Feature:
1,it has characteristic of strong moisture absorption,big expansion rate and quick expansion velocity.
2,small resistance can make cable has semi-conductivity and weaken the electrical field strength effectively.
3,high mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.
4,it is heat-resistant and can bear high instant temperature.cable with this product can keep stable performance at instant high temperature.
Storage:
it should be stored in dry house,kept away from source of fire and not to be exposed to the sunshine.the shelf life is 6 months after the manufacturing date.also it should avoid moisture and mechanical damage during storage and transportation.
- Q:What are the varieties of wire and cable (detailed point)
- Cable regardless of the definition of the number of elements in the definition of a few such as: YJV-3 * 50 + 1 * 16 calculated the number of lines is always a different, different wire rules Model input: bv-2 * 2.5 / bv-3 * 4 (different material), bv-2 * 2.5 + 3 * 4 (the same material)
- Q:Wire and cable CCC product consistency is what
- Wire of course, is to use a good slightly, the first life, ah, can not buy cheap because of cheap, like China's top ten brands to buy the brand on the purchase of these brands I feel very good ah, Po Sheng , Luneng Taishan, Far East, Shenghua cable, on the up, prosperous photoelectric, Nexans Nexans these brands of wire is still very good. The landlord you can go to the above to learn more detailed information ah, the top ten wire brand is very detailed, the landlord can understand very clearly, the above brand is very good, my father last time to go above to see, and then buy
- Q:Apple mobile phone does not support this charge when charging this thing how to charge
- Yes, it is more conducive to the protection of the battery, but if no power out of power, the data can not be saved ah, and you have to put the battery on a regular charge
- Q:Engineering materials inspection, all types of cable wires should be issued a test report?
- This approach is a lot of the general is to extend the city line, that is, line 220V AC line lengthened, some in Taobao. 2. to extend the low-voltage line, engage in a power plug on the plug, the same set of seats, you can easily do an extension line, when you want to use, docking about it, when you can not close up. This is also on Taobao, when to buy, pay attention to the socket, plug the model to the on.
- Q:How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more
- The second floor of the formula is correct, my space also have this formula, with armor and no armor in the current no difference, there are differences in the installation, usually buried to armor, overhead or bridge without armor, you give the model is not Armor, YJV-4 * 240 without armor, YJV-22-4 * 240 armor,
- Q:How are various wire and cable models named?
- Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.
- Q:Remove the computer and wash it off. What the motherboard did not move it, that is, the dust of those dust sasses, as well as the other wire of the skin what Sassafras wash, but the computer re-connected to the Internet when the old mistakes . and the lower right corner of the red Fork appears, disappeared after the emergence. The The Said the network cable is not plugged in, but the MODERN that POWER, LINK, LINE, 3 lights are normal display. The The This is how the matter, and just also appeared keyboard and mouse just start the machine can also be used normally, but in a moment to fall, and then plug their plug re-plug the mouse lights can be displayed, but the lights on the keyboard simply do not Bright, restart the computer but good, what is going on? bother. The The I hope the master quickly to help me, and this machine is relatively old ah No problem added: on a machine, just tried to re-create a connection in the network neighborhood, useless more
- Galvanized pipe itself with anti-corrosion coating, you can not do anti-corrosion.
- Q:Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more
- The proportion of the cross-sectional area of the cable through the embedded pipe is 20%
- Q:Wire and cable model ZD what does it mean
- The middle of the line is not a problem where there is a problem in the place where the joints check the place of the joints can not do the lines are out to check the time and effort
- Q:IPhone6 This cable or accessories have not been certified how to solve
- Labor costs you can and workers to discuss, and some labor costs are calculated in accordance with square meters, and some are calculated in accordance with the day, the specific or ask the local construction team
