Weimports a complete set of optical passive device production assembly equipment and test equipment from

the United States and Japan, and set up optical passive device production lines. It will provide customers fiber

optical connectors such as FC, SC, ST, LC, MT-RJ and MU, and variety of pigtail and jumper products, single-mode / multi-mode and PC / UPC/APC for instance. Our patch cord are approval by Ministry of Information Industry with

telecommunications network access certification.

It accords with China standard GB/T12706, conductor section cross-area is below 500mm2 use copper tape to screen.
The conductor adopts the copper or aluminum wire that the standard required;
The conductor shield adopts extrusion shielding layer;
Insulation adopts very clear cross-linking material; insulation shielding adopts extrusion shielding layer;
Adopting triple extrusion
Bedding will be added if cable has armor, we have steel tape and steel wire armoring according to client’s specification.
Non-magnetic material be suggested in single core cable
Outer sheath generally use PVC

Q:I don't understand how oil and gas industry has anything to do with electrical engineering jobs??Am I not seeing this because currently I am working as a electronics engineer ? This is how I am thinking about this - Oil and gas industry , digs up oil , provides it to our cars and trucks so they can run. Now I don't understand how or where Electrical engineers come into play into this ?? Please make me understand. I want to know.P.s: I am an entry level electronics engineer, with a degree in Electrical engineering , Currently I am located in Houston, texas.: A great deal of electric power is used in extracting oil and gas from the ground, transporting it through pipelines, separating and refining the crude products and distributing the products. Electrical engineers design the required electrical equipment and the associated electric power distribution and control systems. In some situations, electric power must be generated on site rather than purchased from electric utility companies. In addition, electrical engineers are involved in the process instrumentation and control system design. The process control includes both computer systems and specialized electronic equipment.

Q:give formulas and explanation both: The input, output and efficiency relationships are the same. In one case we are talking about a mechanical system and in the other it's an electrical system.

Q:If it is, why?: we use this concept in order to bypass the fault currents, as we know that fault currents are of high frequency. and also the equivalent circuit of the earth is the parallel combination of the resistor and capacitor,also capacitor acts as short circuit(i.e of least impedance). Xc1/(2*pie*frequency*capacitance)

Q:Assuming that it is safe to do so as far as people not getting hurt, will it damage the electrical equipment?: To add to the first two good answers switches are designed specifically to make and break the rated current (and to do this many thousands of times without problem). If you simply pull the plug out of the wall, the break arcs occur in the wall socket which is not designed to do this thousands of times.

Q:i am going to ship my furniture including my electronics( refrigerator, recorder, laptop, dishwasher, drier, etc) i want to now if the voltage in USA is 240v as in Dubai or 110v and i case of difference i want your advice i`ll ship them or not: Kaed59, The usual problems of shipping GCC electonic and electrical equipment to the USA (NOT applicable to Saudi Arabia) is that the main power supply in USA is 110VAC as compared to the UAE - which is predominantly 220VAC (so you will be needing lots of transformer or a big transformer with a bigger wattage rating. But the biggest problem is actually the frequency (Hz). The US utilize a 60Hz frequency as opposed to the UAE, Bahrain, Oman, Qatar and Kuwait's 50Hz frequency (KSA use 60Hz). Hence, you will find in SOME of the electrical appliances and equipment as rated 90-230VAC 50-60Hz. These are universal appliances which can be used both in European (50Hz) and American (60Hz) power supply. Unless specified by the manufacturer to operate on either 50 or 60 Hz, appliances may not operate efficiently or even safely if used on other than the intended supply frequency. I would suggest you check before shipping them and dispose locally before you shipp to US. Good luck and have a safe journey !!!

Q:I have a piece of electrical equipment that uses a 12v DC in that i want to replace with a battery, as it currently uses a wall charger with an AC converter. How would i go about doing this for cheap? making it myself wouldn't be out of the question, all i need is a guide. The 12v pack must also be as small as possible, as it is powering a portable device.: It relies upon what form of battery it is. Lead acid batteries (vehicle batteries) are extremely indestructible, yet nonetheless incorrect charging could nicely be risky by way of fact it may launch hydrogen gas it extremely is a fireplace of explosion possibility in restricted area. Over charging at a extreme fee could additionally overheat the battery and bodily harm it. best is a appropriate battery charger. a inexpensive charger could fee no longer extra effective than a mains adaptor besides. For different varieties of rechargeable battery you easily decide for a appropriate battery charger, or you will harm the battery in a small form of expenditures (in the worst case, the 1st time you attempt to fee it). If the device is often used the place there's a mains poiwer furnish, why no longer basically use a DC adapter particularly of the battery? to respond to your particular questions a million) confident. 2) No. forget approximately with regard to the advice in yet another answer approximately restricting the present with a diode. in case you knew adequate to layout your person battery charger suitable, you probable does no longer be asking this question!

Q:I want to get into a field that involves fixing electrical equipment. I have always loved taking apart things like my Xbox/Playstation/cell phone so I could fixing them when they broke and I would like to further this into a career. What type of field should I study in order to pursue this goal? I am a student at the University of Arizona, so if you know of any programs there that would help a lot.: None, depending on how or where you work. If you work for yourself you don't need any degree at all. You need to be an electronics service engineer. You have to be able to do the job. That's more important than having a piece of paper that says you got good grades and showed up or class. (I would argue this is true for most fields) You can get a degree in electronics engineering at many schools. It would be very helpful to find work at a company specializing in service of these things. Nobody repairs cell phones, it just isn't worth doing.

Q:I have been doing some research in which stocks i would like to invest in. Well i found this company called Raser Technologies. Supposedly they are a geothermal electrical power plant company. With Obama's environmental laws that he is passing, will this cause this stock to increase? i dont know a whole lot about stocks or about this company but if they step up as a major alternative energy companies then they should bring in a lot of profit seeing as their stocks are now only at2.27 a share. any information about this company or predictions for the future of other alternative energy companies would be greatly appreciated. I really think that with all the searching of alternative energy sources, this would be a great investment for the future when these companies step up.: Wow, okorder

Q:Also how do we know our brain has electrical pulses. How do u prove it: the electrical current travels through neurons, brain cell, that never reproduce, ever. you are born with them. as to how to prove it. well the pulses are really fast, literally faster than a single thought or movement. but ever notice how you could reach for something with your hand and then move forward with your feet. that is your brain saying oh, okay I am too far, better take a step so I can reach. but the first wave was just the hand and the second wave was the feet. but both major waves took hundreds of smaller waves to communicate to get all the muscles moving your heart beating to make you move.

Q:I have two orange electrical outlets in my dorm and I want to plug things like my lamp, fan, phone charger, etc. into them. Is that safe?: Basically it says its a DEDICATED CIRCUIT ,DEDICATED GROUND
