Different Types of Cables

Key Difference:
There are four different types of cables: aluminium cables, copper cables, industrial cables and fiber optic cables.

Wires and cables play in important role in today’s world where everything runs on electricity. Without electricity, the world plunges into darkness where phones cannot be charged and lamps don’t function. All our basic necessities include using electricity. In order for the electricity to power equipment, one requires cables.

There are many different types of cables that can be found based on their application. These cables are often distinguished based on their make. There are four major types of cables that are used: aluminium, copper, industrial and fiber optic.

Aluminum Cables

Aluminum cables can often be found when dealing with electricity, because of their high conductive nature. These cables are ductile, light weight, non-magnetic and are perfect for heavy-duty applications. It is also eco friendly since aluminum can be recycled. These cables are used in motors, electric lights and even telephone lines.

Copper Cables

Similar to aluminum cables, copper cables are also highly conductive, ductile, lightweight and flexible and are commonly used in major electrical segments such as mining, electronics, transportation, and telecommunication. Because of their usage in the telecommunication sector, they are also known as Telecommunication Cables. These cables are used in microwave ovens, integrated circuits, electromagnets, electrical bus bars, electrical switches, etc.

Industrial Cables

Industrial cables are high duty cables that require being able to withstand extreme temperatures and are often used in chemical plants, oil refineries, aviation, pharmaceutical companies, etc. These cables are able to resist flames, chemicals, grease, etc. There are various different types of cables that have been created depending on the sector where it is used. These include Coaxial Cables, Armored Shielded Instrumentation Cables, Control Cables and several other Industrial Power Cables.

Fiber Optic Cables

Fiber optic cables are fairly new in the cable sector and is made with one or more translucent fibers that are covered with a protective jacket. Cables with a single fiber is known as Simplex Fiber Optical Cables, while one with two fibers is known as Duplex Fiber Optical. Cables with three or more fibers are labeled as Multi-Fiber Optical Cable. These cables are used in the telecommunication and computer sector because of its ability to send and receive data quickly.

There are many more different types of cables, but they are often classified under these four main categories.

Difference between UPA GST and NDA GST
Why BJP / opposed GST in UPA regime?
Till the last discussion of GST under UPA in November 2013, the states had some major demands:
1. Keeping Petroleum out of GST ambit
2. Keeping Alcohol out of GST ambit
3. Keeping Entry Tax out of GST ambit
4. Some sort of guarantee from Centre for potential revenue loss
The rationale behind these demands is quite understandable. GST wipes out most state-level indirect taxes, thus taking out one of the major source of revenues for states. It is like a parent tells a child to stop earning from today, and instead promises him a sum of pocket-money. To have at least some financial independence in their hands, States asked for items like petroleum and alcohol (which have huge sales) to be kept out of GST, and also a guarantee from the Centre to offset their losses.
As explained by Spokesperson Priyanka Chaturvedi in her tweet,Chidambaram the then Minister never considered the states demands.
He even openly rejected the 1%
additional levy (which was mooted as a compensation to producer states). This obstinate stand of the UPA was the reason why although it had 10 years, it could never build consensus on GST.
How did the new NDA Government achieve consensus in less than 10 months, when UPA couldnt do it in 10 years? They agreed to the demands of the states. Out of the above 4 demands, 3 were accepted, and a bonus benefit was passed on to the state:
1. Petroleum was kept out of GST
2. was kept out of GST
3. A proposal was sent to law ministry to work out a “Constitutional Guarantee” to compensate states
4. And the Bonus: The power to states of levying additional 1% levy, for maximum 2 years, to help augment state revenues
This is why BJP states, which were opposing the old GST bill, along with non-BJP states, are now agreeing to the NDA’s GST bill, because their have been addressed.

strikes again with ! Old Rs 500 and 1000 notes are now legal as 90% black money recovered by
According to RBI’s report, more than 90% of the black money hidden in the Indian economy has been accounted for.

