Q:Is fiber optic cable completely immune to electromagnetic interference?
Hi There, The 220 volt AV power cable will not cause any interference but it is not a good idea. The fiberoptic cable should be ran separate. It is a little more work but the right way to route the cable. You have to be very careful not to exceed the bend radius and wrapping around an existinf power wire might cause a problem. =====this is from the link below======= Do not install a fiber optic cable in a conduit or duct that already contains cabling, regardless of the cable type. Existing or new empty ductwork can be modified to accept several different installations by the placement of innerduct within it. ======================================... Hope this helps, Al
Q:1.2 meters below the road can use pvc tube wear armor cable?
The former bv4 square copper wire is a single strand of hard copper wire, the latter BV4 square copper wire is multi-strand soft copper wire. Core (coredwire), with steel sheath for the outer tube filled with iron alloy powder to do core material, cross-section for the circular or rectangular line body. Also known as cored wire. It is used as a steel-making furnace outside the refining of the feed method to add refining agent and alloying agent. Can be directly added to the deep steel, the molten steel for deoxidation, desulfurization, degassing and non-metallic inclusions denatured treatment, to eliminate the aluminum deoxidized steel in the continuous casting steel | iron when the nozzle plugging the problem. As the deep addition of alloying elements in the molten steel, so the alloying element recovery rate is high and stable, the steel components can be fine-tuned to the best range. The reproducibility of the results is good.
Q:Can you buy amp power cables for any amp?
most amps use the same cable, so it shouldn't be a problem, through your amp in a car, (to double check) and check the local music stores, electronics shops, or Radio shacks
Q:what connects a monitor to the processing unit?
Well the Cable to your Monitor Connects to the Video Card Port, which connects to the motherboard.
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
" Why should the closed wall or protective wall closed on the second side of the closed junction box? This need to understand if you do not add this closed junction box, what kind of harm Civil air defense project in the closed wall is divided into the clean area and the area of ​​the infected area, and the wire tube in the thread after the inside is a cavity, directly through the wall to communicate with the cleaning area and exposed areas, so wartime works outside the dyeing The poisonous air can penetrate into the clean area through the cavity inside the wire tube, which is harmful to the personnel inside the project And the installation of a sealed junction box, you can thread in the line after the box filled with sealing material to block the tube cavity connectivity This is why the electrical safety pipe in the air defense project must pass the closed wall or protect the closed wall when the two sides must be closed in the closed junction box reasons
Q:How to calculate power cable size, tell me formula?
rated current = 200 amp
Q:Wire yellow and green, respectively, that line of fire or zero line
Suggestions or online shopping it Feeling very difficult to match the silicone sleeve, the Internet is very easy to buy, about 10 yuan or so, C430. I just bought a Taipower c430 last month, did not buy silicone sets, bought a Moog MP4 package, that with a silicone sleeve machine becomes ugly. Hope to help the landlord.
Q:We say that the size of power cable is 4 core, 150 sq.mm. What would be the diameter of this cable ???
If the size of the cable is 4 core, 150 sq.mm; = the cross sectional area of each core is 150 sq.mm. The diameter of each core is gotten from the formula C = ╥d. From this $ substituting values for ╥ and C; We find that d = 150 / 3.142. = d = 47.74mm :. for 4 cores, diameter of cable = 47.74 * 4 = 190.96mm However, note that this is only mathematical. On the field, the dimension of a cable is usually specified based on the number of cores it has, and the cross sectional area of one of the cores as the cores are all of the same size.
Q:Where Can I Purchase Graphic Card Power Cable?
should have come with a power cable. sometimes these are hidden in a compartment inside the box. take all the inner cardboard out. It would be pretty unusual for one of these cards to ship without the cable.
Q:The power cable troughs are divided once and twice
Can be used for overhead, buried and pipeline laying of the cable line
