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. | Cable Description | Type | |||
single core | three cores twisted type | four cores twisted type | five cores twisted type | ||

- Q: Is it safe to connect the case fans in line with the hard drive, or should I use a separate power cable?
- If it's a newer motherboard and case, there should be jacks on the motherboard itself for the fans . It should be safe yes. There are minute reasons why you might not want to, but the odds of interference or power supply variance are quite remote.
- Q: What I really just want to know is the equation and basic concept on how to determine the optimal length of power cable needed to connect two poles while knowing only the linear density of the cable.It does not matter how much sag is produced because of limitations due to the strength of the power cable.
- The web page provides very thorough information and rigorous mathematical treatment relevant to the answer you seek. But it is just too much all at once to digest. So take it piecemeal, one bit at a time! First, you must realize that the sag of the cable is the single most important design parameter and strict attention to cable weight determines the optimal length. The equation of the catenary is the precise model but a parabolic approximation may work. (parabolic approx.) ymax = (3wl?) / ?√(64EA) P = wl?/(8ymax) Where ymax is the maximum sag l is the unstretched length w is the weight/unit length E Youngs modulus A Wire area P axial tension the curve is a parabola, which is a good approximation if the depth of sag is no greater than 1/8th of the span. Use the second equation to derive the induced tension P. H:=WL?/8S S:=WL?/8H L: distance between support S: Sag at mid-span H: tension (horizontal component of tension) The tension depends purely on the loaded geometry and the weight per unit length.
- Q: I was playing Call of Duty Black ops when i looked down at my mess of cables. I have a lamp the also plugs into the same power outlet. When i looked down my lamp(that i leave on 10 out of 24 hours of the day) had this white stuff on it. I didn't think too much of it at that time but i looked at it again later and i was nervous that it could be dangerous. Anyone have any idea's as to what it could and if it is dangerous? Will it continue to spread? I don't want my ps3 to be destroyed. I looked on the internet and it sounds like Battery post corrosion. Not sure though. Thank you very much.
- dont use it unless you want a fire, get a new lamp from IKEA for $8. its better than burning your house down lol ya its some sort of corrosion. dont risk it bro
- Q: Wire and cable manufacturing process (to be detailed)?
- Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
- Q: I've had this laptop (Dell Studio XPS 1640) for about two and a half years, and I've been through three power cables. The first one was a no-brainer, since the end was wearing a lot and you could see the wires. The past two have basically just stopped working for no obvious reason. The blue light on the end of the cord still lights up blue, but my computer says plugged in and not charging. I just bought a brand new one less than four months ago and it's worked perfectly until this past week. Has anyone else been having this problem with similar laptops? And if so, is there anything I can do besides wasting more money on a new cable?
- I would suggest your take your adapter in to your local computer store and they can check it out. If your adapter is working but your still not getting current then the problem is inside your computer and it will need to be sent for repairs... Source(s): CompTIA A+ Computer Professional
- Q: all i found was four power cables and 1 was for the floppy and the other 3 were the 4 color cable how can i power this 3rd hd with unplugging my cd drive?
- goto the computer store and get a power plug T adapter or make one yourself u know cut, splice and tape or saulder just make sure it is in parallel yellow to yellow red to red etc...
- Q: Indoor dry bag type steel core power cable terminal what is the meaning
- You ask this is too professional, it is difficult to answer, to ask the air conditioning technical staff Caixing.
- Q: There is no load in the middle of the problem added: the laying of the laying, and now the longest cable can do more long
- Pipe protection cable to wear metal hose, metal hose and galvanized pipe to use metal lock connection, the connection can not pull the light pull on the line. If there is no metal hose or no metal lock, in the pipe when the pipe toward the cable to the appropriate bending, preferably in the mouth of the cushion cable skin, and then use the electrical adhesive tape sticky, sticky. After the nozzle cut with a polisher smooth grinding, the provincial scratch cable.
- Q: I bought a 9800 gtx card, and it needs 2 power cables connected to the power supply for it to work. It's a monster card. My power supply has one pci express power cable only. Will I need adapters to plug into my power supply?
- The adapter must have two of the four pin Molex connectors. It uses three of the wires, in the four pin Molex connector. (3 wires x 2=One 6 pin PCI-Express power connector)
- Q: where do i put the wire through from the inside of the car to the battery located under the hood?
- definite you could. you will might desire to purchase an o.e.m advantageous terminal so which you would be able to connect all the skill leads. you will possibly be able to desire to be extra perfect off in basic terms going the dist block direction. A 4 guage to 2 or extra 8 guage block may be discovered on OKorder for under $10 shipped quite easily.
