions. Although international EMS can theoretically deliver up to 30kg, the delivery time is unstable and the cost increases with weight. Commercial express (such as DHL, UPS, etc.) has no weight limit, but there will be an overweight surcharge for more than 60kg, and the volume weight calculation is not favorable for large items. If the quantity of goods is large and there are requirements for delivery time, air delivery is a good choice, with relatively affordable prices and stable delivery time.

  2. International shipping: cost-effective choice

  

  For large items, sea shipping is undoubtedly the most cost-effective option. Although it takes a long time (usually more than 25 days), the freight is much lower than air shipping, which is especially suitable for situations where you are not in a hurry to receive the goods. However, please note that some countries may not be able to ship by sea, so you need to consult and confirm in advance.

  3. European Railway Transport (China-Europe Express): Stable and Economical

  

  If your destination is Europe or the Middle East, China-Europe Express is a good choice. It is not only cheap, but also relatively stable in terms of logistics time. Although the overall time is relatively long (20-35 days), it is suitable for goods that have a certain tolerance for time.

  

  save money

  

  4. Truck transport (China-Europe truck transport): a balance between speed and economy

  

  As an emerging mode of transport, China-Europe truck transport stands out for its speed close to air transport and price far lower than air transport. The average delivery time of 15 to 25 days, coupled with the price being only about 60% of air transport, makes it the best option in some scenarios. It is especially suitable for customers who have certain requirements for timeliness but want to save costs.

  

  >. Reasonable packaging to reduce volume weight

  

  Large items are often accompanied by high volume weight charges, so reasonable packaging is crucial.

  

  Using lightweight materials such as bubble film and foam board instead of heavy cartons can effectively reduce volume weight and thus reduce freight. At the same time, try to place items compactly and reduce gaps to achieve the same effect.

  

  save money

  

  >. Take advantage of discounts and offers

  

  Many international express delivery companies will regularly launch discounts or membership offers. Paying attention to this information and placing orders at the right time can further save on shipping costs.

  

  In addition, if you cooperate with reliable logistics agents, they can often get more favorable prices and provide professional packaging and customs declaration services, making your mailing process more worry-free and labor-saving.
