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: my tv is mounted on the wall, and my friend came round and we tryed to plug in his ps3 and we knocked the main power plug from the tv.we have fiddled about for around an hour looking for wer it came from and need help before my mam gets back!
- It's in the back, near the main power switch but it's up and under. Look from the bottom up and you should see it
- Q: What is the safe carrying capacity of the power cable YJV22-10KV-3 * 400?
- It is best not to use this, because you have no way to test the signal line. There are special 10 line 8 line terminal telephone switch patch panel
- 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: I have my old 350 power supply cable but i got a new 520 one. do i have to use the defuly 520 power suppl cable? i use my old cabbke
- The cable merely supplies the power to the PSU. You're confusing the wattage of the PSU (350/520W) with the supply voltage (110/120/240v). The cable will work perfectly with either one?
- Q: can you use a standard molex power cable on a SATA HD or do you have to use a SATA power cable to power it?
- depends on the drive.. sometimes a drive will have a 4 pin molex and a SATA power plug.. most newer drives will be SATA only though
- Q: a. the potential difference between the forward and rear feet when the bear crawlsb. the potential difference between the bear and the cablec. the coulomb force between the bear who obtains charges when passing by the cable and the cabled. none of them
- a. The bear has completed a circuit between the cable and the ground. Electrical current takes the path of least resistance and will flow through him rather than through the air which has a low conductance. Since the bear has a resistance the electrical energy will do work (the energy it takes to move electrons from one potential to another) to over come his resistance and some of the energy will be transferred to heat. This is why people who are electrocuted will burn from the inside out.
- Q: On my PSU I have two PCI-E 6 pin cables. I have looked at the motherboard and saw there is nowhere to plug it in and my motherboard manual says of no slots for it but I do have two PCI-Express slots. Do they plug into the cards themselves or something?How do I use the PCI-E power cables?
- PCI-E power cables are used for add-on graphics cards that connect to your motherboard. These cables are technically supposed to connect to those cards, NOT the motherboard itself. You don't have to plug in every cable that comes with you PSU anyways, just leave the unused ones aside, and they wouldn't be provided with electricity
- Q: my laptop power cable is pluged in and turned on but it fails to charge or power my laptop but its in properly and sumtimes works .. any help?
- ok....this might not be you power supply cable.. this may be a problem with your powerjack in your laptop, if that's loose, then it won't recieve any power from the cable...it will randomly though..i had the same problem a few months ago, and a little solder job will do the trick! take it to a good local repair guy (or me if you're in the uk hahaha)... and have the power jack resoldered.. try your power supply on another similar laptop to make sure it's not that..but generally speaking..once a power supply's fried..it won't work randomly...all it is, is a transformer and a converter... it would make sense if it was the power jack loose or has a faulty connection to the motherboard :) hope this helped!
- Q: I need to change a cable that goes from public power lines to power meter because its skin/protecting shield is peeling off. What happens is that I need to fix this issue as soon as possible but do not know what kind of cable should be used for repair. I would greatly appreciate your help. Thank you!
- What did the electrician say? This is not exactly a DIY project, because it requires inspection and possibly permits. You cannot connect this yourself. The size if the wire is related to the material, distance, and power. It may also be related to local practices. The old 60 amp service entrance is illegal, so you may have to upgrade to 200 amp which would be way different for wire size. An electrician will know the codes relevant to your situation. You can probably get the wire at a home improvement or electrical supply house but the electrician will have to make the connections. Plus, it keeps you from frying yourself or the electric company from pulling the plug.
- Q: What is the difference between the power cable yjv and the vv cable? In the use of what to pay attention to? What is the difference between selection? Online ~~~ more
- I have to integrate a graphics card, you buy a separate graphics card is really a waste of money now I also listed, showing a lot stronger than the 2100 performance, and the market in the low-end discrete graphics upstairs you upstairs a lot of results Even a display did not give people with the price exceeded
