Product properties:
1. The long-term working temperature allowed by overhead conducting wires is 70°C;
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: Did not find the relevant norms. Fiber optic cable should not be affected by interference, electric corrosion this piece without taking into account? More
- The final settlement is the completion of the drawings, the first to complete the map on the right, clear
- Q: I've lost the power cable (and other regular connection cables) for my Dell computer but have some from another computer (but don't know the make of them). This might be a stupid question but..can I use these for my Dell computer or do they need to be Dell cables?
- Go ahead and use it, no problem. For the sake of convenience, all PC power cables consists of three wires. .. one for Positive (Phase line), one for negative (Neutral line) and last for Earth. OK, you can also easily make up one if you have the plug connectors.
- Q: Hey guys, I noticed that with heavy use of the power cord to my laptop, a part of the rubber surrounding the cord is open near the insertion part and you can see the wires. I'm just curious how dangerous it is. I don't have another power cord for my laptop, so do any of you have a recommendation for what I can do?
- Use a Popscle stick, cut in half and then attached it with black tape, This will cover texposedoed wires and will also keep the wires straight and keep them from bending. Good Luck Joe The Old Computer Guy
- Q: When I plug and unplug a power cable to the net in my home for let's say, 50.000 times a day, why doesn't my electricity-meter not count that power for the monthly electricity fee?When I unplug the cable the cable should still have some electricity flowing through it at the moment of unplugging. That electricity disappears very shortly after . But after unplugging it, it doesn't have any electricity anymore. So some electricity is lost right? How does this work?
- by electricity I assume you mean electrical energy. power is the rate at which electrical energy is consumed. Power is generated by the flow of electrical current across a potential difference. Let's use an analogy. A cable is like a water pipe. Current is like the flow of water in the pipe. Pressure is like potential difference (voltage). When there is a difference in pressure at the two ends of the pipe, water will flow through the pipe. The flow of water carries energy, because it can be used to spin a paddle wheel (motor), and the friction of the water against the pipe (electrical resistance) generates heat. I think your question is something to the effect of, if I suddenly remove the pressure difference across the pipe, won't there still be energy in the water flowing in the pipe, and isn't that energy wasted? Well, there's a difference between water and electrical current: the electron hardly weighs anything. There's very, very little energy stored in the motion of electrons in a wire. When the wire is disconnected, the electrons come to a stop almost immediately, and the amount of energy wasted is infinitesimal. I hope that sort of answers your question.
- Q: ok, i want to install and upgrade the sound system in my car, volkswagen 2006, but i dont know where to run the power cable from the battery in engine compartment to the trunk where i place the amplifiers, anyone who knows, please help me out. thanks
- Think outside the box. Literally. You don't have to go through the passenger compartment...you can run the wires under the vehicle. Just be sure to tie them up well. Good luck.
- Q: why is power cable not recognized by notebook?
- This most likely isn't a windows 7 problem at all. It's more likely there would be some damage to the internals of your power cable at some place. Usually if there is, it's in the connecting end or the power conversion box. I would try a replacement cable first if you can. If you don't' have one, take it to a pc shop and see if they can use a test adaptor. If theirs works, it's the adaptor. If theirs doesn't, it's then more likely the power port on your pc is damaged.
- Q: on the end of the cable that connects to the laptop not the power outlet
- That cylinder is called a choke. The purpose of the item is to deflect electrical interferences from the outside sources...like telephones, 2-way radios, ect. It also works as a shield for the brick or power converter that your laptop uses. It also puts out signals that could interfere in other devices.
- Q: The Leader of the band inists that all power cables connected to the amplifires be placed away from the performance area.
- To prevent injury to performers and to protect equipment from potential shorts and for fire safety.
- Q: My ISP had installed an outdoor antenna from where a white RJ45 cable runs into a little white box (which is plugged into AC outlet) and from the same white box i do have another RJ45 jack plugged into my laptops NIC card. I came to know that the white ethernet cable is Power over Ethernet cable which carries the power as well as data. I just want to know if i can plug that ethernet directly into my laptops NIC card ? Can i do that will there be any harm to my laptop's NIC ??

- Q: One day, all of a sudden my amp stopped working. I inspected the battery terminal and noticed their was corrosion on both terminals, cleaned it off, and I inspected the fuse in my positive wire for my amp and noticed the fuse was blown, replaced it and the amp would still not power on, I reinspected the fuse again and it had already blown, I replaced it once more and it did the same thing.
- Theres a short either in the power cable or in the amp internally. Make sure theres in no portion of the cable thats rubbed through. Its more than likely a short to ground, or something internal to the amp. Make sure the fuse has the proper amp rating too. good luck
