Anti-vibration steel-cored aluminum stranded wire

Abstract

The invention relates to the technical field of related structures of steel-cored aluminum stranded wires, and discloses an anti-vibration steel-cored aluminum stranded wire, which comprises a steel-cored aluminum stranded wire body and a flexible buffer layer. The steel-cored aluminum stranded wire body comprises a steel core wire, an inner aluminum stranded wire and an outer aluminum stranded wire. The annular wire of the steel core wire is provided with inner spiral embedding path grooves matched with the inner aluminum stranded wire, the inner aluminum stranded wire is connected with the steel core wire in a spiral embedded mode through the corresponding inner spiral embedded path grooves, and the flexible buffer layer wraps the inner aluminum stranded wire in an annular mode. According to the anti-vibration steel-cored aluminum stranded wire, different from a traditional mode in which a steel wire is directly and spirally wound by an aluminum stranded wire, the inner aluminum stranded wire is spirally wound in the inner spiral embedding path groove, so that the inner aluminum stranded wire is embedded on the steel core wire, the outer aluminum stranded wire and the flexible buffer layer are flexibly and spirally wound, the connection integrity between structures is improved, and therefore, the vibration resistance of the steel-cored aluminum stranded wire structure is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of structures related to steel-cored aluminum stranded wires, in particular to an anti-vibration type steel-cored aluminum stranded wire. Background technique [0002] Aluminum-steel-reinforced wire refers to a reinforced conductor in which single-layer or multi-layer aluminum strands are twisted outside the galvanized steel core wire. It is mainly used in the electric power and transmission line industry. The aluminum steel cored wire is made of aluminum wire and steel wire twisted. It is suitable for overhead transmission lines. It has a steel "core" inside and an aluminum wire through twisting on the outside. The steel core is mainly used to increase the strength, and the aluminum stranded wire is mainly used to transmit electric energy. When the steel-reinforced aluminum stranded wire is erected for a long distance to transmit current, the steel-reinforced aluminum stranded wire is vulnerable to airflow ...
