I. Characteristics of the cables
1. Using factory prefabrication methods can substantially reduce the site construction labor intensity and shorten the construction laying time;
2. Use of cables can guarantee great length and bending property, and greatly facilitates the construction in a complex place;
3. Use of cables reduces the laying space, and cables can be installed together with gas and hydraulic gas pipelines;
4. Their reliability and reliability can be fully guaranteed, for the cables are manufactured in the factory,
5. Sub-branch parts should use high strength sealed joints, which are waterproof and have properties of moisture protection, long-term maintenance and free for repair;
6. Because the cables are directly connected with households with no need of maintenance and repair and with easy and simple construction, the cables can produce significant comprehensive economic benefits.
II. Usage of the cables:
1. To be used for high-rise building;
2. To be used for disaster prevention equipments;
3. To be used for tunnel lighting and disaster prevention equipments;

- Q:Ok so I was doing something stupid just now. Cuttiing a power cable that connects to the tv. Halfway through to cutting it, the wire explodes and hit my face o,o. So quickly, I turn all of the switches off and run to wash my face. I just wanted to know whether it's ok to turn all the switched back on cus I'm literally in the dark right now. And will there be any damage to my face since the wire explodes in my face?
- Everything will be fine to turn the switches back on, but you must unplug the cord you were cutting first. If not, you'll hear another loud pop as the breaker switches off. Unplug the cord, then turn the switches back on. Before you plug the tv in, check the cord going to it for burn or charring. If you do not see any, then stand to the side of the tv away from the screen and back, and then plug it in. Be careful. Unplug the cut cord first!!!
- Q:Should I call 911 if a frayed power line fell in my driveway?
- Call the power company. Make sure you do not touch the line. Do not allow your children or pets near the line. There is nothing the police can do so calling 911 is not appropriate.
- Q:i just want to select the power cable but i m having some confusion that when we select single core power cable we take current rating of that conductor but if we say 3-core cable has 200A capacity then it means that each core has this capacity or it is the the capacity of overall 3-cores
- Current ratings for conductors are based on several factors including conductor type (Copper, Aluminum, other), insulation material (thermoplastic, rubber, asbestos composition), ambient temperature, length, exposure to weather, and numerous other factors stipulated by the NEC or local Code. The ratings are usually given for a single conductor in free air. Mulitiple current carrying conductors which share a conduit, raceway, or any other enclosure must be derated appropriately. See the source below for Code reference and rules of thumb.
- Q:When doing competition, is there a rule where your battery in the back can't be bigger than the one in the front? Are Monster Cables as good as they perceive to be???? I.E. their 400 series cables that are wound in different arrays to optimize each frequency out put? Can a Power cable actually provide more efficiency if constructed right, once again, their 400 series?Subwoofers being 1000 RMS but only getting 500, will running them at their RMS make a significant difference?
- I'm not 100% sure but I think that doesnt matter. What matters is the amount of batteries you have. There is a significant difference between 500 to 1000 watts. But it depends on what enclosure is being used that makes it louder...much louder in some cases.
- Q:I'm about to order everything to put a new sound system in my Jeep Wrangler and I've been planning the locations to run new wires and cables. I got to looking at the area's where I could run the power cable for the amp and have come to 2 conclusions. I could either drill a hole in a very difficult to reach but hidden area behind the dash and try to hide the cable on the interior of the Jeep all the way to the rear where the amp is.. or, I could run the cable inside the hollow frame rails (which have many pre-drilled holes to slip the cable in and out of) under the Jeep and then just drill a hole to the interior in an easy to reach location near the amp. My only concern is that the cable's insulation will breakdown and crack prematurely due to exposure to water and road salts.. is this a real risk if I run the cable on the exterior of the vehicle? Or will the cable hold up just as well as any other cable such as those in the engine compartment? Thanks for your help!
- Keep it inside. Run it under the sill plates and carpet (or rubber flooring). If you put it outside and it wears through the insulation (for what ever reason, elements, chaffing) it could cause a serious problem, even a fire, as it would be directly to the battery.
- Q:my cable often gets unplugged soo im really worried that i may loose 280 dollars?
- Yes, power failures can be associated with voltage spikes that can cause damage to the PC and its components. Buy a decent surge protector or extension cord with a built in surge protector, and use this to power your PC.
- Q:I bought this graphics card tonight, and went to install it on my new Dell PC and while the card itself is powered by a 6-pin, I don't have one on my power supply. Is there an adapter I can use? Or will I have to go buy a new power supply for a NEW computer..?
- Depends - what are your system specs? Impossible for people to help you when we don't even know what hardware you're running. Don't ruin your new graphics card by putting it ; 1. On a power supply without enough wattage to handle it, and 2. On a power supply that didn't come with cables for a graphics card. Chances are you should invest in a bigger power supply. I would recommend at least 550w for a GTX550Ti. I recommend Corsair and XFX power supplies, as well as Seasonic.
- Q:Need the cable you plug into your outlet and it's plugged into the back of your power supply on your computer. My computer is for gaming and is very modern so I need one that wont melt and can handle everything. Anyone know of anywebsites that I can order a high quality one from?
- all you need is a bog standard power lead. The power unsit runs off mains voltages so a 500W supply uses only 2A (ish) (if on a 220V system) and 4A if on 110 (approx)
- Q:Is the ribbon cable the data cable and the wires the power cables?
- Trace the cord with your hand, if it goes up to the power supply box way up. its a power cord. and the rest are data cord
- Q:The power is a 24 pin and does not have a green wire. It has a grey, 6 red, 3 blue, a yellow , an Orange, a purple, a dark blue, 8 black, and a brown
- MATERIALS 1.) power supply 2.) power cable 3.)paper clip Step 1 Plug in the Power Cable to the wall, and then into the back of the Power Supply. Make sure the Power Supply is flipped to 1 and not 0. I like to remember 1 is for power because 1 looks like I, and I have ADHD. So I always haves me some powers. 0 is like O which is like my OH face. Then I am drained of power. Step 2 Take the paper clip and bend it into a 'U' shape. We want the two ends of it to be next to each other, or relatively close. Step 3 Now we are in the final step. Locate the Green wire on your PSU. There should only be one Green wire, whether you have a 20 or 24 pin power cable. Alright, we found it. Now we get have to find a Black wire on your PSU as well. There are a few, but we should be fine. Finally, take the paper clip and insert one end into the Green wire and the other end into any Black wire. And there we have it. Your power supply is alive and kicking. Again, this is a good way to test fans for functionality, CD-ROMs, and Floppy Drives. Almost any component that will plug into this is fine. I would not advise for your hard drive in case of data loss, but if it's a questionable hard drive (why else would we test it?) then you I'm guessing you don't care if it has anything on it, or it's too old to matter.
