Progress

Q: I would like to ask my new workshop power consumption of about 500KW, injection molding machine, 60KW . 40KW . 20KW . the other 20KW, how much should the wire? Respectively how to use lines and switches more: No way to save money! Moreover, the signal to you there, almost all attenuation finished.

Q: Apple 6splus charge may not support this accessories how to do more: 5 small cable, if you feel high cost Can be from the distribution box to the circuit The first light using a small cable low-voltage bus to the equipment side, due to the power distribution room to the equipment side will appear more climbing, bus installation climbing very troublesome and affect the beautiful, The bus outlet cabinet uses cables and installs the transfer box on the busbar

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: 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: What do you want to do? Do network cabling buried? Or in the building after the tube?

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 itself on the anti-corrosion, no need to do anti-corrosion treatment.

Q: Wire and cable: RVFV. : RVFSV. : UTP-CAT5E. : SYV-F-75-5 : RVFSP. : RVSP. : RVFVSP. What is the type of wire? Solve! More: If you need an unqualified wire, you can contact this part

Q: Apple mobile phone does not support this charge when charging this thing how to charge: Just show that the sound is still in the host, must be an external sound, your computer monitor can sound it? Not to sound - Bao Haiping studio

Q: What is the difference between "wire" and "cable"?: Inkjet printer is not printed, pictorial machine high definition, generally used in the advertising industry, for large outdoor advertising, the nozzle can choose not necessarily the number of installed, the more spray, spray the faster, a nozzle of the general life 1 year.

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: What are the T and T, s of the wire and cable test type?: May be charging head of the problem, the line may also be a problem. If the warranty can be free for the change.
