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: A pair of Copper wire mains, each of 3.87 sq.cm cross section use to transmit the power, a distance of 915m for 10 hours a day, 80 kilo watt at 200 volts are taken from the mains, find power lost in cable per day at resistivity 1.7 micro ohm.cm.Note: Question is talking about A PAIR OF COPPER WIRE
- Power loss per day is meaningless, I assume you mean energy loss per day, or power loss You have to calculate the resistance in the wire. Resistance of a wire in Ω R = ρL/A ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m? A = πr?, r is radius of wire in m resistivity Cu 17.2e-9 Ω-m 3.87 cm? = 3.87 e-6 m? R = (2*915)(17.2e-9) / (3.87 e-6) = 8.13 ohms 80 kW at 200 volts is a current of 80000/200 = 400 amps You cannot put 400 amps through an 8 ohm resistance, as that requires a voltage of 3200 volts, which we don't have. So the premise of 80 kW is not possible. Perhaps you copied one of the numbers incorrectly. .
- Q: Power Cable Check Well b-type covers show what?
- B-grade steel fiber concrete check covers are used for motor vehicle driving, parked urban roads, highways and parking lots C-grade steel fiber concrete check covers for slow lanes, residential quarters and sidewalks D-grade steel fiber concrete inspection covers for green belts and motor vehicles can not travel, parked lanes and venues
- Q: Hi! I want to buy I new Hard Drive but I've got a problem. I have the IDE conector but I don't have the Power Cable. It is connected to my Video Card. Can I add a new one? Can I use a power cable from a optical drive(CD/DVD)? Thanks!
- All you need to do is pop down to your local computer store and get a power splitter, just make sure you get the right type, IDE and SATA drives have a different kind of power connector, so just make 100% sure before you buy!
- Q: Can I do the big 3 upgrade by only doing the 2 ground cables(battery to chassis and engine block to chassis) now and doing the power to the alternator at another time? Will this give me a little performance boost until I can get enough material?

- Q: I don't have the power cable no more..its an 8 pin power cable and it has on the back120v24v12v5vits a round adaptor and it looks like an old computer keyboard but it has 8 pins.thanksromeo
- Sounds like you need a standard S-Video Cable, available just about anywhere. We can get them locally at the 99cent only store, walmart, target, ect
- Q: You have not connected the power cable to your video card. Please refer to the 'C settings started guide' for proper hardware installation.

- 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: best buy geeks advised me to buy wd320sata h/d to replace seagate barracuda 7200 h/d....... cannot connect .... no sata connector on motherboard that i can find....... instructions says need power cord. any suggestions????????? please and thank you.........
- The SATA specification demands 7 pins to flow archives. Conveying potential to gadgets demands heavily greater desirable potential throughput than conveying archives. potential adapters have been redesigned for SATA gadgets from usual Molex to make it as common to plug and unplug because of the fact the recent SATA archives cables. The redecorate made the pins smaller. With electrical energy bypass with the aid of potential conduits, travelling electrons inevitably hit the molecules of the conduit itself, which excites the molecules and the molecules launch this further potential as warmth. once you're attempting to maintain an identical bypass of electrons over the years yet shrink the actual length of the conduit (as develop into finished with the SATA potential spec), an identical variety of electrons could desire to bypass interior the path of the conduit over the years yet with the aid of a smaller pipe. This focused 'site visitors' leads to greater collisions, ensuing in greater desirable warmth output from the steel conduit. with the intention to have the smaller pipe and an identical quantity of site visitors without overheating the steel conduit to the factor the place it burns the plastic housing, you may desire to have greater of the smaller pipes turning in that site visitors. think of of it like highway site visitors. in case you may desire to make a highway smaller, the site visitors that already traverses that highway will now could desire to deal with one yet another for that narrower thoroughfare. with the intention to maintain site visitors shifting and forestall site visitors jams, you may desire to construct further roads to accommodate that exact same site visitors quantity. only area of this analogy that would not correlate is that electrons do no longer decelerate once you're piping them with the aid of a smaller conduit.
- Q: i bought a car from some guy.he had 2 amps but he took out onehe had the power cable running from one amp to the other. i just recently bought another amp and i was wondering if its safe to do this.he said it was working fine.he was powering 2 10 subwoofers.thats what im planning to do
- its safe but its better to run 2 separate wires due to you are wanting to use more power and one wire has a max load that it can handleyou run 2 and you will have more power to each amp
- Q: I'm not sure which cables I lost exactly but during a recent move all the cables for my Xbox 360 were lost. I was wondering what the cables are called like Ethernet cable or power cord etc. and where I could buy them from just the cables, such as at best buy.
- Here okorder / You don't need to pay $50 for good HDMI or $20 for Ethernet cables - good quality can be had for considerably less. If you need further guidance write back with Additional Details, OK? Good luck!
