How to Use Network Cable Tester_ Application Method of Network Cable Tester
How to Use Network Cable Tester_ Application Method of Network Cable Tester
Now cables are used in all aspects of people's production and life, so mastering the operation method of network cable tester is the most basic requirement for cable users. So how to use network cable tester?Application method of computer network cable tester1. Insert the two ends of the network cable above the main and auxiliary survey lines respectively, and you can insert any head at will;2. Then turn on the switch of the line measuring instrument;3. Observe whether the indicator lights of 1-8 on the main and auxiliary line measuring instruments are on, and the order of lights is correct.4. For example, 1 light on the main survey line instrument should be on, and 1 light on the auxiliary survey line instrument should also be on. If the 1 light on the main line measuring instrument is on and the 2 light on the auxiliary line measuring instrument is on, it indicates that there is a problem with the network cable and it can not be used normally;5. Among the eight lights, as long as the lights 1, 2, 3 and 6 are on, the network cable can be used, because the data is transmitted through these four lines, and the other four lines are not used to transmit data.There are two standards for the order of network cables:1: The standard of t568-b is orange white, orange, green white, blue, blue white, green, brown white and brown.2: The standard of t568-a is green white, green, orange white, blue, blue white, orange, brown white and brown.The first standard is generally used.Second, insert the crystal heads at both ends of the network cable into the RJ45 port of the main tester and the remote test end respectively, and turn the switch to "on" (s is slow gear). At this time, the indicator heads of the main tester and the remote test end should flash one by one.Test of direct connection: when testing the direct connection, the indicator lights of the main tester should flash one by one from 1 to 8, and the indicator lights of the remote test end should also flash one by one from 1 to 8. If this is the case, it means that the connectivity of the through line is OK, otherwise it has to be redone.Test of interleaved lines: when testing interleaved lines, the indicator lights of the main tester should also flash one by one from 1 to 8, while the indicator lights at the remote test end should flash one by one in the order of 3, 6, 1, 4, 5, 2, 7 and 8. If so, the connectivity of interleaved lines is OK, otherwise it will have to be redone.If the line sequence at both ends of the network cable is incorrect, the indicator lights of the main tester still flash one by one from 1 to 8, but the indicator lights of the remote test end will flash one by one according to the order of the line numbers connected with the main test end. In other words, the remote test end cannot flash in the order of the above steps.Phenomenon of wire open circuit testWhen one to six wires are open circuit, the indicator lights of the corresponding wire number of the main tester and the remote test end are not on, and other lights can still flash one by one.When 7 or 8 wires are open circuit, the indicator lights at the main tester and remote test end are not on.Phenomenon of wire short circuit testWhen two wires are short circuited, the indicator lights of the main tester will still flash one by one in the order from 1 to 8, while the indicator lights corresponding to the two short circuits at the remote test end will be lit at the same time, and other indicator lights will still flash one by one in the normal order.When three or more wires are short circuited, the indicator lights of the main tester still flash one by one from 1 to 8, while the indicator lights corresponding to all short circuits at the remote test end are not on.

It will also point out someWe have a cable tester, a type of cable plug that is used to ensure the quality of cables. The cable tester has four prongs and is connected to the main power supply by one wire. These wires are also connected in pairs: one goes to the positive terminal and another goes to the negative terminal. When you want to connect two wires together, you need to connect them first in pairs (with positive and negative terminals) and then separately in pairs (with positive and negative terminals) as shown below:In order for you to test whether or not two cables are connected properly, you will need a cable tester socket adapter. This device looks like an ordinary socket with only one wire on it. The connection between these two wires is made with an adapter. You can find theseIn order to make sure you get the best deals on TVs, Blu-ray players, etc., you need to do some research. You might have heard about a TV review site named "BestBuy" or a "Best Buy". You might also have found yourself going there to check out the latest offers only to be disappointed when your search didn't turn up anything interesting.As you've probably come to realize, there are a lot of possibilities when it comes to finding the best deals on TVs, Blu-ray players and other gadgets. But even if it is easier than ever before, there is still so much information that you need in order for these tradesmen and women to be able to offer quality recommendations.Best cable tester ensures that cables are properly connected to all the devices.With accurate, fast and reliable cable testers, you can easily save your business money.The cable tester software is an essential tool for any cable equipment buyer.

