This article provides an impact of applying physics and engineering modern techniques for electric power transmission improvement. Since power losses is a problem in present power systems, many concerns about how to minimize it. Nanotechnology is one of these new techniques and it is also a fastest growing field in research and technology. The main interest of nanotechnology is not electrical power engineering only but there were a lot of possible applications to improve electrical, mechanical, thermal or chemical properties of electric power equipment. This paper illustrates a new application of nanotechnology in electrical power transmission that appeared in coating the transmission lines of type ACSR with a nano layer of copper to minimize the resistance of the transmission and so minimize the transmitted power losses. The substrate used in our experiment was made of aluminium with purity of 99.9 % of dimensions 3×6×0.5 cm. The coating process was done by Hybrid Physical Vapor Decomposition by using DC magnetron sputtering technique. Tested the resistance of the coated substrates is reduced and the obtained results have proven the desired goal of power loss reduction in transmission lines.
