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 | ||
1 | PVC insulated PVC sheathed branch cables | FZ-W | FZ-W-3 | FZ-W-4 | FZ-W-5 |

- Q: Suppose load is 100KW, length 50m, how to calculate cable size. If we know current Is any easy mathod to calculate cable size.
- rated current = 200 amp
- Q: Hi there - I had a Mr Bean moment when hooking up my DVR and camera during a house renovation project. Basically, I put the cables the wrong way around so that the ends that go in to the DVR are with the camera and the ends that are meant to be connected to the camera are with the DVR.
- Yellow is video White is audio You can swap those if you want because they are just wires. The colors are so that we humans can hook them up. I am assuming that the red can't be plugged into the wrong port.
- 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.
- you could connect computers via direct cable get right of entry to on parallel port. you additionally can use a bypass cable for this u could desire to remeber a rule for create a bypass cable it incredibly is 1326 ability connect a million cable with third of different and a pair of with 6 th cable of different. have relaxing
- Q: Hey! I bought a new sound system for my truck including 4 new speakers, a sub, a 5-channel amp, and I'm running all new wiring. So far I've got the 3 RCA cables ran, along with the blue remote turn-on wire along the right side of my truck. I plan to run the Power wire down the left side and then to my amp.I've heard that you put the power wire and RCA cables on different sides, which is what I've done, but is it ok for my speaker wires to be run beside or close to the power wire(4-gauge fyi)?For example, the right side speaker wires wont be near it, but the left side speaker wires will be...Will this cause any weird noise from my speakers?I don't have the names/etc of all my gear right in front of me, but if u rly need it, I will quot;add detailsfor you! Thanks!!
- Separating the power the speaker wires is not as important in a car that uses DC voltage as it is in a home system that has AC voltage. It certainly doesn't hurt anything, tho.... If you do run them across each other, keep the intersection as close to a good right angle as possible. And, air is a very good insulator, so keeping some distance between the power the speaker wires is also very good.
- 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: Hey y'all , so I got this LG X120 Netbook thing and although it works fine when power supply cable is connected, it won't play just by getting supply from its own battery..also i tried starting it up with the power cable on, and after a few moments I unplugged it, and the screen went black-I mean the netbook was turned off by itself..any help with that? thanks
- It sounds like the problem is one of three things. Either the power cable is the wrong voltage/amperage (these should be labeled on both the charger and the bottom of the laptop and/or battery) If the charger specs don't match the battery specs, it can cause this to happen. Maybe there was a mess-up that caused your to receive the wrong charger. The second possibility is that the battery is bad. A third possibility may be the connection from the battery to the laptop. It may not be making a good connection or could have some internal circuit problems. In any case, if the laptop is still under warranty... I would try returning it. Even if the problem can be fixed from the above suggestions, a problem like this early on tends to be bad news of what lies ahead.
- Q: I'm lost i cant find a hole in my ford c-max firewall to install my power cable for amp can someone help me as i am traveling this sat to France by car .
- In most vehicles there are spare holes filled with rubber plugs. Pop one out with a screwdriver and make a hole in plug a little smaller than the size of the wire for a very tight fit. If it's a smaller size power wire, it can sometimes be run through the same grommet as the vehicles main harness. Be very careful not hurt the existing wire. I have seen people get careless and screw the harness up and it's not easy or cheap to fix. When doing this I usually use a stiff wire (a small diameter yet long screwdriver can work too) and slide it through the grommet. I then use electrical tape to secure the power wire to stiff wire and pull it through. Make sure your penetration point is still leak proof after doing this. You may need to use some silicone and or electrical tape to seal it up.
- Q: I have an IVI Checkmate receipt printer, but do not have a power cable for it. Where can I get a power cable for this receipt printer?
- Hi.. I think for all your power cable and cable accessories requirement this site can be helpful
- Q: I have a MSI K7 Motherboard... it has a SATA power cable but no data cable. Which kind of confuses me. Please help. Thanks =)
- A word of advice ... if you plan to install Windows on this new drive you will need to prepare a driver disk for the SATA adapter. During the first stages of Windows install it will ask you to press F6 to install any third party drivers for RAID or SCSI .... without it Windows may not detect the adapter hence the SATA drive. regards, Philip T
- Q: I was looking at buying the MSI HD6850 cyclone OC/power edition but on the msi website it says it includes an external power cable. Am I missing something? Do I need more than the standard pci-e 6 pin connector from the PSU?
- Some graphics cards require you to connect a power cable to the board. As it requires more power than it can get through the pci connection.
