Q:The data line is my online to buy the extension of the line, has been able to use, and today suddenly can not charge the electricity, and pop up the tips, which is why? More

This situation generally have to extend the line triangle can link the ground, the two feet when you use the foot to feel the foot, and step on the bench as long as the non-conductive feel. No seriousness

Q:If you want to sell wire and cable, then what to do in advance to detect? The The The The The

Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.

Q:Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................

About 140 PVC threading tube, which depends on how many lines you row. PPR cold / hot water pipe 42 meters, PPR cold / hot water pipe with 4 m / root and 6 m / root of the points, short will make the joints more recommended to use long, generally longer expensive. Decoration in meters to count, to facilitate the settlement of labor, 42 meters is the amount of my home My house 115 square meters, indoor area of 98 square meters. I hope useful to you. According to the 2011 price, the general brand of wires and pipes, their own materials to buy, without artificial about 4000-5000 yuan. I decorated last year, the package to the decorating company hydropower workers with me to calculate the 9800 yuan it, of course, each region has a price difference.

Q:IPadmini. The latest version 7.1.1 up in the morning to see the non-stop display this cable is not certified does not support this feature. The The Charger original. Not on the computer charge. The Ask God to answer more

The problem lies in the charger between the machine, IPAD charging is to a charging protocol to complete, when the IPAD did not receive the agreement signal will be prompted: do not support this accessory, Apple's products have charging protocol, charging Is through the data line in the two lines and IPAD transmission charging protocol signal when ipad received the charging protocol signal after the machine internal charging circuit began to open the internal charging circuit to charge, the problem is to accept the charge signal is not so prompted not to Support, change the line to try

Q:Apple 6splus charge may not support this accessories how to do more

Sometimes no way, the problem to the owners to solve the common, must wear, the owners agreed

Q:Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More

This is too difficult to give you a way to just try: with a fine wire rope, that is, lift the clothes on the stick so thick, the end of a bend, with a tape wrapped around the head, try can not wear, wear When the possibility of rotating wire rope, if you can go through the success of the half, the key is to use the wire through the more difficult, can only use the cord, hard-line 100% make life difficult.

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

According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.

Q:What is the warranty period for wire and cable?

Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.

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

No need. Galvanized flat iron to do when the grounding grid is not anti-corrosion, but if there is welding or damaged place to become anti-corrosion.
