Problems solved by technology

The metal material of the metal interlocking armor layer can be copper tape, steel tape or aluminum alloy tape. The cost of using copper tape armor is too high, and it is not suitable for large-scale promotion, while steel tape has high strength, poor toughness, and is not easy to process. , especially this kind of chain processing, and the steel belt is not corrosion-resistant, heavy, and not resistant to electromagnetic interference

Abstract

The invention discloses an aluminum alloy material for a metal linkage armored cable. The aluminum alloy comprises the following components based on percentage: 0.5-3 wt% of Fe, 0.1-1.5 wt% of Mg, 0.2-1 wt% of Cu, 0.2-1 wt% Si, 0.05-1 wt% of Zn and less than 0.5 wt% of B and further comprises one or at least two of Ti, Mn, V and Cr with a total content of not more than 1 wt%, and the balance of aluminum and unavoidable impurities. The aluminum alloy material is prepared by smelting, strip-casting, strip-extruding and thermal aging treatment; the prepared aluminum alloy has higher tensile strength and better ductility; the aluminum alloy material for a cable armored material has higher compressive strength and dynamic resistance; and the mechanical strength of an armored protective layer is remarkably increased.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric wires and cables, and in particular relates to an armoring material for cable armoring. [0003] Background technique [0004] Metal chain armoring is a new type of armoring method, which has changed the traditional armoring method. The adjacent layers of the armoring tape can realize self-locking interlocking, so this armoring method has greatly changed the steel tape armoring method. The defects of the equipment are eliminated, and the performance is better. The metal material of the metal interlocking armor layer can be copper tape, steel tape or aluminum alloy tape. The cost of using copper tape armor is too high, and it is not suitable for large-scale promotion, while steel tape has high strength, poor toughness, and is not easy to process. , especially this kind of chain processing, and the steel belt is not corrosion-resistant, heavy, and not resistant to electromagnetic interfe...
