3. the power cable's characteristic:

3.1 long time operating temperature for cable conductor is 90 degrees.

3.2 the highest temperature of the conductor in short circuit (no longer than 5 seconds) in not more than 250 degrees,

if a joint is in the cable, the temperature of the tinning welding joint is not more than 120 degrees, compressing joint not more than 150 degrees and electro-welding joint not more than 250 degrees.

3.3 no drop in limited provided there is full mechanical tention when cable is laid. It si forbidden to lay cable in iron-pipe or to fix cable by circling around the cable with iron materials.

3.4 being laid, the minimum temperature of the cable shall not be lower than zero degree. In the case of lower temperature, heating measures shall be taken.


We can also supply the OEM and customized products according to your request

Q:Is it safe to jump a 12v power cable from one amp to another amp..help!!!?
its safe but its better to run 2 separate wires due to you are wanting to use more power and one wire has a max load that it can handle...you run 2 and you will have more power to each amp
Q:What kind of power cable would be suitable for my lcd monitor?
notice the info to the left of the port this is importent take this info with you when you look for one of these
Q:When i want to connect two SATA hard drives do I need some power cable on slave or just to connect it with sat?
Of course you will need power, how is it to run without it?
Q:My power supply cables won't disconnect from the hard drive, cd drive, ect? HELP!?
there isn't any other way......just hold the edges of the cable(tip of the cable - the black part ) and pull it out(pull it harder till it comes out)......dont worry you wont damagae your hard disk by doing this
Q:What amp rating fuse do I use on the power cable for my Belkin TuneCast II?
Those transmitters are very low amp draw... as you noted 0.5 amps, which at 13 volts is about 7 watts of power... and even that sounds high for a portable electronic FM transmitter. With that little power, you probably have a faulty unit for a fuse to blow. I assume you are using an aux 12v power source in your car and the (cigarette lighter) adapter that came with the transmitter. Now most adapters are not fused, but yours might be, and you could open it up and just see what the number on the fuse is - probably 2.5 amps max. Radioshack carries replacements for those small fuses. Considering that the car's fuse rating on most aux power sources is about 15 amps, your transmitter could not possibly draw that much unless there were a problem. The problem may lie in the aux power socket or in the adapter itself. I'd start by trying something else with an adapter - such as a cell phone charger. If plugging that into the same socket blows the fuse (in your car's fuse panel) then its probably the socket. If however it works fine, then the problem lies the adapter on your transmitter; which = return that and get a new one. I have seen many adapters with bad design that shorted easily and blow the car's fuse. Pray that its the adapter and not the socket.
Q:Why is an aluminium and iron mixture used for power cables ?
Aluminum is a good conductor that is also inexpensive and lightweight. Those are excellent properties for overhead power cables. Unfortunately, aluminum does not have the greatest tensile strength. So to provide strength to the cable, some iron (in the form of steel) is used as well.
Q:What is the meaning of "cable tray: 200 * 100 middle strip" in electrical engineering
Two should be phase line, generally in the three-phase loop corresponding to the color: A phase is yellow, B phase green, C phase red, neutral (that is, zero line) for the blue. If only in the single-phase loop only red and green when the default is red for the phase line, green for the zero line. But not necessarily, some electricians do not follow the requirements, the specific you have to use the pen to know what the
Q:How to hook up power control cable to factory deck?
attatch it to acc power on the back of your head unit, unless you have a chevy or gm newer than 2002 then use the switch method
Q:Where can I purchase a power cable for our Toshiba Equium laptop?
It is possible that your cable may have some broken wires inside that are causing your problem, or it may be the board as mentioned above. The board that is being referenced is the power connector inside your laptop and it's connection to the system board. What can happen is the electrical connections (solder joints) from the connector to the board become broken/loose and you have an intermittent connection. I have re-soldered these for friends when theirs go bad, otherwise a replacement system board would be required. I have also seen where the small leaf spring contact inside the connector becomes flattened and has poor contact as well (if this is the type of connector you have). You could check this with a good light and look inside the hole, there should be a center pin contact and a leaf contact along one side that should come down about halfway into the hole to the pin. To test where the problem is, connect your cord to your laptop, now hold the connection very still at the connector and wiggle, twist, push, and bend the cable at various points to see if the light at the front of the computer goes on or off. Now also test the plug at the computer by carefully moving it up, down, around in various ways to see if the light goes on or off. Wherever you find your problem is where you'll need to fix. If it is the power cable, yes, you should be able to buy a replacement. Try Toshiba's website or google the numbers you have to see what turns up. Hope that helps explain things better. Best of luck.
Q:Does ATI HD2600 Pro require to connect to the power supply via a power cable??
it might if so the plugin looks like a floppy drive plug four pins if you got the card new and it has an adaptor you will have to use it most ati cards that have external power syncronize with the hard drive .
