Mechanically, this prevents fatigue rupture due to stress concentration at the proximal end of the flexible jumper. [Structure] Flexible jumper parts 1B connected to the power transmission line main line 2 on both sides of the intermediate rigid jumper part 1A suspended below the tower arm 11 in a substantially horizontal state are connected to the power transmission line main line 2. It is composed of a stranded conductor 6 having a larger diameter and greater rigidity than the constituent stranded conductors. Since the stranded wire conductor 6 has a larger radius of curvature than before, its surface potential gradient becomes lower. In addition, as it becomes thicker and stiffer, it becomes less likely to cause lateral vibrations, etc.

【0004】 すなわち、送電線本線を構成する撚線導体と同一の撚線導体にて構成されてい る可撓性ジャンパ部は、その線径(導体の曲率半径)が小さくて細いので、電気 的には表面電位傾度が高く、そのため雨天時等においてコロナ放電に基づくAN 騒音(ラジオノイズやテレビノイズ)を発生しやすいものである。また機械的に は剛性が小さいために横方向風圧等を受けた際に大きく横振れしやすく、そのた め可撓性ジャンパ部の基端部が応力集中による疲労を生じて遂には断線事故に至 る恐れがある。0004 In other words, it is made of the same stranded conductor as the stranded conductor that makes up the main transmission line. The flexible jumper part has a small wire diameter (radius of curvature of the conductor) and is thin, so it is has a high surface potential gradient, and therefore AN due to corona discharge occurs in rainy weather etc. It is likely to generate noise (radio noise or television noise). Also mechanically Because of their low rigidity, they tend to sway significantly when subjected to lateral wind pressure, etc. Therefore, the proximal end of the flexible jumper becomes fatigued due to stress concentration, which eventually leads to a disconnection accident. There is a risk of

従来にも増して太い(曲率半径が大きい)撚線導体にて構成された可撓性ジャ ンパ部は、電気的には、その表面電位傾度が低減するのでコロナ放電が生じにく くなる。また機械的には、剛性が増大するので横振れ等が生じにくくなる。 A flexible jacket made of stranded conductors that are thicker than before (larger radius of curvature). Electrically, the surface potential gradient of the damper section is reduced, making it difficult for corona discharge to occur. It becomes.
