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: I have dell optiplex 755 @ Q6600I bought a new graphic card, HD4850it requires 2 IDE power connections,but my computer has just SATA connections.I saw sata-to-ide converter in the internet,but in my country there isn't any store that sells it.What should I do ?
- are okorder /.... Look at the second to last picture, the small black 6pin connector next to the copper heatsink is what you need to use. I'm guessing that in thebox you got a 4pin molex y splitter to use in case you don't have a 6pin connector from your power supply. Put the 4 pin y splitter back in the box and look for a lead coming from the power supply that has the matching 6pin. Dell's have used the 6pin connector for a while.
- Q: I lost my Xbox power brick and was wondering if I could use a cable from my old ps3?
- of course not, they're made for a completely different system
- Q: i have a 12V battery and a y power cable. will each side get 12V?
- yes you will have 12V each side, why?..because of the Kirchhoff's Loop Rule.. delta V = 0 for any path in a circuit that starts and ends at the same point. google the Kirchhoff's Loop Rule for more detail
- Q: Explain why a bird sitting on a 400 kV power transmission cable is not electrocuted?
- Electrocution is created by the passage of electric current through living organs. A bird sitting on a 400 KV power line is charged at 400 KV but it takes a *potential difference* to cause current to flow. As the bird is only touching one side of the 400 KV line there is no potential difference across the bird therefore no current flows thru it. Hence bird isn't electrocuted.
- Q: Copper and Aluminum are being considered for the cables in a high-voltage transmission line where each must carry a current of 50A. The resistance of each cable is to be .15ohms per kilometer.A. If the line carries power from Niagra Falls to New York (500Km), mow much power is lost along the way in the cable? Compute for each choice of cable materialB. the necessary cable diameterC. mass per meter of cable Please correct if you see anything that may be offSolving for part a:Power = I deltaV, since deltaV was not given IR=deltaVso Power = (I^2)R = 50^2 x 75 = 187.5 kW lt;-- answerR= 75 since R= .15 ohms/ km x 500kmB) resistivity of copper = 1.7 x 10^-8 ohm m resistivity of al = 2.82 x 10^-8 ohm m R = (resistivity x length)/Areawhat do i use for R? is it the 0.15 ohm/km or 75 ohm?using the 75 ohm as R, I get that the radius of the copper wire is 0.0000361 m and the diameter is then 0.0000722.Am i on the right track?
- I think you went wrong with the length. If R= (resistivity x length)/Area, make sure you are using length as 500,000m as the units should be in meters, not km. R is going to be 75 ohms because you are considering the entire length. Then solve for area and radius.
- Q: I'm referring to the older models of both the PS2 and PS3, not the slim models.
- The USB adapter works for me. On some video games like Soul Calibur you are able to press the analog button previously the controller will initiate working, and it gets fussy some situations having to unplug it and placed it back in.
- Q: (above question) and can i use a fender strat guitar with this amp instead of a bass? and are there things i should know before using this amp?
- The power cable thing could potentially be a serious problem, since it seems the ground wire is lifted or missing. I'd definitely check this with a knowledgeable person if I were you. It may be as simple as changing to another AC power plug and connect the earth/ground wire. Do you need an extra preamp? No. Any combo amp have two amp stages built in: pre- and power amp. Adding and extra preamp is highly unlikely make the sound better. You will probably just add hiss and noise. This is not a great amp for playing guitar, although you won't ruin anything by doing it. Just plug yoiur guitar in and see if you like the sound or not.
- Q: Hey y'all , so I got this LG X120 Netbook thing and although it works fine when power supply cable is connected, it won't play just by getting supply from its own battery..also i tried starting it up with the power cable on, and after a few moments I unplugged it, and the screen went black-I mean the netbook was turned off by itself..any help with that? thanks
- lg has not got reports like these there might be sum internal fault in the hardware of the pc so u should try to exchange this or buy a lenovo 1
- Q: 1) How is the connectivity between 2# of 300AH battery and 200A Power plant made?2) Need to know the cable sizing between battery and power plant.3)calclation to arrive at the sizing of input cables, output cables and charging cables between battery and power plant4) Are charging and discharging paths same in the batttery? ie when load is on battery whether the load current flows through the same cable of charging ?5)A photograph of the system will make me understand the solution better
- even in spite of the undeniable fact that nuclear potential promises for the potential desires of the destiny, in spite of the undeniable fact that it's not a eco-friendly potential. The social value all of us could pay contained in the destiny outweighs the benefits of nuclear vegetation / nuclear potential, taking the teachings from our previous thoughts with nuclear plant around the international. having said that, more beneficial RD should be channeled into parts of wind, image voltaic, water potential technology. the foremost observe right it is determination eco-friendly potential. after all, we in effortless words have a million earth and that is sparkling to everybody that polluting it extra may in effortless words bring about killing ourselves and our destiny generations. in effortless words eco-friendly potential ensures our destiny generations' endured lifestyles in this one and in effortless words abode we've; Earth. As in all advancements, initial progression expenditures are severe yet as we strengthen and flow in the route of eco-friendly potential, there is continuously a tipping aspect the position eco-friendly potential will develop into economically plausible potential. apart from, how can human form commerce-off the price of arising sparkling potential adverse to the same old fact of organic detrimental environmental consequences of nuclear vegetation ? There could no longer be a interest of arising extra nuclear potential vegetation in any respect, contained in the face of fact of the risky consequences to the ambience. eco-friendly and sparkling potential should be pursued because the destiny potential answer for the destiny.
- Q: hello guys,how does a power boost cable works?what is the difference between a usb cable and power boost cable.
- It is simply a 2nd USB for power alone, it does not use both USBs to transfer files, just one, the 2nd is just for additional power to improve the performance of the hard disk
