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: Its an 03 jetta with monsoon amp. I need step by step instructions on how to run the power cable. Pictures would be nice too. Thanks!!!!!
- think of exterior the container. actually. you do no longer could desire to bypass for the period of the passenger compartment...you could run the wires below the automobile. only be valuable to tie them up nicely. stable success.
- Q: Hello,I recently bought a kotatsu and I really need some help. The power cable is of course Japanese... And I need some type of converter.On the part of the cable that plugs into the radiotaor it says:PSE (It's in some square box)JET MR7A 250VOn the end that plugs into the wall it says:PSE (It's in some square box)JET MR7A 125VI''m not sure if a simple small converter to let me put the Japanese cable into my wall is enough, I think I need something extra to make sure nothing goes into flames.Inside the Japanese instruction manual I found some info ... However, I'm not really sure if it is related to the power supply or not...AC100V 50-60Hz400W3.1 (Probably the length of the cable) 1.3 (Same here I think)140Wh 60 Wh55C 37CPlease help me, what should I get to be able to use the cable in Europe. Any links at all will be helpful...Thanks.
- Don't worry too much about what the cord says. Worry about the power requirements on the appliance label, and making sure you are feeding it with the voltage required, with a capacity within the range. In your instance, you will need a converter transformer that converts your outlet voltage to 100V, and has 550 or larger watt capacity.
- Q: What is the difference between a photovoltaic cable and an ordinary cable? What is the structure of a photovoltaic cable?
- The structure of the PV cable is shown in the table. The difference between the ordinary cable and the PV cable is analyzed: The common cable can be seen from Table 1 that the conductor and the PV cable used are consistent. ordinary cable insulation and sheath can be seen from Table 1 different from the photovoltaic cable. Ordinary cable is only suitable for use in general environment. the advantages of photovoltaic power cable: high temperature, cold, oil, acid and alkali salt, anti-ultraviolet, flame retardant, environmental protection, photovoltaic power cable is mainly used for harsh environment, the service life of more than 25 years.
- Q: got 1 amp in the back,i want to add another amp at the front without a distrubuter,could i trail another power cable from the battery to the amp?
- yes but the battery might die out fast
- 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.
- The web page provides very thorough information and rigorous mathematical treatment relevant to the answer you seek. But it is just too much all at once to digest. So take it piecemeal, one bit at a time! First, you must realize that the sag of the cable is the single most important design parameter and strict attention to cable weight determines the optimal length. The equation of the catenary is the precise model but a parabolic approximation may work. (parabolic approx.) ymax = (3wl?) / ?√(64EA) P = wl?/(8ymax) Where ymax is the maximum sag l is the unstretched length w is the weight/unit length E Youngs modulus A Wire area P axial tension the curve is a parabola, which is a good approximation if the depth of sag is no greater than 1/8th of the span. Use the second equation to derive the induced tension P. H:=WL?/8S S:=WL?/8H L: distance between support S: Sag at mid-span H: tension (horizontal component of tension) The tension depends purely on the loaded geometry and the weight per unit length.
- Q: The computer is a Hp compaq.So I took the connector out of the computer but left it in the power socket.When I tried to reinsert the connector I hit the metal back panel of the computer and it made contact so I was wondering what is the part(s) that is likely to be broken?I want to know it so I can replace the damaged parts.Thanks in advance of your help.
- The power cable should have enough rubber/plasitc to stop contact with power supply directly unless you seen a spark I would try the a different cable. Is the power supply turned on? If it did spark and is turned on try swapping the power supply. Actually I missread, it touched the case itself so now you have to start swapping all parts starting with the power supply, then motherboard if that doesnt work. I hope you have some spare parks around. you could also take out the power supply and you will see a long 24-pin connector you can short the 1 green wire with a black one to see if the power supply turns on. The connector is a cable comming from the PSU not on the motherboard. And lastly each time you try to start the computer after swapping somthing only have the essentials to have it start. No CD drive extra HDD etc.
- Q: Interested to learn more about selection of Power Cable for Diesel Generating Sets. I have checked out a few websites, but they are all too complicated and ask too many questions. Would like to know if there is a thumb rule for this?
- Power cable size will depend on the output current rating of the genset. The conductor size shall be rated for carrying the maximum genset current contnuously and shall be rated for the voltage of the genset.
- Q: I am doing a test if the power supply.Can you have the computer on and plugged in with PSU out in the open, leave on the carpet ?Can you have the power cable plugged into the psu first and then try to plug in the psu cable into the mother board. Would this electrocute you? if you accidentally knocked over liquid onto the power supply while the computer is running and you touched the motherboard at the same time while you are perfectly grounded. Can this electrocute you? unpluging the psu connector while the computer is on?
- You can but I wouldn't I build PCs all the time in test configurations outside of the case, but I always have everythign on non conductive serfaces, ie wooden tables. Carpet would be a little to staticy for me. Your second scenario leaves two answers for me, both are no, but for different reasons. If I plug a psu into a motherboard with power allready in it, I could short out the motherboard or worse yet shock myself. Also, I don't want to plug a power cable into a psu without any load on the device, doing so can and will fry the psu. depends on the liquid, if it is dionized water, you can turn the pc off dry it out and may be lucky enough not to fry your system. if it is soda,tap water, or salt water of any kind, don't touch it. I don't care if you THINK you are grounded, even if you were, the current would still flow through you, and if you pulled away, out of sudden suprise, then you would get electricuted, not good. Unbluggin the power cord from the powersupply will not be the biggest problem, unless you have very sweaty hands and the air is very dry. Just don't play with electricity
- Q: Hey guysA 6mm power cable can hold up to 25A, but, if a product draws a maximum of 4A, in theory, can this 6mm be reduced? If so, by approx how much?Cheers, much appreciated!! :)
- Your wire has to be matched to the circuit breaker. If you have a 15 amp breaker you need #14 wire. Otherwise you could overload the wire and burn it out and the CB wouldn't blow.
- Q: The only thing that im worried about is that my PC power cable has three little slots where you plug it into the brick and my brick only has 2 slots, th cord still fits and powers up my xbox 360 but im just worried about it quot;fryingmy new system. Thanx
- Don't do it. The power brick is what powers the console and you need it to properly run it smoothly. Just get a power brick. If you don't have one, go on OKorder.
