Corning Fiber won Technology and Engineering Emmy Award
OFweew: Corning announced that it won the Emmy Award for Technology and Engineering from the National Academy of Television Arts and Sciences for its invention of low loss fiber in 1970.
The award is mainly awarded to breakthrough innovative technologies that affect television engineering. Corning won the Fiber Optic Cable Pioneer Invention and Deployment Award at the 68th Technology and Engineering Emmy Awards in Las Vegas. Also receiving this award was Bell Labs/Western Electric (OFS). In addition, Telcon (Alcatel-Lucent Networks) received the Emmy Award for Optoelectronic Conversion Concept for Technology and Engineering.
"The ability to view high-quality video from anywhere on a variety of connected and mobile devices at any time of the day is commonplace today. But this is impossible without the widespread deployment of fiber." Corning implemented Deputy President Klink Kimlin said. "If you do not have the actual infinite bandwidth capability of fiber, you can't imagine what the television industry will be like today. It was born in Corning Labs in 1970. Until now, our scientists have never stopped improving."
Decades ago, Corning scientists Dr. Robert Maurer, Donald Keck and Peter Schulz developed the first low-loss fiber that can hold laser signals over long distances. This breakthrough helped solve the problem of increasing the amount of information handled by network operators, as well as the copper transmission restrictions. As the data travelled at the speed of light, this invention enabled scientists to win numerous awards, including the invention of the National Science Medal in 2000, which led to a communications revolution.
Today, fiber bandwidth can transmit two million HD video at the same time, which is an ideal driver for the advancement of high-speed communications. Because wireless signals must be interconnected with the network, fiber is also a key element in a world where streaming media has become the norm.
Kinlin said. “We are very grateful to the National Academy of Television Arts and Sciences for their recognition. We will always be committed to bringing glass-related innovations into the evolving communications and entertainment industry.”
About power cable
Power cables are cables used for transmission and distribution of electrical energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply for industrial and mining enterprises, and power lines under the sea.
In power lines, the proportion of cables is gradually increasing. The power cable is a cable product for transmitting and distributing high-power electric energy in the trunk line of a power system, including various voltage levels of 1-500 KV and above, and various insulated power cables.
The use of power cables has been more than 100 years old. In 1879, the American inventor T.A. Edison wrapped jute on a copper rod and penetrated it into an iron tube, which was then filled with asphalt mixture to make a cable. He laid the cable in New York and started underground transmission. The following year, the British Mr. Callander invented asphalt-impregnated paper-insulated power cables. In 1889, British S.Z. Ferranti laid 10 kV oil-impregnated paper insulated cables between London and Detford. In 1908, Britain built a 20 kilovolt cable network. Power cables are increasingly used. In 1911, Germany laid 60 kV high voltage cables and began the development of high voltage cables. In 1913, the German M. Horcheste developed the phase-shielded cables to improve the distribution of the electric field inside the cable and eliminate the tangential stress on the insulation surface, which became a milestone in the development of power cables. In 1952, Sweden laid a 380 kV EHV cable at the northern power plant to realize the application of ultra-high voltage cable. In the 1980s, 1100 kV and 1200 kV UHV power cables were manufactured.
Divided by voltage level
According to the voltage level can be divided into medium and low voltage power cable (35 kV and below), high voltage cable (110 kV and above), ultra high voltage cable (275 to 800 kV) and UHV cable (1000 kV and above). In addition, it can also be divided into AC and DC cables by current. high voltage cable gel
Classified by insulation material
1. Oil-impregnated paper-insulated power cables are insulated with oil-impregnated paper. Its application has the longest history. It is safe, reliable, long-lasting, and inexpensive. The main disadvantage is that the laying is limited by the drop. Since the development of non-dripping impregnated paper insulation, the problem of drop restriction has been solved, and the oil-impregnated paper insulated cable has continued to be widely used.
2. Plastic insulated power cable The insulating layer is an extruded plastic power cable. Commonly used plastics are polyvinyl chloride, polyethylene, cross-linked polyethylene. The plastic cable has a simple structure, is convenient to manufacture and process, light in weight, easy to install and install, and is not limited by laying gaps. Therefore, it is widely used as a medium and low voltage cable and has a tendency to replace the adhesive impregnated oil paper cable. Its biggest drawback is the presence of dendritic breakdown, which limits its use at higher voltages.
3, rubber insulated power cable Insulation for the rubber with a variety of compounding agent, after fully mixed and extruded on the conductive core, after heating and vulcanization. It is soft, flexible, and suitable for applications that require frequent movements and small bending radii.
Commonly used as insulation material of natural rubber - styrene-butadiene rubber mixture, ethylene propylene rubber, butyl rubber and so on.
