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: how do i install the power cord on the 8600 gts. Is just attaching one of the two receivers on the cord to the graphics card and the other end plug in one to a power thing the right way.
- Some specialized power supplies have the power cable built-in and you can plug that directly into the card. If you don't have one of these, then the card probably came with a cable that requires you to plug in two 4-pin power cables (same type that plugs into your CD drive off your power supply) and then the other 6-pin end snaps into your video card.
- Q: What are the causes of the power cable fire accident? How to prevent
- with a white cable to facilitate the distinction between the cable
- Q: i herd that 2 cables in a network (ethernet) cable just carry power. and was wondering which 2 colours or on what side the 2 are.also how much voltage they carry.was hoping to make an easy router mod to stop with the head issues.cheers.
- u mean wires by cables ?!
- Q: I know Ethernet cable is much more susceptible to electromagnetic interference than fiber optic cable, but is fiber completely immune to it? I want to wrap a fiber optic cable around a 230 volt power line going through my attic for about 150 feet. Will this cause problems?
- Hi There, The 220 volt AV power cable will not cause any interference but it is not a good idea. The fiberoptic cable should be ran separate. It is a little more work but the right way to route the cable. You have to be very careful not to exceed the bend radius and wrapping around an existinf power wire might cause a problem. =====this is from the link below======= Do not install a fiber optic cable in a conduit or duct that already contains cabling, regardless of the cable type. Existing or new empty ductwork can be modified to accept several different installations by the placement of innerduct within it. ======================================... Hope this helps, Al
- Q: The power button doesn't appear to be wired correctly. I press it and nothing ever happens. The only way to shut it down is to forcefully remove the power cable. My PC also does not shut down when I select shut down in the start menu. It just restarts.

- Q: Single single 10kV power cable with copper shield can wear steel pipe? What will be the impact?
- Do not have to be so troublesome, such a phenomenon even encountered, is the basement of the air defense, similar to the landlord said the phenomenon can be taken as follows: . first with linen live wire and casing blank. . filled with asbestos cement and compaction, the surface concave sleeve 3-4 cm. . with plugging the king (5 yuan / bag) add water and mix well, smear the surface to smooth. . the work is completed, do not hurt the core and the practice proved no leakage within two years.
- Q: I bought a grand am and i was going to install a amp. in the trunk there are servil wires comming out of the side but idk which is with what does the power cable look like? the rc cables remote ect? all the ends are just cut off
- You will need a amp kit. Most Kragens auto parts stores have them or walmart. There are a lot of different colors to amp kits so there is no way to tell you for sure. When you have your new amp kit it will make a lot more sense. Hope this helps
- Q: what is the resistance of overhead power cables?
- Search for resistances per mile aerial use' and you will find some info from Power systems stability handbook By Anthony J. Pansini
- Q: My car wont start and only starts after moving power cables up and down. Im not sure what the problem is. If i slightly move it I see alittle sparking under the engine. When i manipulate the battery power cables it manipulates all the wires connecting to it so i cant pin point where the problem is. When i try to start ignition there is zero sound. When i manipulate cables it starts right up and cranks fine.
- Sounds to me that you have a BAD BATTERY here. Is it the ORIGINAL factory one, or some after market one?? When the cells inside a battery short out internally, sometimes if you jiggle the cable, it will make a false, temporary connection inside. Remove your battery, and have it bench tested. Get another factory battery, or an OPTIMA battery or a DEKA battery. THese all tested higher than usual. A good EUROPEAN battery is another good choice, if you can find one in that exact size. GOOD LUCK!! CLean your IAC valve and throttle body. THis will insure the wuickest ,easiest starts. GOOD LUCK!!
- Q: I am installing a sound system in my car straight from scratch. I have built the subwoofer enclosure but now I have run into a problem. The existing amplifier power cable is too short to reach my amp. I was wondering if any other cable could be used as a substitute to extend it just a few more inches or do I need to buy a whole new amp kit? Thanks
- saftey wise buy a new wire if you go best buy curcuit city you can buy the red power cable by the foot