They also include various other inputs and outputs from home appliances like refrigerators, washing machines and dishwashers.The best cable testers can also be used in different situations to find out whether your device is working properly or not. If your computer isn't functioning properly, you should check the cable of it first before taking any action on it immediately to make sure that there are no faulty connections or miswired devices present in the system because of which your computer won't work properly at all. On the other hand if something goes wrong with a certain deviceToday's cable tester software/hardware is very sophisticated and works in a particular niche. This makes it a perfect fit for cable testers who are looking for precise information such as the channel number, the length of the cable and the condition of the cable.While there may be other software that can do these tasks, this software provides them quite well. This is why you should consider purchasing this software to get some competitive edge in your field.
Basic Knowledge of Cable Installation
Basic Knowledge of Cable Installation
Whether the cable is installed correctly or not is directly related to our personal safety, so it is very important to learn the correct cable installation method. First of all, we need to understand the precautions for cable installation: first, when the mining cable is placed in parallel with the heating pipeline, it shall be connected with a distance of 2m, and when interleaved, it shall be connected with a distance of 0.5m. Second, when the cable is placed in parallel or interleaved with other pipelines, it shall be connected with a distance of 0.5m. 3、 When the cable is directly buried, the direct burial depth of 1-35kV cable shall not be less than 0.7m. IV. when the cables of 10kV and below are placed in parallel, the clear distance between each other shall not be less than 0.1M, 10-35kV shall not be less than 0.25m, and the distance during interleaving shall not be less than 0.5m. V. the minimum bending radius of the cable shall not be less than 15d for multi-core cable and 20d for single core cable (D is the outer diameter of the cable). 6、 Discussion on 6kV and above cables. A. When placing the cable terminal, the semi-conductive barrier layer must be stripped off. The insulation shall not be damaged during operation. Knife marks and the environment with high and low resistance shall be prevented. If necessary, it shall be polished with sandpaper; The end of the barrier shall be flat, and the graphite layer (carbon particles) shall be broken and cleaned. B. The copper barrier and steel armor at the end of plastic insulated cable must be well grounded, and this criterion should also be observed for short routes to prevent electromotive force at the end of steel armor during three-phase unbalanced operation, even ignition and burning of sheath. Tinned braided copper wire shall be adopted for grounding outgoing line. Soldering iron shall be used for soldering when it is adjacent to cable copper strip, and blowtorch shall not be used for sealing welding to avoid burning insulation. C. The three-phase copper barrier shall be connected with the ground wire respectively. The detailed barrier ground wire and steel armor ground wire shall be led out separately and insulated from each other. The position of the welding ground wire shall be as low as possible. 7、 Fundamental requirements for cable terminal and center discussion: A. excellent conductor connection; b. The insulation is reliable. It is recommended to adopt radiation crosslinked heat shrinkable silicone rubber insulation material; c. Excellent sealing; d. Sufficient machine strength can comply with various operation conditions. 8、 The cable end must be waterproof and corroded by other corrosive materials to prevent breakdown caused by aging of insulation layer caused by water tree. 9、 Crane or forklift must be used for cable loading and unloading to prevent horizontal transportation and placement. Cable car must be used for large cable placement to avoid external force damage to the cable or scratch the insulation layer due to manual drag. 10、 If the cable cannot be laid in real time for some reason, it shall be stored in a dry place to prevent sunlight exposure, water inflow at the cable end, etc. Secondly, it is also a link that can not be underestimated, that is, it is necessary to conduct acceptance inspection on the installed cables to see if there are omissions. 1、 First, the user shall check and accept the cable to see if it is damaged, and the construction personnel shall test the resistance and insulation resistance of each cable with a multimeter to confirm whether the cable resistance and insulation are normal, and record it. 2、 The supervision personnel of the user are invited to accept the whole laying. The main acceptance items are: a) whether the insulation layer is laid smoothly; B) If reflective film is installed, check whether the laying of reflective film is smooth; C) Whether the barbed wire mesh is installed smoothly and fixed. D) After the heating cable is energized, check whether the surface temperature of the cable has increased significantly, and sign on the acceptance sheet for confirmation.

