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 wasnt thinking and put the power cable in my mouth and then pressed the tip on my tongue and got electrocuted... it still hurts a little.. am i going to die
Yes. Yes you will. It might take years, and your doctor might call it something completely unrelated - like cancer, old age, or a car wreck. But this is what really caused it.

It does happen quite often. Mine got damaged for no reason, guess is the weak link in your mac
Q:This is all I got in my PC, where is it?
That's a SATA drive - you're looking for a black connector, something like the one connected to the drive. If you don't have one (the white one that looks like it's touching the back of the drive in the picture is a PATA power plug), you can buy an adapter, so you can power the drive with the PATA plug.

If your talking about the power cables from the power supply to the motherboard those are fairly straight forward. It is a 20 or, 24 pin connector. Usually along the edge opposite the external connections for the motherboard. Although, the placement really depends on the manufacturer and, could even be near the middle of the board. They are keyed and, you can not plug them in incorrectly. As long as you don't force them into the slot. If your speaking of the wires from the case to the motherboard that is a little more difficult. P3 and, P4 motherboards usually have a keyed connection that simply plugs in. Other boards have markings on each of the wires corresponding with it's connection. The one thing that is the same for every board is that the two black wires must be side by side. If you've never done it before you should have labeled each wire and, made a diagram of their placement. Your best hope short of taking your computer to the local shop is to try and, find diagrams for both your motherboard and, the case.
Q:I want to switch to cable phone (indeed, that Triple play service offered by companies as Optimum or Time Warner). When power fails, you dont?expect to have Cable TV or internet, but phone service is different. You really need it all the time. Some people told me outages affect cable phone service. I?m very concerned because some neighborhoods in my city have had blackouts recently.
With every day pass, our country is getting into more and more trouble. The inflation, unemployment and falling value of dollar are the main concern for our Government but authorities are just sleeping, they don’t want to face the fact. Media is also involve in it, they are force to stop showing the real economic situation to the people.
Q:My old card only needed one of these cables. but my new 4870 will need two. can i just use a IDE-to-PCI-e power cable? its only got 3 wires out of the 6 though. does this matter?
You okorder /... It takes two 4-pin PSU molex connectors and converts it into 1 6-pin PCIe connector. Make sure your PSU can supply the necessary amps on its +12V rails, and if you got a PSU with multiple +12V rails, you need to make sure you got the load spread out among different rails to avoid overloading one rail.
Q:Can i leave my laptop on the whole day and just turn it off at night? It has a standby mode but i dont no if thats resourceful. Also it has sleep and hibernate. Will leaving the power cord in be bad?
My laptop barely goes away from its power cable mainly because I don't travel that much. I've had my laptop for a year now, it's completely fine. Just turn it off at night so you don't run up your electricity bill dude.