Prime Minister Narendra Modi took the by surprise when he banned old notes of Rs 500 and Rs 1000 on November 8, 2016. However, PM Modi’s master stroke has finally paid off as more than 90% of the black money has been recovered according to the Reserve Bank of India. The latest report revealed that demonetisation has helped recover 90% of the black money and this stunning news has led to the legalisation of the old effective from April 1, 2017. Starting Monday, people can claim their old Rs 500 and Rs 1000 notes with a copy of their Aadhar card and the cash deposit slip. This move has been termed as Remonetisation by PM Modi. This new move by the Prime Minister will come as a relief for many who have been struggling to find liquid cash.
The introduction of the Rs 2000 notes was more of a menace than help as finding change for the money was as difficult as finding an empty cab or rickshaw at peak timings. According to RBI’s report, more than 90% of the black money hidden in the Indian economy has been accounted for. This step is said to be immensely successful, and the central bank claims that some other secretive plans will recover the remaining money that Prime Minister Narendra Modi has. The path ahead to remove black money from the Indian economy is still unknown. However, the RBI governor, Urjit Patel, said that PM Modi has a plan as fool proof as demonetisation to curb the black money from our system. Mohan Bhagwat will be India’s 14th president! RSS Chief has been confirmed as next President of India.
The Indian economy is expected to grow in multiple folds as the old currency hit the market once again. The introduction of the new currency clubbed with the return of the old Rs 500 and Rs 1000 notes will increase the cash circulating in India, thereby giving the economy a boost. The high denomination notes of Rs 2000 will remain in circulation as of now. Considering there is no deadline to collect the old notes, it is expected that there will not be any long lines at banks in this phase of remonetisation!

: This news is completely a work of fiction that was designed to trick you! Considering it is April 1, we would like to you for successfully becoming an ! Happy Fools’ Day!

Nano-coating makes coaxial cables lighter

Rice University scientists replace metal with carbon nanotubes for aerospace use

Common coaxial cables could be made 50 percent lighter with a new nanotube-based outer conductor developed by Rice University scientists.

The Rice lab of Professor Matteo Pasquali has developed a coating that could replace the tin-coated copper braid that transmits the signal and shields the cable from electromagnetic interference. The metal braid is the heaviest component in modern coaxial data cables.

The research appears this month in the American Chemical Society journal ACS Applied Materials and Interfaces.

Replacing the outer conductor with Rice’s flexible, high-performance coating would benefit airplanes and spacecraft, in which the weight and strength of data-carrying cables are significant factors in performance.

Rice research scientist Francesca Mirri, lead author of the paper, made three versions of the new cable by varying the carbon-nanotube thickness of the coating. She found that the thickest, about 90 microns – approximately the width of the average human hair – met military-grade standards for shielding and was also the most robust; it handled 10,000 bending cycles with no detrimental effect on the cable performance.

“Current coaxial cables have to use a thick metal braid to meet the mechanical requirements and appropriate conductance,” Mirri said. “Our cable meets military standards, but we’re able to supply the strength and flexibility without the bulk.”

Coaxial cables consist of four elements: a conductive copper core, an electrically insulating polymer sheath, an outer conductor and a polymer jacket. The Rice lab replaced only the outer conductor by coating sheathed cores with a solution of carbon nanotubes in chlorosulfonic acid. Compared with earlier attempts to use carbon nanotubes in cables, this method yields a more uniform conductor and has higher throughput, Pasquali said. “This is one of the few cases where you can have your cake and eat it, too,” he said. “We obtained better processing and improved performance.”



Replacing the braided metal conductor with the nanotube coating eliminated 97 percent of the component’s mass, Mirri said.

She said the lab is working on a method to scale up production. The lab is drawing on its experience in producing high-performance nanotube-based fibers.

