　　Advantages of steel cored aluminum stranded wire:

　　 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 across geographical conditions such as rivers and valleys. It has good electrical 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.

　　The main applications of steel cored aluminum stranded wire are:

　　 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.

　　Steel cored aluminum stranded wire refers to the wire core of this cable being a steel wire core, which means that this wire is an aluminum wire with steel wire cores twisted together in the middle, called steel cored aluminum stranded wire; It is generally used in long-distance or longer distance transmission lines, and its characteristics are lower cost and lighter weight compared to copper core wires of the same specifications, with good tensile strength.

　　 The advantage of steel cored aluminum stranded wire is that it has a simple composition, but it has powerful functions and can be used on high voltage electrical frames to ensure the normal operation of voltage output. Some places have unique geographical conditions, such as stranded wires on long rivers and high mountains that can maintain a large span without breaking. The emergence of stranded wires reduces the difficulty of installing high-voltage electrical racks. If there is strong wind, there is no need to worry about them being pulled, and they can be used for a longer time in harsh environments, ensuring that maintenance and replacement are not required for a long time. The production cost of twisted wire is relatively low, which can save a significant portion of installation costs. Another important advantage is that it can carry large voltage and current loads. If high-intensity current output is required, the stranded wires can be concentrated together to increase the propagation force and speed, helping to output electricity in situations with high electricity consumption.

　　Acceptance rules and testing methods

　　 Acceptance rules and testing methods for finished stranded wires

　　 The packaging and labeling of finished stranded wires should comply with GB1179-83

　　 The single-layer or multi-layer process stranded wire of steel core aluminum stranded wire is a reinforced conductor outside the galvanized steel core wire, which plays an important role in the power and transmission line industry. Below is a brief introduction to the advantages and applications of steel core aluminum stranded wire.

　　packaging

　　 During normal loading, unloading, transportation, and storage, wires should be properly packaged to prevent damage.

　　The wires should be delivered in reels, with the distance between the outermost layer and the edge of the cable reel side panel not less than 30 mm, and properly packaged. The two wires connected together should have at least half of the single wire cut at a distance of not less than 15 cm from the connection point, and the fracture should be tightly tied.

　　 The delivery tray shall comply with the provisions of JB/T8137-2013 (all parts), and may also be agreed upon by the supply and demand parties through mutual agreement. Short section wires are allowed to be delivered in loops, and each loop should be tied at least three times and properly packaged.

　　 Steel cored aluminum stranded wire specifications 10/2~1440/100 comply with the GB/T1179-2017 standard.
