Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0017] The present invention provides an aluminum alloy diameter-expanding wire used for overhead transmission lines. The entire aluminum alloy diameter-expanding wire type is a comb-twisted type, including multiple layers of twisted wires arranged in turn from the inside to the outside. It is a stranded wire layer wound by LHA1, LHA2 high-strength or LHA3 medium-strength aluminum alloy S, Z or T-shaped monofilament, and other stranded wires within the outermost layer are all wound by LHA1 or LHA2 high-strength aluminum alloy round monofilament strand layer. The outermost layer is made of LHA1, LHA2 high-strength aluminum alloy or LHA3 medium-strength aluminum alloy stranded wire. Compared with the conventional steel c...

Abstract

The invention discloses an aluminum alloy diameter-expanded wire for an overhead transmission line. The whole aluminum alloy diameter-expanded wire is of a combed type, and comprises four layers of stranded wires, respectively being a first layer of stranded wires, a second layer of stranded wires surrounding the first layer of stranded wires, a third layer of stranded wires surrounding the secondlayer of stranded wires, and a fourth layer of stranded wires surrounding the third layer of stranded wires in sequence from inside to outside. The first layer of stranded wires, the second layer ofstranded wires, and the third layer of stranded wires are all stranded wire layers wound by LHA1 or LHA2 high-strength aluminum alloy round monofilaments; and the fourth layer of stranded wires is a layer of stranded wires wound by LHA1, LHA2 high-strength or LHA3 medium-strength aluminum alloy S, Z or T type monofilaments. The aluminum alloy diameter-expanded wire overcomes the defects such as pressure deformation, hopping and the like of the existing diameter-expanded wire in the crimping process.

Description

technical field [0001] The invention relates to a conductor for overhead transmission lines, in particular to an aluminum alloy diameter-expanding conductor for overhead transmission lines, and belongs to the technical field of conductors for overhead transmission lines. Background technique [0002] Expanded diameter wire is a type of wire that can increase the outer diameter without increasing the effective cross-section. At present, domestic conventional expanded diameter wires are comb-twisted steel core expanded aluminum stranded wires, the inner core of which is steel core (mainly used to bear the tensile force), except for the steel core part, it is 61.0% IACS duralumin round wire (Mainly used for conducting electricity), the wire is formed by drawing strands from the middle aluminum part based on the steel-cored aluminum stranded wire. [0003] According to construction experience, due to the lack of strands in the middle of this type of wire and the poor compressiv...
