Q:The difference between power cable and overhead cable
. the power cable occupies less. Generally buried in the soil or laying in the room, the channel, the tunnel, the line between the insulation distance is small, no tower, covers an area, basically does not occupy the ground space. The overhead cable is the opposite. . power cable reliability. Affected by climatic conditions and the surrounding environment, transmission performance is stable, high reliability. . the power cable has to ultra-high pressure, large capacity development of more favorable conditions, such as low temperature, superconducting power cables. . the power cable distribution capacitor larger. Overhead cable is the opposite . the power cable maintenance work less overhead cable is the opposite . the power cable electric shock is unlikely. The overhead cable is the opposite
Q:What is the difference between the control cable and the compensation cable?
The reason why the wire outside the casing, is to protect the wire insulation from external damage. And the wire laying in the cable tray. The bridge has been gas to the protection of the role, so no longer outside the casing
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
Two should be phase line, generally in the three-phase loop corresponding to the color: A phase is yellow, B phase green, C phase red, neutral (that is, zero line) for the blue. If only in the single-phase loop only red and green when the default is red for the phase line, green for the zero line. But not necessarily, some electricians do not follow the requirements, the specific you have to use the pen to know what the
Q:What does the cable (YJV-5 * 6) mean?
ZR-YJV22-4 * 16 is ZR armored flame retardant power cable, YJV22 copper core PVC insulated steel tape armored PVC sheathed power cable, 4 * 16 is 4 core 16 (mm2) section.
Q:The TV shows no signal. The What is the reason for this?
We usually say how many square millimeters (wire) refers to the cross-sectional area of the wire core, that is, according to the diameter of the core calculated cross-sectional area. The larger the cross-sectional area of the wire, the greater the capacity of the power transmission.
Q:What is the heat of the cross-linked cable?
75 indicates the characteristic impedance, the video line 75-3 (100 meters) can work the normal transmission distance 75-5 (300 meters) can work the normal transmission distance 75-7 (500-800 meters) can work the normal transmission Distance 75-9 (1000-1500 meters) can work normally the transmission distance commonly used models are generally SYV75- the same manufacturers may also provide different price products, the specific difference is that the copper used is copper or copper clad aluminum , Or outside the shield copper core number, such as: 96 series (referring to 96 fine copper core weaving), 128 series, etc, the more the number of shielding performance is better, so this need to pay attention to the procurement of products The
Q:Ipad charge does not enter the charge does not support this accessory charge
You ask this is too professional, it is difficult to answer, to ask the air conditioning technical staff Caixing.
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:What is the use of wire and cable per square meter of residential building?
You can use sc. if too long, or bend the best use of the bridge
Q:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
According to the size of the product to open a good plastic mold and then purchase the plastic raw materials to be injected (raw materials depending on your product requirements, advanced point will use To the engineering plastics PE, PS, etc, and even to join the flame retardant, fiber material), the difference is like now with the charger on the use of only PVC3 Called the wire manufacturers according to your request to do a good line Of course, you have the conditions you can pull the wire of their own beer process: mold on the machine (ingredients test mode) --- welding wire and hardware (pin) --- then put the welding hardware on the mold (according to the mold Put five to ten range) - boot molding - detection of another: If you want to have all the country's certification, it is estimated that you no technology is not too, you can not buy that hundreds of thousands of equipment to detect The power line in the material composition and a variety of techniques to wear flattened Fenbao match platinum standard, because the formal power It is too much to be recognized, but you want to do ordinary DC line, such as mobile phone charger or no problem, but the regular factory what automation machine to do, then I do not know, but it is automated machine estimates But also the cost of scary Anyway, ordinary manufacturers do have any questions can EMAIL: qingxinghe@21cncom Do not call me in Google, I rarely said so much, add points to me, huh, huh