Your more then welcome to them. Feel free to email me at7. Soldering a SATA-Data cable to a HDDActually, there's only 4 pins that matter You have 4 wires for signal, 2 per 'channel' and 3 grounds (which should be tied together anyway). The 4 bare wires on the outside of each pair/channel are ground, and any three should work.You absolutely do not want to do this without a multimeter. That said, I strongly recommend plugging one end into a switched off PC or drive and checking continuity between all 4 ground wires (on the outside) and checking each pin and its corresponding wire to ensure you know which wire is which. If you do not have a multimeter, you ought to get one and learn the basics of using it - continuity testing is about the simplest function in one. I am also not sure if trace lengths matter here, and that may be an issue. Not sure how to deal with that considering everything I've seen in the question though
Follow the Cable Fault Tester Supplier to Deeply Understand the Cable
Follow the Cable Fault Tester Supplier to Deeply Understand the Cable
The lead of the motor is not only related to the rated voltage of the motor and the open circuit voltage of the rotor of the wound rotor motor, but also directly related to the current carried by the motor winding and the actual service condition of the motor. The selection of lead specifications should first be determined according to the withstand voltage value. The cable has a withstand voltage range. This rule must be followed when selecting. Below, the supplier of cable fault tester will take you to have an in-depth understanding of cables. Select the lead of corresponding voltage level according to the voltage requirements of the motor. The voltage level of the lead shall not be lower than the rated voltage of the motor winding. For example, for 10kV and 380V motors of high-voltage motors, the voltage value of the cable is very different. In addition, besides the voltage and current requirements, the insulation grade of the cable of the motor lead is also very important. According to the insulation grades of class B and h, the insulation heat resistance of the motor is different, and the material of the insulation material is also different. It must be noted that if the class B lead is used in the class H insulated motor, the possibility of lead damage and ground fault is very high. The cable fault tester supplier interprets the provisions of motor lead in the national standard: 1. Determine its necessity according to needs. According to the standard, if the motor has a power cord, or in order to facilitate connection with other equipment, provide a guide cord extending out of the motor base and a plug connecting the power supply line if necessary, the cord and plug shall comply with the provisions of the relevant standards of the product or the relevant standards of such equipment. Especially for small motors, winding wires can be used to connect with equipment or terminal blocks, but for motors that must undergo relevant insulation treatment, soft wiring must be adopted, and the provisions of terminal blocks must be added. Unless grounding is not required, these flexible wire bundles must have grounding conductors. Leads (including ends) require different colors and markings. Most motor manufacturers use three-color leads for three-phase motors, and some motor manufacturers use labels to distinguish them. However, for grounding wires, they are adopted according to standards. 2. Voltage and current requirements. The standard stipulates that the rated voltage of the guide flexible cable must be under the maximum working voltage of the motor, and its load flow must be at least equal to the load current of the service factor or 125% of the full load rated current, whichever is the larger. The flexible cord insulation shall withstand the working frequency withstand voltage test of the circuit. 3. Protection requirements for leads. In addition, there are measures to eliminate the possible tension, or guide the flexible cable (power cord) not to expose the motor. An insulating protective layer and clamping device are set at the outgoing part of the flexible cable to prevent the external tension from being transmitted to the internal wiring and prevent accidents caused by the rotation and displacement of the flexible cable. 4. Limitations and insulation requirements. In addition to other protective measures, the introduction of flexible cables into the motor shall be prevented. The clamping device for clamping and fixing flexible cables is made of insulating material, made of metal material and requires insulating lining.
Introduction of Underground Pipeline Detector
Introduction of Underground Pipeline Detector
Classification of underground pipeline detectors 1. One category is to detect metal pipelines, electric / optical cables and some non-metallic pipelines with metal marker lines by using the principle of electromagnetic induction. This category is referred to as pipeline detectors for short. Advantages: fast detection speed, simple and intuitive, convenient operation and high sensitivity. Disadvantages: (underground pipeline detector) when detecting non-metallic pipelines, non-metallic probes must be used. This method is laborious and needs to invade the interior of the pipeline. 2. The other is to use electromagnetic wave to detect underground pipelines of all materials, which can also be used to find underground buried objects, commonly known as radar, also known as pipeline radar. Advantages: (underground pipeline detector) can detect pipelines of all materials. Disadvantages: high requirements for environment, poor sounding ability (it is difficult to check pipelines with deep buried depth), and high requirements for operator quality and experience. Any instrument is not superior and needs to be used together in order to give full play to their excellence. Traditionally, pipeline detectors only refer to pipeline detectors using the principle of electromagnetic induction, and also use * many instruments.

Application of Cable Fault Locator
Application of Cable Fault Locator
The application of cable fault locator in power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable. Dear customers: the company also has products such as underground cable fault tester, cable identifier and cable tie tester. You can call the company's service phone through the web page to learn more product details. Perfect and beautiful service is our pursuit. New and old customers are welcome to buy their favorite products at ease. We will serve you wholeheartedly!
