Abstract

The invention discloses a flexible cable with an aluminum alloy conductor and a preparation method thereof, belonging to the field of flexible cables. The flexible cable includes one or more layers of cable sheath layers, cable wrapping layers and conductor insulation in sequence from outside to inside. Wire core, the conductor insulated core is one or more strands, each conductor insulated core is filled with a cable filler, and the conductor insulated core includes tensile strands, aluminum alloy conductors and Core insulation. The flexible cable of the present invention not only has high electrical conductivity, but also has excellent tensile strength and compressive creep resistance, realizes the possibility of replacing copper with aluminum in flexible cables, reduces the cost of using flexible cables, and improves the performance of the cable due to its lightweight and excellent characteristics. Abrasion resistance and service life.

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...
