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:150,120,95,50,25,10,4 * 1.5,2 * 1.5 how much cable to use the heat shrink tube
(AX-310HHC) cooler cool cool supreme falcon hard drive is now no price or price soaring to buy or To find a friend not used second-hand hard drive if it is a parallel port to buy a adapter card to buy a 50 or so into the best is to spend a 50-60 block to accept a second-hand brand machine chassis down also estimated that 1100-1200 this configuration The purpose is very simple, that is, so you can in the case of cheap as possible to meet a daily life office needs of the machine, and the quality of the parts and not too far behind. Inte the G530 quite some to occupy the low-end market means, first of all its performance than the previous generation of low-end goods E5000 and Athlon 200 series to a little bit, and its power consumption is very low, with Athlon Than the chicken is the gap between wow, which makes his power and heat control is to force, do not need a good radiator. And G530 comes with a nuclear show, the effect does not say how good, the most basic 3D games, such as Warcraft CS play a play or no pressure, but also support the hard solution, see the film also solved the problem. The price is also particularly cheap, less than . almost can be said that the low-end first choice.
Q:Whether high voltage cables can be built in belt corridors
First of all, it should be noted that the short circuit is caused by the current is too large, short circuit occurs when the short-circuit current will be very large, can not be used to describe how many times, and electrical design to consider the wire cross-sectional area will not be great, Heat, so the conductor will be hot
Q:The computer host is always start to stop, resulting in the last can not start. What is going on?
Do not worry, no problem, the power cord can withstand the general high temperature, not recommended to use extension cord, the more joints more easily lead to some inexplicable problems.
Q:What is the difference between a pre-branch cable and a punched clip?
The structure of the PV cable is shown in the table. The difference between the ordinary cable and the PV cable is analyzed: The common cable can be seen from Table 1 that the conductor and the PV cable used are consistent. ordinary cable insulation and sheath can be seen from Table 1 different from the photovoltaic cable. Ordinary cable is only suitable for use in general environment. the advantages of photovoltaic power cable: high temperature, cold, oil, acid and alkali salt, anti-ultraviolet, flame retardant, environmental protection, photovoltaic power cable is mainly used for harsh environment, the service life of more than 25 years.
Q:Power cable ZRYJV-4x70 + 1x35 What does it mean?
51 laying of cables 511 cable laying should meet the following requirements: 1 cable type, specifications should be consistent with the design requirements
Q:Pvc threading tube packaging film how to do attractive, on the grade it? Thank you great god
The control cable that transmits the differential signal, the cable core needs to be stranded. The other with the same general control cable. Search for "Industrial Automation Integrated Cable Solutions".
Q:Engineering materials inspection, all types of cable wires should be issued a test report?
Is the aluminum core armored cable for outdoor high pressure conforming to the specification
Q:Calculation method of wire and cable outer diameter
Tell the truth like a three-core cable, five-core cable calculation is more complicated you math good painting geometric map can still be considered
Q:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.
