Q:Which has, know the power of the electrical, choose the cable formulas. And explain it
Is the interference signal line can not go with the wire,
Q:What is the difference between a shielded cable and a control cable?
You and he said that he did not understand the professional. Indoor use KGB, JDG steel pipe or PVC pipe outside the road with steel, non-road can use PE pipe
Q:Will the two 16 square copper wire with what specifications of the trunking
How to say that interference is certainly some, if you line less words on one or two in the bridge next to do a tube it! The pipe will be a little better. Upstairs that I do not think that although in practice the construction of this practice a lot, because you do not feel the interference, but the reality does interfere with, or science should not be strong and weak must be separated.
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
About 35m distance, with the copper clad aluminum wire, so that basically do not affect the electric car charging voltage. The best use of plastic leather wrapped copper wire, if the copper wire, then the wire will increase slightly, but will not affect the electric car charging. Only the line is too long, the wire sagging pull the charger will be the output of the end of the wire, which may be the charger inside the solder joint pull off. To solve this problem is to extend the output wire, the charger should be fixed to the output line, so as not to affect the charger. I hope my answer will help you. -------------------------------------------------- -------------------------------------------------- -------------------- The above content is based on "stupid do not know" personal experience to write, only on behalf of personal views and opinions, no one shall arbitrarily modify, It is forbidden to plagiarize. Please refer to the source.
Q:1.2 meters below the road can use pvc tube wear armor cable?
MR is a metal bridge laying, the bridge width of 200 high 100
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:Why does the AC welding machine burn out the equipment?
The main role is to protect, the secondary role is insulation, there is a role is to decorate.
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:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
3 + 2 and 4 + 1 are the number of cores of a cable, a cable inside is not a line, is insulated with each other 2 or . 3 +. 4 +1 line, 5 lines , Respectively, called 2 core or 3 core, 3 +2 core, 4 +1 core, 5 and other core. 3 + 2 cable 3 is the three phase lines, the diameter of the line as large, 2 is the zero line and the PE line, the diameter of the line as large; 4 + 1 cable 4 is the same as the three lines and the same diameter, 1 is the PE ground wire is a separate diameter; five core is the phase line, zero line and PE line are the same diameter, 2 core and 3 core is also the diameter of the line. In the end with a few cable, the design specifications are provided! A few words are not clear!
Q:How to determine whether the square of the cable is standard
Horizontal laying of the cable within the cable, generally do not need fixed, natural laying can be. Vertical laying section of the cable within the bridge, with the need to match the line card, the use of tied rope (multi-purpose single insulated wire) one by one fixed cable, fixed spacing should meet the requirements. According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
