2022-03-02
In the modern era of advanced science and technology, many modern industrial facilities have appeared in our world and exist in our lives. Steel-reinforced aluminum strands also play an important role in electricity.
In the modern era of advanced science and technology, many modern industrial facilities have appeared in our world and exist in our lives. Steel-reinforced aluminum strands also play an important role in electricity.
The inner side of the ACSR is the steel core, and the outer side is wound around the steel core by the aluminum wire through stranding. The steel core mainly plays a role in increasing strength, and the aluminum stranded wire mainly plays a role in transmitting electric energy.
The steel core aluminum stranded wire has simple structure, convenient erection and maintenance, low line cost, large transmission capacity, which is conducive to laying across rivers, valleys and other special geographical conditions, good conductivity, sufficient mechanical strength, high tensile strength, and increase The tower spacing and other characteristics. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
Steel core aluminum stranded wire is mainly composed of steel wire and aluminum wire, which is mainly used for overhead line of power transmission. Among them, the main function of the aluminum wire is to transmit power, and the important function of the steel wire is to strengthen the firmness and strength of the line.
The steel core aluminum stranded wire tool has the advantages of simple structure, convenient erection and maintenance, low line cost, large conveying capacity and long distance, and is also conducive to the erection of special geographical conditions such as rivers and valleys. It has the characteristics of good conductivity, sufficient mechanical strength, tensile strength and increased tower spacing. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
What are the precautions during the use of ACSR? Pay attention to the voltage it can reach or withstand. Before purchasing or installing, you should fully understand the voltage and current that need to be transmitted, and then choose the model that matches it. Secondly, the safety problem in the installation process is also very important, because it is usually used in the transmission project of overhead lines, so professional installers are required to install according to the time, which can not only ensure the safety of personnel in the installation process, but also install reasonably, and design the safe distance from buildings or trees in advance.
When installing and using ACSR, only by fully considering the details of all aspects can the normal transmission of power and the safety after installation be guaranteed. For high-voltage transmission lines, it is impossible to place multiple lines on one route due to the limited routing of the lines. People came up with a line, a set of iron towers, and a method of hanging multiple lines, that is, one line is equivalent to multiple lines. For 500KV transmission lines, China mostly adopts the four-wire hanging method, known as the same tower and rack.
The steel core aluminum stranded wire has simple structure, convenient erection and maintenance, low line cost, large transmission capacity, which is conducive to laying across rivers, valleys and other special geographical conditions, good conductivity, sufficient mechanical strength, high tensile strength, and increase The tower spacing and other characteristics. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
The above are some knowledge points about ACSR. I hope you can seriously study and understand the relevant knowledge and choose the products suitable for your needs.
