Product properties:

1. The long-term working temperature allowed by overhead conducting wires is 70 oC;
2. When there are large-span rare weather conditions and there is less ice coating occurring in heavy ice areas, maximum stress the lowest point of the conductor sag should not be more than 60% of instantaneous destructive power;
3. When the wires are connected, strands around the connecting pipe should not bulge, otherwise the strands of wires in operation will be unevenly stressed, after the joints are pressed, outlets of connecting pipe should be covered with moisture-proof paint to prevent corrosion;
4. When the wires are installed, sag stress of all the wires at the same gear should be the same, and within the range permitted by the limited distances to the ground and exceeding the distance for protection of building, the conducting wire stress can be higher by 10-15% than normal tension.

Scope of application:

This product is applied to overhead power transmission and distribution lines.

Q: What I really just want to know is the equation and basic concept on how to determine the optimal length of power cable needed to connect two poles while knowing only the linear density of the cable.It does not matter how much sag is produced because of limitations due to the strength of the power cable.
you could connect computers via direct cable get right of entry to on parallel port. you additionally can use a bypass cable for this u could desire to remeber a rule for create a bypass cable it incredibly is 1326 ability connect a million cable with third of different and a pair of with 6 th cable of different. have relaxing
Q: What is the role of the power cable shield?
General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use. Wire and cable recommended Ogilvy's.
Q: hai am working with QATAR PETROLEUM i have one job i have to supply barrier i have the barrier power supply for barrier 120/230v which braker and which cablecore with formula i have to submit for approval regardsravi
contained in the former days we used to partition off because of the speeds of not worry-free drives and how records replaced into saved. Now a days, distinct walls do not some thing for speed, the really authentic positives could be a million, once you've a Boot Partition, sufficiently enormous to take care of the OS, and under no circumstances set up any courses on it, then one partition on your courses, and a very last partition on your records. in case you ever favor to reinstall or format the OS, you received’t lose your records. in my opinion even with the indisputable fact that, I don’t partition some thing, I run 500GB for my important force, then use an exterior 1TB for backups. So, to respond to your question a touch extra obviously, searching on the way you've it partitioned, it can slow your computing device down, or do not some thing solid or undesirable. it received't income you in speed except from what i discussed above conserving the OS on a separate partition so it does not get affected by capacity of courses being put in and uninstalled. no count the way you examine out it, 7 drives is way too a lot.
Q: the contant power cables go to my car alarm, led lights, siren, power locks, power windows, and alarm bypass... they are very small thin awg wires... the ignition and constant power cables under ignition housing are alot thicker... is this possible with no problems?
confident, you're able to do this. make beneficial each and every capability twine has its own fuse close to the battery. Addressing the different solutions: this won't drain the battery any quicker than working a single twine to a distribution block; and there isn't any might desire to characteristic a 2d battery except you intend to play the gadget for long classes without the engine working.
Q: Power cable YJV22-8.7 / 15kv-3 * 300 what meaning
National norms are strictly prohibited, but in practice it is difficult to distinguish between personal experience: 1. Power supply AC380 above, absolutely can not be with the signal line control line with the laying; 2. Power load in the variable frequency load is not Can be; 3. AC. AC110 no problem, but may interfere with the monitoring of video images, the signal line must choose shielded cable single-ended ground, the signal is not affected, no problem; 4 encountered this situation, the general control cable, Line in the same pipe laying, power cable to choose a separate pipe laying. If the scene allows, be sure to strictly abide by the procedures to facilitate the completion of acceptance later. Use UPVC ,, that must be buried, the use of plastic pipe in general play two roles: 1. Waterproof 2. to prevent false digging. Plastic pipe can not play a shielding effect, so you must be the power line and the other separated, the best interval of a certain distance, or power lines choose armored cable.
Q: I am currently travelling in Europe and my power cable crapped out. I need a website which offers next-day international shipping. I am currently in Prague and am going to Krakow next; so if you know of a store in either city which would save me the shipping costs, that works, too.

Q: Please, its urgent. Is it possible to use another wire? I don't have money btw.
Put a coat hanger on it and wait for a thunderstorm.
Q: Which is the best way to prevent damage to the laptop / ac power jack when someone trips on the cable ?Dont ask me to buy a Mac since I already have one. This is for my new PC notebook.
I would suggest using the velcro tye's you can get at any electronic store. Try tying off at the leg of your table. You can also use gaffing tape to tape it down to your floor. Gaffers tape usually doesn't leave a residue and is easily removed. Again, you can get it at Home Depot int he electronics section. Oh yeah, and be careful. :o)
Q: I need to change a cable that goes from public power lines to power meter because its skin/protecting shield is peeling off. What happens is that I need to fix this issue as soon as possible but do not know what kind of cable should be used for repair. I would greatly appreciate your help. Thank you!
What did the electrician say? This is not exactly a DIY project, because it requires inspection and possibly permits. You cannot connect this yourself. The size if the wire is related to the material, distance, and power. It may also be related to local practices. The old 60 amp service entrance is illegal, so you may have to upgrade to 200 amp which would be way different for wire size. An electrician will know the codes relevant to your situation. You can probably get the wire at a home improvement or electrical supply house but the electrician will have to make the connections. Plus, it keeps you from frying yourself or the electric company from pulling the plug.
Q: Hey guys I have a compaq sr5550f desktop the power light under the cable is flicking green but the computer will not turn on or off yesterday it was fine but unable to connect to the monitor I have saying no signal? whats up with it it was fine two days ago I unplugged all cables and let it rest and still the same result even if i unplug all the cables it still flickers green the dies off then if i plug it back it does it again help?
Does the fan spin (at the back, near where you plug in the power cable) at all? If not, you probably have a failed power supply that needs replacing.
