The recessed edge of the convex edge of left side bearing and right side bearing is has the curve that once turns round at least.
The recessed edge of the convex edge of left side bearing and right side bearing is has the once broken line of turnover at least.
Between upper sideline and left side bearing, the right side bearing, and be arc transition between lower sideline and left side bearing, the right side bearing.
Thickness 〉=the 0.1mm of aluminium coating layer.
Second kind of technical scheme that the utility model adopts is: a kind of aluminium-clad steel wire comprises steel core and is coated on the aluminium coating layer of steel core periphery that the outer contour of the section of aluminium coating layer has and is concentrically ringed upper sideline and lower sideline; The outer contour of the section of aluminium coating layer has with the left side bearing on recessed edge with the right side bearing on recessed edge or have the left side bearing of band convex edge and the right side bearing of band convex edge.
The recessed edge of left side bearing and the recessed edge of right side bearing are circular arc line and are symmetry with the mid point line of upper sideline and lower sideline, and perhaps the convex edge of the convex edge of left side bearing and right side bearing is circular arc line and is symmetry with the mid point line of upper sideline and lower sideline.
The recessed edge of left side bearing and the recessed edge of right side bearing are broken line and are symmetry with the mid point line of upper sideline and lower sideline, and perhaps the convex edge of the convex edge of left side bearing and right side bearing is broken line and is symmetry with the mid point line of upper sideline and lower sideline.
Between upper sideline and left side bearing, the right side bearing, and be arc transition between lower sideline and left side bearing, the right side bearing.
Thickness 〉=the 0.1mm of aluminium coating layer.
Aluminium-clad steel wire behind the employing said structure, adjacent Unit two concavo-convex matching, behind the concentric stranding between the adjacent aluminium-clad steel wire the little cooperation in gap tight, when the disconnected thigh of the outer quilt thunderbolt of twisted wire, be difficult for broken lot, therefore increased anti-thunderbolt performance, closely be not easy because hydrops corrodes or icing owing to cooperate, thereby prolonged useful life.
