Q:cable laid in the GI trays and temperature is 30 digree centigrade

There is no definite safe formulas for your cables because it depends on many factors like what conductor . what insulation, how many cores ,what is your load , where is your load and ambient temperature and so on. The best guidance will be from the particular manufacturer who would provide the tables under various conditions as above.

Q:Cable zc_y v22 what does it mean

No problem with the copper, the home is no problem as if you take a twisted pair as a telephone line KVV with BV material, the process is not much difference in the production

Q:The difference between the power cable YJY22 and YJY23 is in the outermost layer, one for the PE sheathed, one for the PVC sheathed. What is the applicable environment, and why? Question added: I have to ask is the difference between 22 and . not 22 and 32! Thank you for the answer. Learn more together

The bearing capacity of the square millimeter in the wire decreases with the increase of the wire diameter, for example, 1 mm square meter

Q:I have one Ethernet cable running to a WiFi antenna. The antenna is powered by the Ethernet cable, using PoE. I want to be able to plug the current cable into a hub or switch, so I can connect other devices (non PoE) like an Xbox 360 or PC, but I also need to maintain the PoE to the antenna. Taking the antenna off PoE is not an option. What kind of device can I use to split this PoE line into PoE and non PoE cables?

Well, most POE devices come with a POE injector which puts the power on the line. That box will have TWO ethernet connections one which goes to the antenna has power on it. The other is a DATA ONLY cable. (also connected will be the power supply) That data only is the cable that is connected to your computer! Put that to any switch etc it is just plain everyday ethernet!

Q:I currently have a 250 watt 2 channel power cord and a 500 watt alpine amp with 2 12 inch mtx terminator subs.i am continuously blowing blade fuses and i ended up buying a 680 watt power cable. Will this blow out my amp or do any damage or will it be all good and give the maximum power my amp can supply? (Without exploding) just wondering thanks!

no sir it will not, infact it may completly stop the problem, i would say to much current is passing through the wire, if the amp will accept the wire (even if its a tight fit) thats what your looking for. so to answer your question using the 680 watt wiring kit is just what you need and will be perfect, you could even get the 1200 watt wiring kit if need be, (assumikng you bought the schosche kit from walmart)

Q:I just finished building my shed, I put a 1 1/2 inch conduit under the shed coming up into the corner. I am now about to dig the 65 foot trench back to the house. I need to run power, not a problem. I want to run a phone line, a network cable, and a cable wire for my satellite. I say shed but it is 12 by 20 feet with an attic. Can I run these additional lines in with the power. I was thinking about using a run of Shielded cables for the network and one for the phone. For the cable some heavy duty quot;I don't know what thoughquot;. Will the power lines mess the data up on them? What will work for the three if any. If I need to I could run them in a new conduit, but that is not cheap!

First, contact the diggers hotline and let them know when you will be digging. They will come out and mark any buried lines with flags. Run the electrical in the proper, approved conduit (to code). Run the phone line in its own conduit. The network and satellite run together in their proper conduit. A few bucks extra is worth it when you realize that the interference on the television is caused by running them all together. Right?

Q:HiIs it advisable to run 110VAC cable from the sub stationa and 110VAC cable from generator (clean) in the same conduit ; one of them for lighting and the other for CCTV; the concern is if the one for lighting is not clean (not consisting of a pure sine wave or carrying interference) would that effect the power line of the CCTV and has an effect on the picture? even though both are 110VAC.the installation is over seas where the power from the station is not consistence.

if the two are not shielded from each other they will cause interference... run two seperate metal conduits,, or use shielded AC cable in the same conduit ,, ground the shields and the conduit!!!

Q:I left my power cable at my cabin, which is a few hours away. I don't want to replace the cable (I'll be going back anyway in a few days), but I need to use my laptop. So far I've tried an old laptop cable, but its to big, and a game system adapter, but it doesn't have enough power. Are there any solutions that don't involve me buying a new cable?

Do NOT play guessing games with this. If you use one of a higher rating or worse with reverse polarity input you will totally destroy the laptop.

Q:i have a 01 grand prix gt and i want to run the power cable to an amp , anyone know a good spot to run it?

I recommend running it on the same side as your battery. That way you won't have to cross all the way to the other side of the car. Also, it reduces the length required for the wire. If there is somewhere that you can life up (like a panel you can pull up on the bottom of your car, where the doors are), you can potentially hide the wire under that and run it also.

Q:Many of the complete amplifier kits, example rated for a 700 watt amplifier come with a 10 gauge power cable. Many of the gauge charts from the online car audio techs, would recommend a 4 gauge wire, but they sell the amp kits with the 10 gauge. I guess bigger is better, more efficient and safer for the installation, but I would expect them to add some * adjacent to the kit specs with their recommendation.
