Specific property for usage of 110KV~220KV XLPE high-voltage cable

Cable’s conductor highest working temperature is allowed up to 90℃, and overload when meet an emergency is 130℃ ,When short circuit (in ≤5 seconds) the highest temperature is 250℃
When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.
The minimum bending diameter:

Cable type Bending diameter	Metal sheathed
After laying	30D₀
During laying	40D₀

Cable type

Bending diameter

Metal sheathed

After laying

30D₀

During laying

40D₀

Note: In form, D₀ is a real test value to cable’s outer diameter.

4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent section) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4.

5. Allowed biggest lateral-press P, when cable is being bent

The single core cable is required P≤500kg/m.

P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.

6. Cable laying is not being restricted by drop.

Q:when you install a power cable you usually route it through the door seal and under the carpet. If there are existing speaker wires that go to your rear speakers, will the power cable create an interference?: General rule is to keep power wires and wires that run sound signals separte. I always run my power and remote wires on one side of the car and speaker and rca wires on the other side of the car.

Q:I have recently purchased a SAPPHIRE 100228L Radeon HD 3850 512MB 256-bit GDDR3 AGP 4X/8X HDCP Ready Video Card.: 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:Hello, i have a quick question, this card doesn't need PCI cables right?My power supply is 450 wattNVIDIA GTX 750 TI is the cardThank you: My GTX 750 Ti OC 2GB card does not need cables--all power goes through the motherboard to it.

Q:I just bought the 8800gt, but i don't have the cable to connect it to the power supply.So what cable do i need ??I found those but i am not sure: If you want to find out what cables you need there are two ways. 1. check the manual or guide that came with the device to see if it says what cables you need. 2. take the device with to a hardware or electronics store and ask the clerks there to help you find the right cables for you're device.

Q:my mom just ordered the kinect package for $149 but i didnt realise until after that i needed the extra power cable for the kinect controller (motion sensor thing)... and i dont have the $50 to get it either so if anyone has purchased this already does it come with the power cable or do i need to start trying to sell my xbox to upgrade to the slim?: the xbox slim does have a different power cable and a speical slot for the the kinect cable as i brought one the other day you would have to buy the new xbox slim i should think

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: The battery and power plant statistics do not enter into the calculations. I assume that the load is continuous, and the battery is to be continuously trickle charged. The power plant will have to deliver the load current and battery trickle charging current, at the voltage necessary to charge the battery. You will need to know the load current, the trickle charge current, the distance between the power supply and the battery (or load if you connect directly to it), and the voltage necessary to supply the load and trickle charge the battery. The voltage drop will be the total current multiplied by the total circuit resistance. this resistance will be the sum of the individual conductor resistances. As an equation, this is Voltage drop = total resistance times current in amperes. The total resistance will be the voltage drop divided by the current. Now you know how much resistance you can stand. The National Electrical Code in the US has tables showing the resistances of various sizes of wire, and how much current they are rated to carry. From these, or maybe from you wire supplier, you can find out what size wire you need. It will need to be large enough to supply the voltage and current, and have a rating for at least that much current.

Q:I live in the uk: Laptops each have different power cords, because they have different connections to the laptop itself, so there's no one universal power cable. However, you can easily buy generic powercords for your specific laptop that are cheap. Just go to a site like Amazon and search for your laptop name.

Q:i want to run a power cable from my battery from under the hood to my trunk for a amp that i want to power. i have a 94 mercury cougar. and i have seen it done under the car and through the firewall into the cockpit, if i want to run it through the firewall which way do i put it through? can someone send me a link to a pictured instructions? or just tell me how? thanx: Look for a grommet around the steering column or brake pedal. Using a screwdriver from inside the car, poke a hole and with a piece of coat hanger, tape your wire to it and pull it through towards the engine side. If you can't find a grommet, drill a hole and put a grommet in.The center of the grommet should slide easily over the wire and drill the hole the same size as the grommets outer diameter in the groove. The fuse should be no more tha 18 from the battery. _______ (sigh) Technically, running your RCA wires and power wires shouldn't cause any problems and can be dubbed a myth. However, a lot of people will disagree. For induction between power and signal wire to occur, a form of AC (with some current) must be introduced on the DC power wire. The signal throught the RCA cables, doesn't have enough current to do this. However..... One solution, if you want to run them together, is to have good shielded RCA cables and/or to separate the RCA wires and twist them (as in twisted pair wire, twisted pair wire is used in CAT3, CAT5 and CAT6 communication wire to eliminate noise/interference/induction). Another solution is distance, you don't have to have cable on both sides of the car as a 1 foot separation will do just as good.

Q:i have a cable modem that i lost the power cord to. i found another that fits but the output listed on the adapter is 12.5vdc. the modem lists +12vdc. can I use them together? i plugged it in and it lit up for a while but then went out but I don't really know how the modem is supposed to work if there's no internet connected to it.: first! are you sure the modem needs 12 V DC and not 12 V AC? Mine uses AC. OK, you can use a 12.5V in a 12V modem - the extra .5V is not a problem... Next, make sure the polarity is correct!! center pin is the correct polarity? If not, POOF! You will let the smoke out. Have you considered that the modem is bad and the power supply is not the problem here. If the modem is bad, you may have killed the supply you plugged in.

Q:even though it lights, its not so bright. its little dim but cpu is not at all turning on, its silent...: CPUs don't 'light'. nothing ain't - nothing is not - everything is (that's what you really are saying). The power light may 'light', but if there is no CPU function, no power is going through the CPU. Probably a bad PSU (Power Supply Unit). Change it (cheap).
