難着雪型架空電線。Regarding the plane of a tape-like sheet 3 having a width πd that is to be wound longitudinally around the outer periphery of an overhead electric wire having an outer diameter d, an appropriate constant a is set on both edge lines j1 and 32 extending in the longitudinal direction of this tape-like sheet 3. Points lined up at intervals, A work, A2.
A3. ...B1. B2. B3. ..., but also points C□, C2, C3゜, which are arranged at positions shifted by z in the longitudinal direction from the points on the center line XX, which is parallel to the edge lines and equidistant from them. is set,
Therefore, on the plane of the tape-like sheet 3, a quadrilateral A1C1BiC2°A2C2B2C5,A is formed by connecting these points.
3C3B3C4, .
2C5, . . . there are triangles between them AlC2A2. A2
C3A3. ..., and triangle BIC2B2. B2C
3B3. A plurality of triangles similar to ... are set so as to form a symmetrical pattern with respect to the center line XX, and the width is set as appropriate corresponding to the positions of all the sides of all the quadrilaterals and triangles set. A guide groove 4 is formed, and the tape-like sheet 3 is wrapped vertically in a cylindrical shape over the overhead electric wire having the outer diameter d, with the tape-like sheet 3 positioned almost directly above or directly below the center line xx in the vertical direction. This is an overhead power line that is characterized by the fact that it is snow-resistant.
