Q:Home improvement, the wire specifications generally how to choose? Lighting, sockets, air conditioning with a few square lines? Ground specifications can be lighter than the line of fire, zero line?
You can use, but look at your LCD TV there is no DVI port or HDMI port, the best use of HDMI port or DVI port, the specific look at your TV size, if your TV support 1080P, it is best to use HDMI or D fans ridicule guest Piji nine Depends on the end VI, because the VGA can only 1080I can not 1080P, with HDMI or DVI display will be better.
Q:Cable yjv-0.6 / 1kv-4 * 120 + 1 * 70 What does it mean?
What is your video card? First must be a separate graphics card. If it is the result of the accumulation of porcelain porcelain puzzle, you give up it. Use the DVI interface to connect the computer monitor, connect the LCD TV with HDMI, in the graphics driver settings to nVIDIA graphics card, for example, install the driver, enter the display attribute drive settings interface, click the expansion window "nView", in the "nView Mode ", you can set to" copy "," horizontal span "or" vertical span "as needed. "Copy" means that the contents of the two displays are exactly the same. "Horizontal cross" means that the display of two monitors is connected in the horizontal direction, for example, we want to work in the main display, but also want to watch movies in the auxiliary display, which is a more applicable function.
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
There are four kinds of lines are then connected to the S terminal line terminal line D AV Cable There wherein component color line terminal S and AV Cable used on PSP2000 machine models the XMB output only able to listen to music and video player can not play Delays Shanghai Gan high wet die for splashing simulation games and armpit homebrew terminal D line in the high definition television generally have much use is the most common color components of the line connector 2 are 5 audio support three video lines by able to run all games and homebrew on line scan TV (provided that set - external display settings - select progressive scan mode) If the TV does not support progressive scan, and it can only S-Video and AV terminals as well, so before use Please determine whether the TV supports progressive scan PSP3000 host no more than the above restrictions can use all the features now on the market to sell the line is generally divided into original and assembled, the effect is similar in use, in addition to the D terminal, because it is high-end line, so few assembled, prices are more expensive, probably about more than 500 pieces, AVS component cable original price of the basic recommendations are between 240-360 basic components are assembled in line to buy 30 Around a lot to find on Taobao reputable sellers use effect is good to see you choose which of
Q:What type of cable is the power cable?
Our unit to do the professional cable tray to the current domestic ranking before 3 I did not see we have this certification ah there is a professional health and safety management system has an environmental management system and other quality management system of other scientific and technological innovation patents have a lot of what I do not see the CCC, but you can do the next try you can log in China certification recognized information network - expert column, consult the above experts, these experts have all walks of life experience, can help to you.
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
The 4.0 square wire refers to the air conditioning power cord single copper core cross-sectional area of 4 square millimeters.
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
You say is the power supply power? Is not the power supply voltage! Power supply is W, that is, tile. Power power is insufficient, it is said that the components will accelerate the aging, aging components are easy to burn, components on the motherboard, of course, is burning the motherboard Oh, and power supply is also easy to cause computer instability. Crash, restart .... and so on. If your power is not enough power, it should be for a larger power and is guaranteed quality power such as Hunt, the Great Wall and so on. General 250-300W power supply on it.
Q:Where the computer can be a bare chassis. Which hardware inside the framework
Power cable YJV22-10KV-3 * 400 safe carrying capacity: in the air deposited capacity of 565A, buried 520A.
Q:What kind of material should be selected for the fixing bracket of the cable trunking
2.5 square copper (green, with the threading tube) theory will be able to withstand about 20A current, consider the pipe, temperature and other factors, so according to the actual can withstand about 3 kilowatts of power. In fact the 2.5MM2 copper wire is generally open 16A can withstand about 3.4 kilowatts of power.
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
Although there is a relatively thick cable inside the cable to prevent a very thin cable was broken, but the insulation is not iron, after all, is generally a VB tube is also a corrugated pipe PVC pipe is also too iron
