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: Power cable 5-color line, respectively, what color, what role?
- YJ: XLPE insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated voltage: 8.7 / 15 kV (phase voltage 8.7 = 15 / 1.. line voltage 15kV) 3 * 300: Three conductor cross-section of 300 square copper conductor Another: If YJLV is the aluminum core. Here is not marked what the material is conductor, you can default to copper conductor.
- Q: i bought a 650w power supply for my pc because i bought a graphic card that needs 550w. So my question is will my regular power cable which came with my computer work on the new 650w power box.P.S- my computer is a 300w
- Yes. it is the same cable that comes with every computer, printer, monitor. OK it's the same cable that comes with 95% of them
- Q: I want to tidy up all of the cables behind my desk. I have some of that special plastic wrap to do it, but I'm worried about overheating and induction.How many mains voltage power cables can I safely have in a single bundle? What about speaker cables and TV/monitor cablesHow can I tell if I have bundled up too many cables together, are there any warning signs?
- I neatly zip tie each cord separately. Use only what's available on each power strip. Don't use a bunch of extension cords.
- Q: Question says it all.
- You wont see any problem as far as the cable is concerned, as each device deteremines it's own resistance, and which will result in a specific amperage being drawn from the system (constant voltage), so no need to worry about that. The one issue you will want to address is making sure you reduce your fuse amperage. You want your fuses to be rated just over what you system should normally draw. Any more and your system might be damaged if it ever experiences a short, as your fuse might not respond as quickly as one with the correct rating. (There are several other reasons to use the correct fuse, but you get the idea, it's just safer and smarter) I'm assuming you are refering to 1200w Max power when referring to cable, which would probably be something like an 8Guage, hich probably has a 40Amp fuse, which is a pretty solid choice for a system under 500w (assuming you are referring again to max, not rms). You might want to swap it out for a 30 amp, thought, just to be on the safe side. If you are reffering to 1200w rms, then you have a 1 guage or so cable, and you probably have anywhere from 80-150 amp fuse using either Maxi or ANL fuses. If this is the case, that's fine, just make sure you switch out those fuses for the lowest ones you can get. I beleive ANL start at 100amps, but I think you can get maxi's as low as 60 amps. (Anything you need can be gotten at BestBuy, Circuit, or any local audio shops)
- Q: I bought a new amp and sub to replace my old ones. I disconnected the battery, unplugged the old amp and plugged the new one in and when I reconnected my battery the power cable began to smoke at all the exposed ends and got very hot. What causes this? Is it because the new amp requires more current than the old one and that is causing it to get very hot? And what is the solution to my problem?Thanks
- you are creating a short circuit with the battery if this is happening while the amp is not on. disconnect all wires and make sure your positive lead goes to only positive terminal /amp input. then do the same for the ground. if you dont have a fuse protecting the wire it will get so hot it will melt the insulation and start a fire. if this is happening only when the amp is on and your system is pulling a large current through it (music real loud) then you need to upgrade your wires asap. make sure you have a fuse protecting the power wire close to the battery and a fuse whenever you downgrade in size of wire. a $1 fuse with the correct rating for the wire its protecting will safe your *** if you short circuit.
- Q: if found the reistance then what are the acceptable limits such that replace the cable or repair the cable
- See the document by Megger on how to determine if a cable is good and much more. This is a very good document that covers both static (insulation hipot testing) and TDR fault location methods.
- Q: I have a ZXi8008 and there's a cable that goes out to the head unit to turn on the amplifier, which is different than the power cable. But in this car, i have not installed a new head unit. Where do I hook up this cable otherwise? It needs a constant power supply to be on.
- i would hook it up to the power cable from ur stero that whay the amp will only come on when the radio comes on. that way u wont drain ur battery, thats if ur talking about the remote cable
- Q: where can i put my amp power cable through my bulk head in my 1999 1.8L 16 valve ford mondeo lx?
- Find the main harness going through the fire wall and follow it
- Q: why use of black color for electrical Power cables ?
- Because okorder /
