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:Hi,1) Is spinning down of hard disk same as removing the power cable of the hard disk ? 2) Will the IDE cable connected carry power to the hard disk when the power cable is removed ?3) How do we spin down the hard disk manually ?
- 1) When you unplug the power cable, it spins down, because there is no power. In order to read data from the hard disk it needs to be spinning. When it is not spinning, you cannot read data from it. Some power saving systems will allow you set the hard drives to spin down after a long time that it has not been used, to conserve power. After that, to read from the disk it needs to be spun up, and that takes a few seconds. 2)No. 3) You cannot manually spin a hard disk, it spins at 7200 (some models 5400) rpm. That's VERY fast.
- Q:Hi. I have an iBook power cable and I was wondering if there was a way to adapt it so I can use it for my new MacBook Pro that uses a magnetic cable? Thanks!
- you could try but you could blow your the new computer so I wouldn't try
- Q:cables? Power strip? thanks
- i jus bought a 37inch =P wat u need depends on what u want. but u shud get a power strip surge protector!!!
- Q:I dont understand what it says about Peak and sustained power, also the cable says it needs 12v DC, and the power supply gives 650 watts. I don't understand any of this, can someone please explain this to me, and if this power supply doesn't work, please give me examples of ones that will work. Longest answer will get best answer.Thanks!
- That Xbox power supply cable is pretty cool! I've never seen those before. Ok, as for the power supply questions: Peak power is the maximum amount of power the unit can supply for a short period of time (a few seconds at most). A computer, during start-up, will use quite a bit more power than once it has achieved steady state. This is because drives have to spin up, semiconductors have to power up, etc. Once everything is up and running, the power draw drops to nominal or steady-state Sustained power is the amount of power the unit can supply non-stop. When purchasing a power supply, always give yourself leeway. If a supply indicates it is 650 watts sustained and 80% efficient (gotta look at that efficiency!) then it can supply 520 watts of power continuously. Even at that, I wouldn't want to run it past 450 - 475 watts continuously. 12v DC is the high rail on a power supply. Different parts of the computer require different voltages to operate. Drive motors typically need the 12v DC, where as memory needs less than 3 volts. A computer power supply has different rails or supply wires which supply the following voltages: +12 volts DC, +5 volts DC, and +3 volts DC (there are some others but those are the key ones). I don't know what the power requirements are for an Xbox 360, but it obviously needs the 12 volt and 5 volt DC rails to power it. Anyway, the power supply you've listed above is more than adequate.
- 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:What is the difference between a photovoltaic cable and an ordinary cable? What is the structure of a photovoltaic cable?
- . soil buried pipe, including weak and fire, should be thick-walled galvanized steel pipe, that is, SC series of steel pipe, the best size is not less than SC. weak professional, decorative professional now basically use thin-walled galvanized steel pipe, that is JDG series steel pipe
- Q:I just recently bought an amp from my friend. It is a fender frontman 15 w amp. I think it is one of the ones that comes in the strat pack or something. anyway, she didnt have the power cable for the amp that plugs into the back, and i kind of need this. does anyone know where i can find one or buy it. I already looked at fenders websight. anything would helpthanks
- all i can suggest is try OKorder or your local music store, OKorder can be tricky because you could get one that gives distortion if it is not new, but if you are desperate, then OKorder or order one from your local music store.
- Q:i have a sata hard drive that i wont to put in an older mb. i purchased an adpater but i do not know what the larger sata cable if for. there is no place to put it.
- One cable is the power cable and one is the data cable, just like IDE drives have two cables for the same purpose. You will need to have a 4-pin molex to SATA power cable connector and also a hard drive controller card with a SATA port on it for you to be able to connect the drive. If you don't have both of these, you won'e be able to hook up the drive at all.
- Q:I need a replacement tip/end for my laptop power cable- specifically, the small cylindrical metal-and-black-plastic bit that plugs into my laptop. The cable and black box part of the cable are working fine, but the tip has bent and I need a new one. I'm having trouble finding any on OKorder or elsewhere because I don't know the technical term for the component to search for. Can anyone help?
- this is the ac power adaptor , go on the web site for your particular make of laptop check the spec for it.it should be in the part that lists accessories.
