Electric power communication network is major communication network of the country and support networks of modern
network with the main feature "three second high". Power industry has a unique advantage in developing optical fiber
communication as power network spread all over the urban and rural areas and laying fiber optical cable along the
electric power lines has high reliability and economy. Special cables used in power communication network mainly
include ADSS cable and OPGW cable. OPGW cable is special for power line formed from traditional structure added
fiber unit. It also has the function of overhead ground wire and optical cable.
This optical cable uses 6 loose tubes (or partial gasket for packing) to wind around the FRP and become the a complete
round cable core, which is stranded of certain number of Kevlar with potentiation after being covered with PE internal sheath.
Finally, the PE external sheath will be squeezed. The loose tube is made of the materials with great temperature properties.
Several single mode or multi mode optical fiber (2-8 core) of a proper extra length and the oil jelly used for moistureproof optical fiber are put into the tube. The slits of the
cable core are fulfilled with water-blocking compound.
| The compact and round shape cable core is a combination of the loose sleeve pipe (gasket for packing) and center-strengthened core, the gap in the cable core is filled with water retarding compound. The polyethylene overlayer will become optical cable after the plastic-plated Aluminum belt is covered vertically. |

- Q: Power cable ZRYJV-4x70 + 1x35 What does it mean? Can you explain it?
- 2 cable in a variety of environments in the laying of the layout, spacing should meet the design requirements
- Q: What I really just want to know is the equation and basic concept on how to determine the optimal length of power cable needed to connect two poles while knowing only the linear density of the cable.It does not matter how much sag is produced because of limitations due to the strength of the power cable.
- you could connect computers via direct cable get right of entry to on parallel port. you additionally can use a bypass cable for this u could desire to remeber a rule for create a bypass cable it incredibly is 1326 ability connect a million cable with third of different and a pair of with 6 th cable of different. have relaxing
- Q: why my pc is shutting down and restarting only when removing the power cable and connecting it again?
- It's shutting down because you're removing the power cable. I wouldn't really do that when your computer is on... It's not good for the motherboard or anything, for that matter. It restarts again basically because it's still being told it's on, so it reboots when it's plugged back in.
- Q: I bought a Garmin GPS, but my cigarette lighter is near my gear shift. Does anyone know how to add a power cable so the cable is behind the gps on the window?. I can always take it somewhere for about $100.
- As you say, take it so it is professionally done. Working on cars is very complex and requires an expert. Always best to seek a professional. Also always it is require to capitalize the acronyms of titles. Please capitalize GPS 100% of the time.
- Q: i'm using an older mac at uni to do illustration, i pulled the computer round to put a tablet in it and the computer shut down, there are about 20 computers in the lab....the power cable at the back that is connected to the monitor is loose, i tried to put it back in but it's crackling....can i get electrocuted from putting it back in? i can't shut down all the computers so there's still electricity running through...thanks
- let's hope it's not shorting out, follow the path of the cord to where it terminate it should plug into a strip outlet on the floor or against the wall once found uplug it ,plug the power cable into the monitor then plug in the other end with the monitor off
- Q: How can we make out the physical size of a power cable if the cable is said to be 4 core, 150 sq.mm ??? How will we measure the diameter of this cable ???? please suggest......
- A 4core (electrical) cable of that strength is usually built up from quarter circle shaped sectional wires. (Think of a pizza cut into four even pieces.) So, calculate the outside diameter from this point and add 4 times the insulator thickness. Example: 400V 4core cable has very likely 1mm insulator thickness. 150mm? * 4 cores is 600mm? total. By A=PI*d'*d'/4, d' being the diameter without insulator, would be d'=2*sqrt(A/PI)=600mm?/3.1415...=2*sqrt(...? Now, as said above, add the 4 insulator layers, and then you would be at approx. 31.7mm outside diameter.
- Q: what kind of power supply cable plugs into the hard drive?
- they are called molex connectors, for optical and hard drives, berg connector for floppy drive
- Q: I have one Ethernet cable running to a WiFi antenna. The antenna is powered by the Ethernet cable, using PoE. I want to be able to plug the current cable into a hub or switch, so I can connect other devices (non PoE) like an Xbox 360 or PC, but I also need to maintain the PoE to the antenna. Taking the antenna off PoE is not an option. What kind of device can I use to split this PoE line into PoE and non PoE cables?
- familiar ethernet cable is nice for 100m (approximately 328 ft), Any device which includes a hub, router etc. oftentimes acts as a repeater, 'cleansing' and boosting the sign to make greater desirable the variety. The distances you point out will have not any impact on ethernet. besides the shown fact that any undesirable connection or cable alongside the way can doubtlessly injury the sign. I have not any issues extending broadband ethernet hyperlinks over a number of thousands of metres with strategically placed small switches alongside the way for serious enterprise use.
- Q: I have recently purchased a SAPPHIRE 100228L Radeon HD 3850 512MB 256-bit GDDR3 AGP 4X/8X HDCP Ready Video Card.
- should have come with a power cable. sometimes these are hidden in a compartment inside the box. take all the inner cardboard out. It would be pretty unusual for one of these cards to ship without the cable.
- Q: Is a graphics card power cable needed because not all graphics cards come with one? And if it isn't needed, what is the benefit?
- The more powerful graphics cards require the 6-pin power connector to a PCI-E slot. The benefits of NOT requiring one are: 1) The card uses less power, which might save the expense of having to upgrade the power supply. 2) The card works with power supplies that don't have the PCI-E cable, without having to buy an adapter. The best card which doesn't need a power cable is the ATI Radeon 4670. The card models above that (like the GeForce 9800GT, Radeon 4830 etc) all require the cable.