“It’s a very similar process,” Mirri said. “We just need to substitute the exit of the fiber extrusion setup with a wire-coating die. These are high-throughput processes currently used in the polymer industry to make a lot of commercial products. The Air Force seems very interested in this technology, and we are currently working on a Small Business Innovation Research project with the Air Force Research Laboratory to see how far we can take it.”

Co-authors are graduate students Robert Headrick and Amram Bengio and alumni April Choi and Yimin Luo, all of Rice; Nathan Orloff, Aaron Forster, Angela Hight Walker, Paul Butler and Kalman Migler of the National Institute of Standards and Technology (NIST); Rana Ashkar of NIST, the University of Maryland and Oak Ridge National Laboratory; and Christian Long of NIST and the University of Maryland.

Pasquali is the A.J. Hartsook Professor of Chemical and Biomolecular Engineering, chair of the Department of Chemistry and a professor of materials science and nanoengineering and of chemistry.

The research was supported by the Air Force Office of Scientific Research, the Air Force Research Laboratories, the Robert A. Welch Foundation, NIST, the National Science Foundation and a NASA Space Technology Research Fellowship.

Category 5 cables

commonly referred to as , is a pair cable for carrying signals. This type of is used in structured cabling for computer networks such as . The cable standard provides of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). Cat 5 is also used to carry other signals such as and video.

Category 5 vs. 5e Cables

The category 5e specification upon the category 5 specification by tightening some crosstalk specifications and introducing new crosstalk specifications that were not present in the original category 5 specification. The of category 5 and 5e is the same (100 MHz) and the physical cable is the same, and the reality is that most Cat 5 cables meet Cat 5e specifications, though it is not tested or certified as such.

Category 5e vs. 6

The category 6 specification improves upon the category 5e specification by improving response and tightening specifications and introducing more crosstalk specifications. The improved performance of Cat 6 is 250 MHz and supports 10GBASE-T (10-Gigabit Ethernet).

ISRO's big leap, embarks on launching !

Sunday, May 15, 2016

: For the very first time in its history, the Indian Space Research Organisation ( ) is actually growing wings as it embarks this month on a never before space flight that would make history.

The Indian space agency is all set to undertake the maiden launch of its very own indigenous version of a 'space shuttle', a fully made-in-India effort.

Today, a sleek winged body almost the weight and size of a sports utility vehicle (SUV) is being given final touches at Sriharikota awaiting the final countdown.

Yes, the powers abandoned the idea of a winged reusable launch vehicle but India's frugal engineers believe the solution to reducing cost of launching satellites into orbit is to recycle the rocket or make it reusable. at ISRO believe that they could reduce the cost of launching stuff into space by as much as 10 times if reusable succeeds, bringing it down to USD 2,000 per kg.

Very soon and if all goes well possibly before the monsoon sets in, India's space port at on the coast of the Bay of Bengal in Andhra Pradesh will witness the launch of the made Reusable Launch Vehicle - Technology Demonstrator (RLV-TD). This will be the first time ISRO will launch a space craft, which actually has delta wings and after launch it will be glided back onto a runway in the Bay of Bengal.

The RLV-TD is unlikely to be recovered from sea during this experiment as it is expected that the vehicle will disintegrate on impact with water since it is not designed to float. The purpose of the experiment is not to see it float but to glide and navigate from a velocity five times higher than the speed of sound onto a designated virtual runway in the Bay of Bengal some 500 km from the coast.

Very similar in its looks to the American space shuttle , the RLV-TD being experimented is a scale model which is almost 6 times smaller than the final version.

K Sivan, director of the Vikram Sarabhai Space Centre, THIRUVANANTHAPURAM , says, "These are just the first baby steps towards the big Hanuman leap."

The final version will take at least 10-15 years to get ready since designing a human rated reusable rocket is no kid stuff.

