Product line: VCV/CCV


 


Metallic screen/sheath: Option 1) Welded corrugated aluminum sheath


                                    Option 2) Extruded Corrugated aluminum sheath


                                    Option 3) Copper wire + poly laminated sheath


 


Outer sheath: PVC, MDPE, HDPE, LDPE


 


Characteristic of Use:


  1. Allowable max. long-time operation temperature of cable conductor: 90°C

  2. Allowable Max. short circuit temperature of cable conductor (max. sustaining period not exceeding 5s): 250 °C 

  3. Allowable Min. bending radius when laying cable, generally 20 times of the cable diameter


 


Main Cross sections for 127/220kV Power Cable:


400mm2, 500mm2, 630mm2, 800mm2, 1000mm2, 1200mm2, 1400mm2, 1600mm2, 1800mm2, 2000mm2, 2500mm2

Q:Is 8awg power cable enough for my sound system?
1. We can't answer without knowing more about your amplifiers. 650w 4 channel doesn't tell us anything useful, because the power rating may be a peak number that's only good for marketing, and you didn't tell us anything about the monoblock amplifier at all. Give us brand and model numbers and we might be able to help. 2. If I split that to use it on both amps, it would end up at 16awg going to the amps ....no. That's now how it works. (I'm not sure how you envision splitting the wire to make two wires that are half the size; are you cutting it down the middle with a razor?) You can use a distribution block to connect both amplifiers to the same main power wire, but you don't have to go to a smaller wire out of the d-block: you can run 8-gauge wire from the battery to the distribution block, then more 8-gauge from the d-block to each amp. 3. Even if you did cut the 8-gauge wire in half, a wire half the size of 8-gauge isn't 16-gauge. It's 11-gauge. If you put six 16-gauge wires together, you'd get a wire that's a little smaller than 8-gauge. Please edit your question with the brand and model numbers of both amplifier, along with the estimated length of the wire run (ie, how many feet of wire do you need to go between the amps and the battery?) Then we can tell you what gauge wire you need. Edit: thanks for the update. Based on the information about your amplifiers, I don't think you should run both of them from the single 8-gauge wire. I'd switch to a 4-gauge dual amp kit, or you can buy a second 8-gauge kit and run each amp with its own power wire to the battery rather than sharing a single wire.
Q:How does a laptop power cable work?
i could take it decrease back and characteristic them replace the device board. you're able to be able to correctly be properly on your thank you to frying it out for one, and a pair of, i does not have confidence that board because of the fact that now there is probable actual harm to it. extra useful to swap the whole board if below guarantee and it may desire to have a socket soldered on it already. If this is not below guarantee, this is an costly restore, value of the board could properly be $3 hundred+, exertions, one and a a million/2 to 2 hours, could properly be $one hundred fifty minimum to $2 hundred. an entire of $500, that could get a clean laptop in case you seem not straight forward adequate you're transforming into to be considered attempting on the place to circulate from here. If it approaches $4 hundred to repair, i could get a clean laptop. extra low priced, swifter and extra handy interior the quick and long-term. the recent it is straight forward to have a guaranty for if this occurs returned, the producer has to repair it at no value to you.
Q:Does voltage change if you split a power cable?
No change in voltage.
Q:high effency double shielded transmission power cable?
What is your question? Does such a cable exist? Probably but you'll have to be more specific. High efficiency = low loss or low resistance per foot? Double shielded = is the shielding (in dB) critical? Transmission = What frequency, 60 Hz, 1 MHz, 100 MHz, ? Power = Watts, KW, MW Is weight or cost important?
Q:Can I use speaker wire for power cable in a small amp?
nope dont do the rooky mistake and burn up the wire dnt be lazy actually get power wire
Q:Which has, know the power of the electrical, choose the cable formulas. And explain it
Is the interference signal line can not go with the wire,
Q:what causes cable fire?
a power surge can definitely cause a cable fire. but i believe insulation failure tops that, in buried cables in particular. and insulation failure is prompted more often with cables that come in direct contact with the earth, rather than those that may be run through piping, deterioting the insulation even faster. of course if the cable is damaged by digging, that could start a fire as well.
Q:How to setup the Power Supply Unit cables in my Intel i3 PC?
CD/DVD drives and hard drive all use the same power connectors (multicolored), so plug them in whichever way you want. There is no specific order. Don't remove any ribbon cables, and if you wish to have a floppy drive, the power cable is slightly smaller than normal ones. Commonly, fans can be plugged in to any port on the motherboard as long as they reach without straining the cable. They can only be inserted one way and are likely three-prong so it should be easy. The numbers on your cords don't matter.
Q:A network cable must cross a power cable. What can be done to minimize the amount of EMI?
Use okorder.com/ You would need two (one for each side of the connection)
Q:I lost my power cable for my Ipod Shuffle 2nd Gen, can I use the 3rd gen shuffle power cord for the 2nd gen?
My first, a 4th technology iPod Nano (8GB), became a Christmas present whilst i became sixteen - i'm now 23 and it in simple terms crapped out on me some months in the past. So, as long as you're taking good care of it, it may final a minimum of seven years! i will by no skill purchase yet another variety - my husband is exhausted via my seek for any such particular MP3 participant yet, i'm telling you, Apple is the superb thank you to bypass :)
