We may be unfamiliar with the practices and usage of twisted pair wires. For example, it is hard to remember how the standard wire head is implemented. It is also vague to know the cross Line (or direct line) used. Let's talk about some notes. Prerequisites 1. Twisted Pair pin position definition (the crystal head has no clip side, from left to right), as shown in table 1. For Table 1, we only need to remember two points: one is that only one, two, t

For example, 120 mm² calculation: 120*8.89 = 1066.8 kg/km 1 conductor usage: (Kg/Km) = d ^ 2*0.7854 * G * N * K1 * K2 * C D = copper wire diameter G = copper proportion N = bars K1 = copper wire twisting rate K2 = core wire twisting rate C = insulation core wire number 2 insulation usage: (Kg/Km) = (D ^ 2-d ^ 2) * 0.78

This article will start from the copper wire, all the way to the HTTP, for everyone

In product catalogs such as LAN switches, there is a "wire speed (Wire Speed)" In a project that represents device performance. such as "The realization of the wire-speed LAN switch", "support line speed to achieve high-performance" and so on, often in the promotion of product use, people think is the meaning of speed, but in fact really so? Today we'll take a lo

How to quickly insert a three-wire table in the WORD2010, in fact, in the WORD2010, tabulation function is very powerful, rapid generation of three-wire table is very convenient. It takes two steps to generate a three-wire table in the WORD2010. First we need to insert a three-row table in the WORD2010 and insert the table in WORD2010 's Insert Ribbon Table tab.

which does not fit the wiring. Let's take a look at these wired transport media. Copper Medium: Copper medium is a kind of electric signal transmission medium which is widely used in computer network, there are two main twisted-pair and coaxial cable, now the newly built computer network is basically a twisted pair as the transmission medium Star topology network, and coaxial cable is gradually out of the computer network market, Currently the most widely used scene is the cable TV network th

Since the beginning of this winter, many regions in China have suffered a cold wave. Since March November, China's North suffered a blizzard, which brought significant losses and impacts to the national economy and people's lives. On December 24, the Central Meteorological Observatory issued an orange cold wave alarm, which said that from the 24 th to the 26 th, a strong cold air would once again attack northern, western, and some eastern parts of China. This indicates that the "Frozen" phenomen

In reality, wire control headphones produced by manufacturers of various brands cannot be used in a universal manner, and purchasing dedicated headphones is expensive. If there are idle wire control headphones on hand, as long as the interface is appropriate, it can be matched with a little change. Our common wire control headphones, regardless of the interface

Wire Introduction Lightweight protocol buffers, Java Library for mobile devices (compared to the code generated by PROTOC), the number of code methods generated by wire will be greatly reduced, which will help Android apps avoid limiting the number of 65k methods How to use Download the most recent wire jar package, currently the latest vers

I have read a lot of interpretations about this item, especially when Baidu knows that many of them are nonsense, but I cannot read it, so I wrote an article, for you to have a clear understanding of the aspect. 1. Is the optical fiber transmission speed faster than that of copper wires in terms of transmission speed? As we all know, copper wires are what we call cables, transmitting electrical signals, while optical fibers transmit optical signals. Therefore, there are two network access metho

In the grounding system, grounding wire production and installation is very important, the following for this introduction. One, grounding resistance requirements: 1, resistance to less than 4 Ω. The size of the grounding resistor can define the size of the grounding current, the smaller the grounding resistance, the lower the grounding voltage value of the grounding device. This means the size of the grounding resistance value, indicating the g

left a right one, far near, therefore, less than 305 meters in the short place will need to break open network line of the foreskin, will be picked out to connect the camera, long place need to two boxes or even more boxes of the line to pick up, In the wiring when the best welding, bandaged, and pay attention to twisted stranded wire and the problem, so as to ensure that the transmission does not have problems on the line. 5 Go two extremes, cause

In the paper, how to add a three-wire table, so that their paper format to become correct, the teacher also pick up the wrong, here to share a word in the production of three-wire table method. 1, in Word in the menu bar to find "insert--table", select a suitable row. 2, leave the last line, the rest of the selected, right click, select "Borders and Shading." 3, will a

It also supports applications written using the MongoDB driver and applications written using the MongoDB command shell commands. Use the features provided by the DB2 JSON API to process Bson documents. Background inform

In the past, I also saw the acrobatics of "Walking wire", but far from the excitement I saw this time: the length of "wire" is about500Meters (visual), steel wire distance from ground height is1000Meters, "Steel Wire" at both ends of the two mountain peaks, next to the abyss is Wan. The performers ride bicycles, unicyc

It is mainly because of the Quartus II connector, Which is set in the Quartus II connector, you can increase the number that SignalTap II can detect. IntroductionUse environment: US us II 8.0 In (original) How to Use SignalTap II to inspect Reg and wire values? In (SOC) (OpenGL) (Quartus II) (SignalTap II), I have used synthesis attribute encod

I think in PCB design, it is very important to select the width of the wire. It is much easier to know how much current the wire can flow at the maximum. Recently, I am planning to design a thermostat circuit for controlling the self-made small refrigerator. The power is 400 W, the current is 33a, the current is very high, and the PCB design is a headache, but it has been fixed. Directly create a console p

The resistance screen is divided into four-wire, five-wire, and other multi-wire resistance touch screens based on the number of leads. The a surface of the 5-wire resistive touch scr
