Q:What are the requirements for the spacing between the strong and weak wires?
DIY notebook, I recommend you look at the Jingdong Mall, where there are genuine hardware and equipment, that is just the same as the same to buy back, you have to go home to assemble it! Such as CPU, graphics cards, hard drives, processors, heat sinks, monitors and the like can be bought
Q:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
What is the current good computer configuration on the market? The price of 4000 yuan or so no more than 4000 assembly parts to write down the price Thank you.
Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
Cable bridge at both ends to be installed across the ground wire, ground wire diameter can not be less than 16mm2. Wire ends and wire ends of the middle box to be installed at both ends of the ground wire, grounding wire diameter can not be less than 6mm2. Full length bridge with the grounding system connected to not less than 2. Cable bridge is divided into trough, tray and ladder-type, mesh and other structures, by the bracket, arm and installation accessories and other components. Can be set up independently, can also be attached to a variety of structures (structures) and corridor stent, reflecting the structure is simple, handsome in appearance, flexible configuration and easy maintenance features, all parts are required galvanized, installed in the building Outside the bridge, if it is in the vicinity of the sea or belong to the corrosion area, the material must have anti-corrosion, moisture resistance, good adhesion, high impact resistance of the physical characteristics. According to the relevant provisions of the specification, galvanized cable bridge for a good grounding. galvanized cable tray direct board each fixed bolt contact resistance should be less than 0.005Ω, then the cable bridge can be used as a ground trunk (dusting cable tray should not be used as a grounding line), the resistance of each cable bridge can be the following formula Calculate: r = ρ · L / S where: ρ = 15 × 10Ω-6 / cm (20 ℃); L = length calculated by 100mm; S = cross-sectional area of ​​cm2. The unit resistance value of the ladder on the pallet is shown in Table 2. The unit resistance value of the cable duct is shown in Table 3 The resistance of each ladder (or each cable slot) after the installation of the cable tray is the total: R = R (r + 1 / 3r ') where: R - ladder, that is, (cable trough) total length of the total resistance (mΩ); r - ladder unit length resistance (mΩ / m)
Q:Brief description of the difference between cable and cable.
1. home with a wired out, for a wireless router bar, the line of the problem are resolved
Q:20 tons of double beam traffic acceptance standards and content which
This phenomenon is generally the audio input has an AC signal amplified by the amplifier after the results, supplies a little short and good quality of the input of the smooth exchange of spring spring to help Tong burst Kun line test, if not improved that is the receiver problem.
Q:What is the difference between a trough bridge and a tray tray?
Many, with the cable where the requirements should be used bridge.
Q:How to find the phone number on the 110 patch panel
Cable ends should be marked with cable head symbols, the middle line should also be different from the ordinary wiring. Bv at the beginning of the general wire, with YJV or vv is generally a cable, but not limited to these
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Sub-strong electric power cable control cable transmission cable and so on
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Look at the computer and television, respectively, what interface are generally computer and television are more VGA, followed by HDMI, the new out there will be DisplayPort connection at both ends of the wire type is also very rich, VGA-VGA, HDMI-HDMI, etc. also Adapter cable, such as DVI to VGA and one according to the computer and television interface to select the wire, hard link established, win7 will automatically identify, I use the flagship version, feel better than XP. You can choose to clone the screen or expand the desktop and other operations, computer monitors Internet TV while watching movies, like.
Q:Can 110kv and 10kv cables co-share with trenches? What is the relevant specification?
The same is 1080P resolution, the computer with the TV is not full screen, it is possible that the frequency of computer graphics output and TV default frequency is different (the national standard is PAL50 Hz), so as long as the graphics output frequency into 50 Hz will be full screen. Win7 mouse right click, select the resolution, the remaining steps see below:
