JL/G1A185/25 Price Power Steel Core Aluminum Stranded Wire Manufacturer State Grid Winning Bidder Welcome to Call

Description :

　　Main applications

　　For high-voltage transmission lines, due to the limited path of the line and the impossibility of installing 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, that is, 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.

　　Related advantages

　　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.

　　Core aluminum stranded wire

　　Discussion on the role and advantages of steel cored aluminum stranded wire

　　Steel cored aluminum stranded wire is made by twisting aluminum wire and steel wire, and is suitable for overhead transmission lines.

　　It has a steel "core" inside and is wrapped around the steel core with aluminum wire twisted together on the outside; Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy;

　　For high-voltage transmission lines, due to the limited path of the line and the impossibility of installing 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, that is, one line is equivalent to installing multiple lines; For 500KV transmission lines, China mostly adopts the method of hanging four wires, which is called "four split line". In fact, these four split lines are ordinary four steel core aluminum stranded wires, without any special features, not one wire made of steel and three wires 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 urban areas and distribution systems with high requirements for power supply reliability in China. Although the price is high, it is the development direction of distribution lines.
