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 | ||

- 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.
- Not, it is not.
- Q: I am not sure of the reason but when i plugged in the power cable there was a crackling sound only for a second and then it stopped. I remember a similar occurennce when i had a loose electrical circuit would this have done any harm to the computer.
- you merely experienced the stunning scent of silicon frying. possibly the processor overheated and burned. consistent with threat a skill surge brought about your powersupply to prepare dinner the motherboard. In any condition, that computing gadget has been cooked. i admire that scent. electric warmth on silicone and distinctive mineral circuits.
- Q: My computer speakers have a control tower(volume etc.) that plugs into the back of the subwoofer. I would like to move the tower further away from the sub then the cable allows. Is there an extension cable I could get?On the cable it says:2464 E205890 AWM 80C 300V VW-1SCThe end of the cable is round and has a row of two pins, then a row of 4 pins and then a row of 3 pins.
- For Extend Power Cable!?. Find correct extention any store tools category Or find in internet Searching. Good Luck. Comentary: Take precaution about Where install and take all the precaution. I remember to find one in Lowes
- Q: Im running a dedicated power cable from battery to trunk for 2 amps and i just want to know if drilling a hole through the firewall is the only way to do it? What happens in 15 years when the hole gets rusted and coroded from the moisture even with a gromet?
- 2 amps is a pretty small current so it doesn't need a big cable - there are other cables passing through for the back lights, find out where they run and see if you can just ease another one through the gap,it might work with a little lubrication. Just don't try to poke anything sharp through the hole. There are special fish wires that electricians use to get cables through holes conduits, you could try one of those or at least see how they are shaped so you can use something similar - you'll only need a short fishwire you probably have to buy a 5m length if you want the real thing. Good luck.
- Q: will leaving the power cable in for my laptop hurt the battery?
- Newer batteries cannot be overcharged but it is not advisable to leave the power cable plugged in when the battery is at a full charge. It will not hurt the battery but overtime your battery will not sustain a charge for as long as it should. My best advice would be to fully charge and let your battery drain to near completion and then recharge. Give your battery the exercise it was meant to have.
- Q: power cables for 3 phase wire
- Three wire, single phase, 120V uses: line (usually black), neutral (always white), and ground (green or green with yellow stripe). Three wire extension cords should be sized for the estimated load in Watts, and the length of the cord. Armored cable for interior wiring must be #AWG14 minimum. Add details for a better answer.
- Q: I don't want to run it under the car, but I can't find a place to run it through the firewall... Do I need to drill a hole?
- Look under the storage compartment on the passengers side. look under the dashboard on the drivers side, locate holes then look on the inside of the cars side skirts you should be able to remove the skirting and lay cable under there.
- Q: my portable HD has 2 USB cables, one for the computer and one for power... why?
- many devices get power from usb. however the new hard disks, required higher current/power to run and it cannot be provided through single usb cable. hence you have to use two cables.
- Q: Due to the large spans the signal must travel it must be amplified or reconstructed at one point, taking into consideration that everything happens underwater, where does the box that reconstructs the signal get it's power.
- we can harness the power of currents and tides to do so.(very large bouy type generators)
- Q: Most systems are about 1 thousand watts, the red power cable is really thick but then the speaker wire is really thin about 12 gauge, shouldn't the speaker wire be as thick as the power cable?
- No. Wire thickness is about current (and length). And current is inversely related to voltage. When voltage is high (like an amp's speaker outputs) it takes less current to make power. When voltage is low (like a car's alternator/battery) it takes a lot of current to make power. Alternator voltage is ~14v. Amplifier output voltage is commonly 20-40v. Your 1000w example... Say it's a fairly efficient class D mono, 1000w at 2 ohms and 80% efficient. To produce that 1000w requires 1250w from the alternator at around 13v. Ohm's law says current (I) = power(p)/voltage(e) So I = 1250/13, I = 96A On the output side -- I = sqrt(p/r), I = sqrt(1000/2), I = 22A
