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: When I plug and unplug a power cable to the net in my home for let's say, 50.000 times a day, why doesn't my electricity-meter not count that power for the monthly electricity fee?When I unplug the cable the cable should still have some electricity flowing through it at the moment of unplugging. That electricity disappears very shortly after . But after unplugging it, it doesn't have any electricity anymore. So some electricity is lost right? How does this work?
- Basically, the appliance works on the current flowing into it. When you unplug the cable (or hit the OFF switch, same thing) the current stops flowing, then the appliance then stops working. Very simple. .
- Q: Hey, my parents just bought me a turntable and I have no idea where one of the cables would go into a normal stereo or what I might need to buy to be able to plug it to a normal modern stereo.
- That cable is neither a ground nor does it hook to the turntable. If it hooked to the turntable then you would be hooking it back into itself. That connector is probably a cable used for connecting to a stereo system that the turntable came with. Looks like a low voltage cable so the turntable was most likely getting it's power from the stereo. My guess is that you are probably out of luck.
- Q: is it possible to split the live wire feeding my car stereo into 3 feeds so one is my stereo , two is my satnav power cable and the 3rd is my reversing sensor display. will this overload the wires? any advice how i can do this would be most helpful. thanks
- I'm assuming you mean the wire providing the 12-volt power to your radio? And you want to connect other unit's it? It all depends on how much current is drawn by the additional units. Do they have fuses? What sizes are they? Backup cameras usually draw very little current and have really thin wires. Shouldn't be a problem. What type of navigation device? Does it use a DVD-ROM or is it just on a chip, like a portable Tom Tom, Garvin, etc.? If neither of the units' fuses exceed 5 amps, I'd say you're safe (in most cars) running it from the radio's power wire. However, you didn't state the type of car. Late-model GM cars or Audi/Volkswagen have low-current radio wires that use computers. They are known as data bus or can bus systems. I'd avoid connecting to these.
- Q: is it possible to run a 2-wire AC power cable (2x2.5mm2 or thicker) from the telephone junction box to the inside of the house instead of using an ordinary thin phone cable? will that affect the voice quality or maybe an ADSL setup? the distance is approximately 50 meters.thanks a lot.
- telephone wire is twisted pair.. which reduces interference, and induction problems... using electrical cable in place of phone cable would work but not without acting like an antenna and picking up all kinds of back ground interference... as well as potentially degrading the signal for your DSL...
- Q: hi i need to connect a extra cd rom drive to my computer and dont have enough 4 pin power cables in my computer how would i get those and how would i install those. Thanks
- These are called Y-Cable. Buy one. Remove the power cable from the old cdrom. Attach it to the newly purchased cable. Now you get 2 new points. Attach one to old cdrom and other to the new cdrom.
- Q: is not giving direct contact to my lights....so i just want to replace the power and ground cables for the headlights.??? please help
- The power for the headlights comes from the front fuse/relay box, usually on the drivers side wheel well under the hood. There should be a relay in the box for the headlights.
- Q: My power supply (tagan 1100w) has an 8pin m/b power cable but the PCIe one looks cooler.
- Noooooooooooooooooooo!
- Q: Does throwing punches with weighted cables increase punching power?
- No power is genetics. You either have it or dont. It'll increase speed. Don't do to heavy or you'll damage your ligaments and tendons long term.
- Q: I want to know if the dell vostro 260 has it
- Power supply . yes it has one PCI-E slot , no it does not nave one PCI_E cable - no not that either I am guessing you want to know if you can install a graphics card for gaming? the answer is NO
- Q: I'd like to know what type of wire/specs. for a 3 phase high power cable that can handle a 41.6KVa that will be buried under the ground? The voltage will be a 220 volts in 60 Hz. could you show me how to calculate or any charts are really appreciated.
- There's not enough information in your question to give an exact answer. Figure the highest current in any of the phases assuming that your load may not be perfectly balanced or it may have a nonlinear current waveform. That will establish the minimum size of the conductors. Another factor to consider is the maximum allowable voltage loss at full current. You also need to know if voltage sags due to startup or inrush currents will be a problem. A long cable will need to have larger conductors to keep the losses within your acceptable range. Don
