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: Did not find the relevant norms. Fiber optic cable should not be affected by interference, electric corrosion this piece without taking into account? More: Cable can be parallel with the 10kV power cable laying, there is no distance requirements, two cables walking in a metal bridge is no problem. Fiber optic cable is through the optical communication, the power line of electromagnetic waves will not have an impact on it, there is no problem of electrical corrosion, because the cable is protected by an outer sheath. Now in the high-voltage cable directly attached to the internal fiber and power supply and communication, but also in the high-voltage overhead lines directly on the composite fiber (OPGW), while the power supply and power grid communication. Fiber optic cable, is a certain number of fiber in accordance with a certain way to form a cable core, outsourcing jacket, and some also cover the outer cover, used to achieve optical signal transmission of a communication line. Generally consists of cable core, reinforced steel wire, filler and jacket and other parts of the composition, as well as the need for waterproof layer, buffer layer, insulated metal wire and other components.

Q: I'm thinking of the power cables that connect houses to the national grid in the UK. Not only do they appear to be the green colour of copper in full sunlight, but this colour isn't evenly spread. In places there is still black. What causes this, as it's presumably not exposed copper or the colour would always be apparent?: This could simply be moss / lichen or fungus growing. the north side of the cable will have more moss on it than the south side. As the sun is over the equator and England is in the Northern Hemisphere so the sun lights the south side of the cable, and the moss grows on the darker side. This is a classic way of telling directions in a forest or paddock. Garret

Q: Asus Motherboard: P7P55D-E ProIntel CPU: Core i5-750 Quad-Core Desktop LGA1156BFG Tech Video Card: Nvidia GeForce 9800 GT 512 MBPower Supply: Thermaltake TR2 600WRAM: PNY 2GB DDR3 PC3-10666 1333MHzHD: Seagate 320GBTitle says it all. I've google my heart out looking for answers. Many say maybe power supply is bad. I tested my old PS and it still doesn't work. Try new Cable. Try every RAM slot. Made sure my CPU is nice and tight. Sigh...headache....headache.: You might want to look at Asus website under CPU support..the 750 shows 2 different bios up dates with a URL to go to for more Info. If that's all right..try the ram...(if its dual channel) take out one stick at a time see if you have a bad stick...if you only have one 2GB it may be bad...Go to BIOS and set to safe default then try it

Q: I am trying to find a 4 Pin Fan Power Splitter Cable or my computer since I only have 1 4 Pin Fan Power jack and I want to use 2 4 pin fans. I am having a really hard time trying to find one in hamilton: Before hooking that up, check the specs on your motherboard to see if that fan header will support loads from both fans. You may need to get a Molex to 4-pin converter and power directly off your power supply.

Q: I have a hp laptop from south asia. The adapter connects with the laptop and the power cable. The power cable has a 3 round pin plug which says 6A 240V~. On the hp adapter for the input it says: 100-240V~ 1.6A 5-60Hz. It also says Connect Only to Grounded outlets.Now I am in canada. All i know is that here they have 120 V in normal power plugs. Also they have 1 round and 2 rectangular pins to plug in the outlet.I bought this adapter which basically connects the 3 round pin plug into the adapter and the adapter has 3 canadian pins. The thing is that it says 250V 10A on the adapter. So I am not sure if it will hurt my laptop if I use it. I am a bit confused because Canada has 120V and the adapter accepts 250V. The HP adapter has a range from 100-240V. Will this be ok to use since the HP adapter will just convert the 120V into the proper output for the laptop or do I need one the expensice Voltage converters for the laptop?: It is fine, your power cable has a power rating of 6A @ 240V and your hp adapter can handle an input of 100-240V~ 1.6A 50-60Hz right? Then, you bought an adapter which has 10A 250V capacity and it is no problem handling your cable and hp adapter which has a lower power requirement. And also, the most important, in your area, the supply is 120V and your hp can handle from 100-240V and your adapter up to 250V, so there is nothing to worry about, as long as the supply voltage is lower than of the required of your hp, mind it if your supply voltage is 240V and your hp says it handles 120V for it will burn your adapter..............

Q: I have a feeling my power quot;brickis faulty and need to find a replacement, hopwever, none of the high street retailers quot;Game, Gamestation, HMV, Argosseem to stock them.: u can contact microsoft talk to them on teh phone for 5-10mins and theyll giv u a free one

Q: Electrical equipment installation project "power cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area, such as 3 × 25mm2 refers to 25mm. 75mm2 or cable cross-sectional area of 490mm2? More: Calculation method: the amount of engineering calculation formula: L = (pipe length calculation + wire reserved length) × with the number of cross-section wire. Note: plastic pipe should not be flattened, cracks, no debris in the tube, cut the mouth should be flat, the nozzle should be shaved plastic wire pipe connection using glue bonding, plastic pipe bonding must be tightly tight, and in the pipeline plug on the plastic pipe plug, to prevent the paddle, plug tube concrete floor, wall and brick structure of the various switches, socket bottom box , The lamp junction box and the pipe connection must be connected with the wiring, is strictly prohibited plastic pipe directly into the junction box dark in the concrete junction box requirements with wet cement paper or plastic foam filled with internal, not allowed to use The cement paper packs its outside. Embedded in the floor, the shear wall of the plastic pipe, the junction box should be fixed firmly to prevent the shift

Q: I have a ZXi8008 and there's a cable that goes out to the head unit to turn on the amplifier, which is different than the power cable. But in this car, i have not installed a new head unit. Where do I hook up this cable otherwise? It needs a constant power supply to be on.: i would hook it up to the power cable from ur stero that whay the amp will only come on when the radio comes on. that way u wont drain ur battery, thats if ur talking about the remote cable

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.: The cable that is laid on the ocean floor is typically called a submarine cable. These cables have been around for decades and were at first solid conductor cables used for telephone communications. Today they are typically a fiber optic cable with a solid conductor in the center. Typical burial rated fiber cable today can go 100km or about 60 miles in between repeaters. The cables are typically connected on either end by landing stations. These landing stations also provide power feed equipment. The repeaters are powered by a constant current sent down the conductor near the center of the cable. Therefore all repeaters in a cable are in series i.e. one wired to the next and to the next and so on. The landing station on one end of the cable will send a positive current and the station on the other end will send a negative current. The repeater derives it's power from the potential difference drop across them. This is basically a two channel power circuit wired in series using the same conductor...sorry to get really techincal=) isn't the internet great...hope this answers your question...below is a link to the patent applied for regarding transoceanic fiber repeaters, a submarine cable map, and my business website.

Q: How many amphs does the us ps3 slim's power cable have? It should be #A?: i don't know why youre trying to find this out but heres a chart. The power cable has different electricity usages depending on what youre doing but the average is 87 ish
