'Attention', Development of high voltage transmission line' by professor Kwon Han-sang, PKNU.
- Contract with TAS Co., Ltd. for 'manufacturing CNT-aluminum transmission line' for transferring technology fee at 400 million won.
A high-voltage transmission line with a strength four times higher than that of a conventional aluminum high-voltage transmission line has been developed.
It is the "Carbon nanotube (CNT) -aluminum complex powder" developed by Professor Kwon of PKNU.
Professor Kwon made a seamless transmission-free composite wire by uniformly dispersing the carbon, which is ceramic on aluminum, by using the technique of grinding and mixing the raw materials to the size of nano (one nanometer is one billionth of a meter).
Compared to pre-existing aluminum used for high-voltage transmission lines, the complex wire has a tensile strength of 4 times and a hardness of 20 times or more superior to the same surface area.
Professor Kwon said, "The existing aluminum high-voltage power transmission line reinforced the strength by inserting steel wire into the center of it, so there was a problem that the transmission tower had to be tightly installed in order to prevent slag due to weight. It is expected to reduce the number of power transmission towers as well as reduce cost and environmental damage by eliminating iron wire and creating light high-voltage transmission lines. "
Professor Kwon completed development of prototype applying this technology and completed patent registration recently.
"The composite wire developed at this time has sufficient tensile strength compared with copper used in general wires and it weighs only one-third, so it can be applied to industrial wires for automobiles to lighten weight," he added.
He signed a technology transfer contract with TAS (representative Jang Min-woo, Kyungbuk Gyeongsangnam-do) in the meeting room of the 5th floor of the Hanmir building in the Yongdang campus on Oct.,19 to receive 400 million won for the technology fee.
TAS Co., Ltd., a manufacturer of extruding aluminum bars, plans to apply this technology to produce high voltage wires and electric wires for electric vehicles. <Pukyong today>
