SNOW ADHESION PREVENTIVE TYPE LOW WIND NOISE WIRE

PURPOSE:To improve snow adhesion preventive effect by increasing the diameter of a wire of the same direction winding rod larger than that of a spiral rod of reversely winding to the twisting direction of the wire (or increasing the number of attachment in a circumferential direction or shortening its winding pitch) to increase a generated lifting force, and increasing the winding length of the rod crossing perpendicularly to its twisting direction. CONSTITUTION:The diameter of an S-direction winding rod of a spiral rod 2 wound on the outer periphery of a S-twisted wire 1 is formed largely than that of a Z-direction winding rod. In order to balance a lifting force generated by the S-direction winding rod with a reverse lifting force by increasing the reverse lifting force due to its increase caused by its large diameter, the spiral rod is wound in length l in the S direction, while the S-direction aiding rod is wound in length 3l in the Z-direction. Thus, the Z-direction winding part perpendicular to the S-twisted wire can be increased in its length, thereby increasing the length of a zone effective in prevention of snow adhesion.
