Core wire of reinforced stranded wire, wire core of reinforced twisted wire, and reinforced type stranded wire

Abstract

The invention provides a core wire of a reinforced stranded wire, and solves the technical problem of easy cracking and breaking of the existing stranded wire used in an earthquake region, a wind gapregion and other special regions. The core wire comprises one core strand and at least one layer of side wires uniformly stranded on the periphery of the core strand; the core wire is characterized inthat the core strand is stranded by more than two core lines; and gaps are formed between at least a part of adjacent side wires of the side wires on the same layer. In addition, the invention also provides a wire core of the reinforced stranded wire, and the reinforced stranded wire.

Description

technical field [0001] The invention relates to a stranded wire, in particular to a core wire of a reinforced stranded wire, a core wire of a reinforced stranded wire and a reinforced stranded wire. Background technique [0002] The stranded wire includes a wire core and an insulating sheath covering the wire core. The wire core is generally formed by twisting multiple strands of core wire. There is one layer, and the side wires of each layer are tangent to each other. In some special environments, such as earthquake areas or tuyere areas, the strands shake and swing frequently, and adjacent side wires produce severe friction, and the side wires are damaged. Cause twisted wire to break easily, once the twisted wire breaks, it will cause unpredictable damage to the safety of equipment operation and the safety of the people. Contents of the invention [0003] In view of the above problems, the present invention provides the core wire of the reinforced stranded wire, which c...