The only countries that have attempted operational flights of a space shuttle are America, which flew its space shuttle 135 times and then retired it in 2011 and since then it lost its capacity to send astronauts in space on American made rockets. The Russians made only a single space shuttle and called it Buran it flew into space just once in 1989. After that the French and Japanese have made some experimental flights and from available literature it seems the Chinese have never attempted a space shuttle.

India embarked on making its own version of the space shuttle by thinking about it more than 15 years ago, but work in earnest it seems started only five years ago when a dedicated team of engineers and scientists plunged into making RLV-TD a reality. The 6.5-m-long 'aeroplane'-like spacecraft will weigh 1.75 tons and will be hoisted into the atmosphere on a special rocket booster.

The special or the first stage is powered using a solid fuel and it will hoist the RLV-TD experiment to about 70 km into the atmosphere from where the descent will begin. During the descent, phase which is essentially a glider like event small thrusters will help the vehicle to be navigated on to the exact spot where it is supposed to land.

Ships, satellites and will monitor its descent. The current experimental version has no undercarriage so it cannot be brought back onto land and India lacks a runway that is longer than 5 km in length to accommodate such a landing.

Some private billionaires with very support from have been trying to master vertical lift-off and vertical landing as part of trying to recycle engines.

is a company owned by South Africa-born Elon Musk which became big through the Internet economy and has been able to land its Falcon-9 rocket onto a sea-based platform.

On the same lines the company Blue Origin owned by Jeff Bezos landed its New Shepard rocket on land in Texas. Bezos, another billionaire, made it big by building the online trading platform.

In fact NASA chief General Charles Bolden, when he was in New Delhi recently, said the competition has shifted to a fight among billionaires to reduce the cost of launching satellites into space.

The making of the Indian space shuttle or RLV-TD has taken 5 years and the has invested Rs 95 crore in the project. This flight will test the capability of the vehicle to survive a re-entry at speeds higher than that of sound so it is called a hyper sonic experiment (HEX).

Later, in the next few flights the RLV will be subjected to a landing experiment and another return flight experiment. Once these are successful, ISRO will then decide on what should be the final configuration of the Reusable Launch Vehicle.

One key technology the scientists at VSSC had to was to make materials that can withstand the very very high temperatures that the exterior of the vehicle is faced with as it comes back into the dense after its journey through near vacuum in space.

The friction from the air turns the like a red-hot iron plate. To be able to withstand these 5000-7000 degrees Celsius temperature the scientists have developed very lightweight heat resistant silica tiles that are plastered on the underbelly of the so-called Indian space plane.

The nose cone takes the brunt of the high temperatures and is made up of a special carbon-carbon composite that can withstand high temperature. These special materials are necessary to protect the insides of the vehicle where the temperature should never go higher than 50 degrees Celsius.

In fact, it is these heat resistant tiles and thermal coating that failed on the American Space Shuttle, Columbia that resulted in the death of Indian born American astronaut Kalpana Chawla's in 2003. Consequently, ISRO has laid a lot of emphasis on the thermal management of the RLV.

After the successful deployment of the swadeshi Global Positioning System through NAVIC or Navigation with Indian Constellation, ISRO is again reaching for the stars.

Technology development is tough and space fairing is certainly not for the faint hearted and the 600 scientists and engineers who have toiled hard in making the RLV-TD a reality will be watching with baited breath if their baby succeeds.

Shyam Mohan, the project director from VSSC for this landmark experiment, says his team has spent sleepless nights in perfecting this new rocket but adds that space technologies are inherently risky.

So will ISRO succeed where other super powers have failed, Indians certainly hope for the best, as success has become a habit at ISRO.

May be sooner than later the RLV should be named the 'Kalamyaan' after India's legendary former President APJ Abdul Kalam, an aeronautics engineer par excellence who made top class rockets and dreamt big of India being propelled to become a developed country.

For ISRO, no dream is too big as it carefully forges ahead to have a fully 'swadeshi space shuttle'.ISRO's big leap, embarks on launching Indian space shuttle!
