Abstract

The invention discloses an aluminum alloy conductor flexible cable and a preparation method thereof, and belongs to the field of flexible cables. The aluminum alloy conductor flexible cable comprisesone or more cabling sheath layers, a cabling and belting layer and conductor insulating wire cores from outside to inside in sequence, wherein the number of the conductor insulating wire cores is oneor more, cabling fillers are filled between the conductor insulating wire cores, and each conductor insulating wire core sequentially comprises a tensile strand, an aluminum alloy conductor and a wirecore insulating layer from inside to outside. The aluminum alloy conductor flexible cable not only has high conductivity, but further has excellent tensile strength and compressive creep resistance,the possibility of replacing copper with aluminum in the flexible cable is realized, the use cost of the flexible cable is reduced, and the wear resistance and the service life of the cable are improved due to light weight and excellent characteristics.

Description

technical field [0001] The invention relates to the field of flexible cables, in particular to a flexible cable with an aluminum alloy conductor and a method for preparing the cable. Background technique [0002] The cable industry usually uses copper as a conductor. Copper is the second largest strategic reserve material after oil. However, my country is seriously short of copper mine resources and is a country that uses copper. The safe and sustainable supply of copper raw materials has become a very important strategic issue. . [0003] Because the melting point of aluminum (660°C) is much lower than that of copper (1083.4°C), the industrial smelting of aluminum alloy materials greatly reduces the consumption of high energy-consuming resources such as coal and electricity, reduces greenhouse gas emissions, and promotes the harmonious development of social economy and ecological environment . Replacing copper with aluminum alloy has advantages in terms of technical indica...
