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 | |||

- Q:I only see the power supply (with a cable to connect to the laptop), but I don't see the AC cable. In the specs it only says quot;Cables Included: 1x Power cable - 3 ft.quot;I want to know if it includes the whole charger, or just the power supply to connect to laptop.
- The cable from psu to laptop is not removable so the 1x power cable included is the removable AC cable.
- Q:I recently moved from one state to another and brought my XBox 360 and games with me, but forgot the power supply, power cable and AV cables. I can't get a family member to ship them because they are all locked in storage and even if I mailed the keys, they are probably buried under everything else anyway.Most electronics stores sell the AV cables so that isn't a problem. But nobody seems to carry the power supply. Most places I've found online carry generic or no-name brand equipment which I want to stay away from for something this valuable and will only purchase genuine Microsoft equipment. Where can I look or buy it? Will I have to order right from Microsoft themselves?

- 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.
- Two conductors are two conductors, unless there are high-frequency issues. In this case it appears that if you are replacing parallel (not twisted) wires with another set of at least equal thickness, you should be okay. Since ADSL is used on parallel wires, without twisting them, the frequencies conducted should not present problems.
- Q:What is resistance of the cable (resistivity of copper is1.7x10^-8)Answer is 14 ohms. But please explain how do we get there in full detail.
- Resistance (R) of a wire is given by: R = ρ.L / A where (ρ) is the resistivity of the wire in Ω.m ; (A) is the cross sectional area of the cable in m? ; (L) is the length of the wire in metres. Radius (r) of one strand = (0.51 / 2) = 0.255 mm = 0.000255 m Cross sectional area of one strand = πr? = (π * 0.000255?) = 2.0428 x 10^-7 m? Total cross section of cable = (12 * 2.0428 x 10^-7 m?) = 2.45 x 10^-6 m? R = (1.7 x 10^-8 * 2000 / 2.45 x 10^-6) = 13.87 = 14 Ω to 2 significant figures.
- Q:I recently bought a Mackie CFX20 MKII and it came with a European 2 pin power cable but I need a UK 3 pin power cable.On the plug end of the cable it says (16A 250V~) but on the connector end of the same cable it says (10A 250V~) I have no idea what cable I need to buy for this so an answer to what I need or a link to what I need would be great.Thanks.
- Be care full because a lot of european countries only have 240 volts. If you intend to use 110 make sure the mixer is switchable. If it is there will be a switch for the two different voltages. Some are made to work either way but the switch need to be in the proper position to avoid damage from either to much or not enough voltage. I work for a sound company and sometimes we get sent stuff wired for over seas. Some times it has to be exchanged because it isn't switchable. You need to contact Mackie and make sure you get the right cable. I'm sure they have a toll free number and web support. You may need to exchange the mixer.
- Q:My amp was working this morning. On my way home, the power cable came out somehow. I put it back in and it wasn't powering on. The amp fuses were blown, I replaced them. Then I went to hook the battery terminal back and the fuse in my power cable blew instantly. I replaced it and tried again and it blew again. Also the fuses in the amp are fine now. I did the same process when I installed my amp the first time and it was fine so I don't know why it's doing this now. The amp is a Boston Acoustics 800w RMS amp and an 80a fuse. Any ideas?
- Look at your previous question. I told you what it probably is. Either you have strand(s) of power wire stick out somewhere and touching something it shouldn't be touching. Or. You tapped the power wire on something during removal and cooked the amps power supply. The current flow from a shorted circuit gets very hot, very fast.
- Q:which cables cant be near each other??(will cause noise radiation if put together)i gotta run some wires through my car and i dont know wich ones to keep away from others. im runnin...4 gauge (eventually will be 2 gauge) power wire for amp2 speaker wires for rear deck speakersrca cables for ampremote turn on wire for amp
- yes. run your power cable on the othr side of your car from the rcas. your remote and speaker wire shouldn't affect it
- Q:hello guys,how does a power boost cable works?what is the difference between a usb cable and power boost cable.
- It is simply a 2nd USB for power alone, it does not use both USBs to transfer files, just one, the 2nd is just for additional power to improve the performance of the hard disk
- Q:Hi. I was snaking 40 feet of underground burial power cable thru a PVC conduit. As I did not have any cable pulling lubricant, I used JOY dishwashing liquid detergent as a lube for pulling the cable with a snake. Will that damage or detiorate the outer jacket of the cable it is still in the conduit. The flexible conduit I used is water tight and I have plugged both openings with silicine caulk.
- It'll be ok for about 5 years. The chemicals will eat through the outer casing which is more resilient than the inner insulation. Next time, go to Lowe's, Home Depot and purchase some Wire-pulling lubricant.
- Q:lets say for an optical drive, the power cable has four pins. im guessing that there is power (12v?) and ground but what about the other two?im trying to plug a pair or old neon sticks into my car for accent lighting and i need to know where to put these wires at, if they are all neccessary.
- The four pin connector that is used to power PC drives supplies two different voltages: +12 volts for the motor +5 volts for the electonics The other two pins are ground pins. ________ / .............. |..1..2..3..4..| |.................| Pin Function 1 +5 V 2 Ground 3 Ground 4 +12 V
