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 |
2 | PVC insulated PVC sheathed flame-retardant branch cable | FZ-ZRVV | FZ-ZRVV-3 | FZ-ZRVV-4 | FZ-ZRVV-5 |
3 | PVC insulated PVC sheathed fire-resistant branch cable | FZ-NHVV | FZ-NHVV-3 | FZ-NHVV-4 | FZ-NHVV-5 |
4 | Cross-linked polyethylene insulated PVC sheathed branch cables | FZ-YJV | FZ-YJV-3 | FZ-YJV-4 | FZ-YJV-5 |
5 | Cross-linked polyethylene insulated PVC sheathed flame-retardant branch cables | FZ-ZRYJV | FZ-ZRYJV-3 | FZ-ZRYJV-4 | FZ-ZRYJV-5 |
6 | Cross-linked polyethylene insulated PVC sheathed fire-resistant branch cable | FZ-NHYJV | FZ-NHYJV-3 | FZ-NHYJV-4 | FZ-NHYJV-5 |
- Q: my father took away my cable so i can play the game but i just want to take the game out of it
- You can risk breaking your xbox or you could also pick any random house on your street and knock at the door and ask to plug your xbox with their cable to remove the disc. Every household owns an xbox Or just stop by a friends house with your xbox
- Q: i have a ASUS M4A87TD-USB3 mobo and a Corsair 550 Watts Power Supply. Ive looked in the manual andit says you need to connect the one that ive connected and a 4 pin. It says that if you dont connect the 4 pin the computer wont boot! is there a way around this or it f**ked?
- Before purchasing a power supply you should always first check to see if it is compatible with your motherboard in the following two aspects: 1) Does it provide enough power for the motherboard 2) Does it have the appropriate connectors for my motherboard. There are also issues with certain high performance processors requiring very clean or high regulated power supplies (i.e. very little ripple, etc). As long as the power supply offers the voltages you need on one of the connecters, there is probably some sort of adaptor you can purchase... or you could hack something together. But, again, the power supply may have intentionally left off the connector you need because it does not fulfill the strict electrical specifications required by your motherboard. In other words, if you don't know what you are doing, it is probably best to just purchase the correct power supply for your hardware. Forcefully adapting an inappropriate power supply into your machine may later result in unstable system performance.
- Q: I've lost the power cable (and other regular connection cables) for my Dell computer but have some from another computer (but don't know the make of them). This might be a stupid question but..can I use these for my Dell computer or do they need to be Dell cables?
- Go ahead and use it, no problem. For the sake of convenience, all PC power cables consists of three wires. .. one for Positive (Phase line), one for negative (Neutral line) and last for Earth. OK, you can also easily make up one if you have the plug connectors.
- Q: What does the cable (YJV-5 * 6) mean?
- ZR-flame retardant Y-polyethylene J-crosslinked V-PVC sheathed YJV is copper core, YJLV is expressed as aluminum core, where L is aluminum. 22 indicates the type of armor armor, and 32. So the full name is: flame retardant copper conductor cross-linked polyethylene insulated PVC sheathed power cable 4 * 16 that there are a total of four copper wire, which each cross-sectional area of 16 square millimeters
- Q: Its on power and one is in a pc monitor and one is lying on the ground. Will the electricity go through the cable that is not connected and lying on the ground? is this safe to touch with hands or shoes?
- Pasting the reply I gave to the other (deleted) question: Assuming these are the IEC-standard power cables I'm thinking of, yes and no respectively. Electricity will be able to reach both ends, but the plastic insulation at the end of these connectors should disallow any contact between you and the live pins. You may want to consider covering it up in non-conductive electrical tape, though, just to be sure no debris get in causing it to go live outside of the connector.
- Q: How can we make out the physical size of a power cable if the cable is said to be 4 core, 150 sq.mm ??? How will we measure the diameter of this cable ???? please suggest......
- If the size of the cable is 4 core, 150 sq.mm; = the cross sectional area of each core is 150 sq.mm. The diameter of each core is gotten from the formula C = ╥d. From this $ substituting values for ╥ and C; We find that d = 150 / 3.142. = d = 47.74mm :. for 4 cores, diameter of cable = 47.74 * 4 = 190.96mm However, note that this is only mathematical. On the field, the dimension of a cable is usually specified based on the number of cores it has, and the cross sectional area of one of the cores as the cores are all of the same size.
- Q: my amplifier s power cable is not long enough to reach battery . so is there any problem if i take another piece of power cable and then attach them ?
- It's safe enough, as long as you make a good splice, and insulate it well. For automotive use, I like insulated, crimp-on splices. If this is a really high-power setup, and the power cable run is that long, you may be better off replacing it with heavier-gauge wire.
- Q: will leaving the power cable in for my laptop hurt the battery?
- No, I've always done that with no issues.
- Q: Copper core power cable models which several kinds
- First, the total number of wire and cable products are thousands, applied in all walks of life
- Q: Cable YJV-1KV-5 * 10 pipe laying, including cable head system with what fixed amount?
- KVV is the control cable, generally do industrial control; and RVS is twisted pair, generally used for weak system, to eliminate the interference requirements of the occasion, such as two-wire bus system, specifically, the electrical fire bus more Such as RS485 bus and so on.
