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;
4. To replace copper bus bar with small or medium capacity in various places.
III. Standards of the cables
IEC 60502 Rated Voltage 1 ~ 30KV extruded insulated power cables and accessories (International Electrotechnical Commission standards)
GB 12706 Rated voltage 35KV and below Copper core, Aluminum core plastic insulated power cable (National Standard of the People's Republic of China)
JCS 376 branch cable (Japanese Electric Wire Industry Standard)
General Rules for JIS C2810 indoor wiring electrical connection pipes (Japanese Industrial Standard)

Types of the cables:
Standard main cables and branch cables are all low-voltage power cables with XLPE or PVC insulation materials (IEC, GB, JIS, BS ... ...), and PVC materials covered on the outer side. Generally, the main cable is single-core or twisted multi-core cable (cables with two to five cores), the branch cables are single-core cables, and may adopt a fire-resistant, flame retardant cables in accordance with the requirements.
Their structures and types are as follows:
No.

Q: I have an ASUS G1SN-X1 and my laptop was working normally while plugged in. Then all of a sudden it stopped charging the battery. After it stopped charging the laptop was running off the remaining battery power. The battery eventually runs out of juice but now i can't turn on my laptop because the power cord won't charge even though the power indicator light is on on the power cord supply. I even took out the battery and just left it plugged in but still wouldn't turn on. Any suggestions on what the problem could be and how to solve it?
Seems to be a short circuit. This is a common problem with Laptops, including Asus Laptops. I've had Dells, Asus, Lenovo, and HP laptops and each laptop's power cord has broken at least once. Unfortunately, you're out of luck. You will need to buy a new power cord, which could run you anywhere from $15-60, depending on the vendor
Q: This is a self built computer. When using it in a different room, it functioned normally. However, now that I've moved it to a new room, it would constantly reboot or just loses power entirely. With the latter, I would have to remove the power cable and hold the on button for a while before I could turn it back on. Also, when I shut it down, the computer would reboot by itself instead.
Most of times the issue should be occurring because some problem related to power. Do easier things first. 1. Use another power cable. 2. Get an extension form different wall plug and power your PC through it. 3. Bring the PC into previous room and try. When using it in a different room, it functioned normally. However, now that I've moved it to a new room, it would constantly reboot or just loses power entirely According to your above saying, I can guess something like this also, If the computer had faced to some shock while you're changing rooms, sometimes, these is a chance to occur these kind of problems because a shock can produce a loose connection. Remove the causing and check all the connections inside CPU such as Power, RAMS, Processor....... and all it's possible.
Q: I need to run power cables from 4 fans on my stacker 830 around the edges of the case and into the power supply for cable management purposes. The fans I currently have, have power cables that are around only 10 inches long. Any ideas?
Can you solder? If so, just clip the wires then splice on extensions. Add heat-shrink material, solder connections, shrink the material and you're good to go.
Q: I looked on 3 of my friends plus mine and looked at the cord that comes from the big block power supply thing for the xbox 360 and every one of them looked differant. Why is that?
The new Xbox360s manufactured since October 2007 have a 175w power supply, whereas the older original Xbox360s have a 203w power supply. This is because they have different equipment.
Q: what kind of power supply cable plugs into the hard drive?
Which okorder /
Q: i bought a video card off OKorder and i did everything but i don't know if i connect both of the cables to the power supply...i currently only connected one but do i do both…
If you don't have a six pin PCI-E connector, then chances are your power supply is not power enough for the card but if it is, you connect BOTH of the 4 pin connectors, no just 1
Q: at the end of power cable are 2 wires
I don't know what you mean by 302cm power cable. When it has 2 wires, one if usually the hot (power) and one is the ground (earth.) I don't know much else that'll help you, sorry.
Q: I want to order a small 100 watt amp and needed to know if it can get powered by the head unit by connecting it with the rca cables.. thanks..
The wattage of the amplifier makes no difference. A new amp will have a specification for the input sensitivity. This is how many volts from the source will drive it. The line level output from your head and line level inputs on the amp should work. Line level outputs will probably not drive speaker level inputs on an amp very well.
Q: Where can I buy a replacement power cable for my ps3? I can't find one anywhere.?
This is a pretty standard AC power cord - at least in the US. Most desktop computers use the same 3-wire configuration.
Q: when the power cable comes out, the laptop turns off simple as that! it wont work unless the power cable is plugged in and turned on, and its not that the battery is flat because i had it charging all day.so does this mean the battery is broken?if so what do i need to do?? any help will be greatly appreciated!!
I would look into a replacement battery. If the problem continues, then the laptop might not be charging the battery properly. This can be because of the power cord, the connection between the battery and the dock, or even just a short somewhere in the circuitry. If that happens I would recommend getting it serviced or replaced.
