<p>PURPOSE:To always hold between phases at a predetermined interval against wind load in all directions by coupling aerial transmission lines therebetween by interphase spaces of two different types of bendable directions. CONSTITUTION:Two types of interphase spacers of a first type interphase spacer 2 of a structure bendable in a direction of a plane including adjacent aerial transmission lines 1 and scarcely bendable in the direction except the bendable direction and a second type interphase spacer 3 of a structure bendable in a direction perpendicular to the plane including the adjacent lines 1 and scarcely bendable in the direction except the bendable direction is employed. At least a pair are present between the same diameter to connect the adjacent lines 1 therebetween. Thus, the lines can be always held at a predetermined interval between the phases against wind load in all directions, thereby preventing the lines from abnormally vibrating.</p> |
