송전용 구리코팅 알루미늄선{COPPER COATED ALUMINIUM CABLE FOR THE HIGH VOLTAGE TRANSMISSION LINE}Copper coated aluminum wire for power transmission {COPPER COATED ALUMINIUM CABLE FOR THE HIGH VOLTAGE TRANSMISSION LINE}

본 발명은 송전용 구리코팅 알루미늄선에 관한 것으로, 더욱 상세하게는 가공송전선로의 전력손실을 최소화하고 도체 저항에 의한 발생열의 열전도를 높혀서 발열효과를 증가시키고 열발생으로 인한 송전선의 이도(처짐)현상을 최소화하도록 하며 대기중 부식현상을 감소시킬 수 있는 송전용 구리코팅 알루미늄선에 관한 것이다.The present invention relates to a copper-coated aluminum wire for power transmission, and more particularly, to minimize the power loss of the overhead transmission line, to increase the heat conduction of the generated heat by the conductor resistance to increase the heating effect and the degree of deflection of the transmission line due to heat generation The present invention relates to a copper-coated aluminum wire for transmission that can minimize the phenomenon and reduce the corrosion phenomenon in the air.

기존의 송전선로에 널리 사용되고 있는 강심알루미늄연선(ACSR)은 도체의 소재와 구조상 전력손실률이 매우 높고 도체저항으로 인한 발열현상으로 인하여 송전탑간 선로의 이도(처짐)현상으로 인한 문제점이 발생되며 알루미늄의 화학적 부식변화에 따르는 송전선의 노후화에 따른 수명단축 현상에 주목하여 이들 문제점을 보완하되 경제적 비용을 기반으로 하는 새로운 방식의 송전선 개발이 필요하다.Steel core aluminum stranded wire (ACSR), which is widely used in existing transmission lines, has a high power loss rate due to the material and structure of conductors, and heat generation due to conductor resistance causes problems due to derailment of lines between transmission towers. It is necessary to pay attention to the shortening of the service life due to the aging of transmission lines due to chemical corrosion changes, and to solve these problems, but it is necessary to develop a new type of transmission line based on economic cost.

이러한 문제점들을 해결하기 위해 기존의 알루미늄 전선보다 도체저항이 적어 전력손실이 낮고 열전도성이 우수하여 발열효과의 증가로 인한 이도현상을 최소화 시키고 알미늄선의 표면부식을 늦추는 소재의 개발이 중요하다.In order to solve these problems, it is important to develop a material that has lower conductor resistance than conventional aluminum wires, has a low power loss and excellent thermal conductivity, thereby minimizing the degree of doubling caused by an increase in the heating effect and slowing the surface corrosion of aluminum wires.

즉, 도체에 교류가 흐를 경우 전류밀도가 중앙부에서 보다 그 표면에 가까워질수록 커지는 표피효과(Skin Effect)를 이용하여 알미늄 표피부분에 전기적 저항이 낮아 상대적으로 도전율이 높은 동(Copper)을 코팅(Coating)한 동복 알미늄선(Copper Coated Aluminium Wires)소재를 연선( Stranded Wire)하는 구조의 송전용 구리코팅 알루미늄선이 필요하다.In other words, when alternating current flows through the conductor, the copper skin is coated with a relatively high electrical conductivity due to its low electrical resistance, using the Skin Effect, which increases as the current density gets closer to the surface than in the center. Copper-coated aluminum wire is required for the structure of stranded wire coated with Copper Coated Aluminum Wires.
