　　 Specification and model supply of steel cored aluminum stranded wire JL/G1A-300/25

　　The function of steel cored aluminum stranded wire;

　　Steel cored aluminum stranded wire follows the GB/T1179-2017 standard

　　aluminum conductor steel reinforced (ACSR)It refers to a reinforced conductor in which a single or multiple layers of aluminum stranded wire are twisted outside a galvanized steel core wire. Mainly used in the power and transmission line industries.

　　 Steel cored aluminum stranded wire is used for high-voltage transmission lines. Due to the limited path of the line and the inability to install multiple lines on one path, people have come up with the method of using one path, one set of iron towers, and hanging multiple wires, where one line is equivalent to installing multiple lines; For 500KV transmission lines, China mostly adopts the method of hanging four wires, which is called the same tower parallel installation.

　　 aluminum conductor steel reinforced (ACSR)Steel cored aluminum stranded wire has the characteristics of simple structure, easy installation and maintenance, low line cost, large transmission capacity, and is conducive to laying in special geographical conditions such as crossing rivers and valleys. It has good conductivity and sufficient mechanical strength, high tensile strength, and the tower distance can be enlarged. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.

　　It has a steel "core" inside and an aluminum wire twisted around the steel core on the outside; The steel core primarily serves to add strength, while the aluminum stranded wire primarily serves to transmit electrical energy; For high-voltage transmission lines, due to limited routes and the inability to install multiple lines in one route, we have come up with the idea of using one route, a set of iron towers, and hanging multiple wires, where one line is equivalent to installing multiple lines; For 500KV transmission lines, China mostly uses the method of hanging four wires, which is called "four cut wire". Originally, these four cut wires were ordinary four steel core aluminum stranded wires, without any special features, not one made of steel and three made of aluminum; Corresponding to "bare" wires, there are also overhead insulated wires, mostly JKLYJ, which are overhead aluminum material cross-linked polyvinyl chloride encapsulated wires; It has been widely used in Chinese cities and distribution systems with high requirements for power supply reliability. Although the price is high, it is the development direction of distribution lines. Effect and advantages: Steel cored aluminum stranded wire has the characteristics of simple construction, convenient installation and maintenance, low line cost, large transmission capacity, and is conducive to laying across special geographical conditions such as rivers and mountain gullies. It has outstanding conductivity and mechanical strength, high tensile strength, and expandable tower spacing. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
