Steel core aluminum alloy stranded wire manufacturer

Description :

　　In the design of overhead transmission lines, the sag of the conductor is related to the span of the crossing span. If the span of the crossing span is too large, it often leads to excessive sag of the conductor, insufficient safety distance to the crossing object or bottom surface, and cannot meet the requirements of the regulations. To solve the problem of insufficient safety distance between the conductor and the bottom or crossing object, it is usually achieved by raising the height of the crossing tower. However, blindly increasing the height of the tower not only leads to an increase in project cost, but also reduces the safety of the tower if it is too high. With the emergence of steel cored aluminum alloy stranded wire, it has been widely used in the design of large-span transmission lines due to its advantages in sag characteristics. Transmission line; Sag characteristics; Great leap forward; Steel cored aluminum alloy stranded wire

　　Steel cored aluminum alloy stranded wire (aluminum alloy stranded wire) is one of the main products in the wire and cable manufacturing industry, widely used in high-voltage or ultra high voltage transmission lines. Compared with steel core aluminum alloy stranded wire, the characteristic of steel core aluminum alloy stranded wire is that the comprehensive tensile breaking force of the wire is greatly improved, which increases the tension to weight ratio of the wire. Due to the characteristic of steel core aluminum alloy stranded wire (aluminum alloy stranded wire), in the design and construction of high-voltage or ultra high voltage transmission line projects, the span of supporting wire towers can be relaxed, the number of towers built can be reduced, land resources or tower height can be saved, and the amount of steel used in towers can be reduced, thereby reducing the construction cost of transmission line projects. Especially in transmission lines used in harsh environments such as wind and snow resistance, the superior performance of this product is further demonstrated. Due to its incomparable advantages, aluminum alloy wires have a unique advantage in long-distance, large-span, and ultra-high voltage transmission; In the transformation of rural power grids, it is an advanced and economical good product. It is an upgraded product of ordinary steel core aluminum stranded wire, as well as an energy-saving, material saving, and land saving product (saving transmission corridors).

　　Steel cored aluminum alloy stranded wire (aluminum alloy stranded wire) has been used for overhead lines since 1921. With the improvement of transmission and transformation technology and the development of transmission and transformation lines, aluminum alloy wires are increasingly demonstrating their superiority. They have been widely used internationally for 50 years and have been widely adopted in Western Europe, Northern Europe, the United States, Canada, Japan and other countries. Almost 90% of transmission lines in France use aluminum alloy wires, and more than 50% in Japan. The usage in Southeast Asian countries is increasing year by year.

　　Advantages of Steel cored Aluminum Alloy Stranded Wire

　　1.1 Strong tensile strength

　　Steel cored aluminum alloy stranded wire is a multi strand solid stranded wire composed of an outer layer of aluminum, magnesium, silicon alloy wire and an inner layer of steel wire. Strong tensile strength. Compared with ordinary steel cored aluminum stranded wire with the same aluminum cross-section, the comprehensive tensile strength of steel cored aluminum alloy stranded wire is 1.27 and 2.45 times that of ordinary steel cored aluminum stranded wire.

　　The wires used in overhead transmission lines are still mostly traditional steel cored aluminum stranded wires, and due to their relatively weak heat resistance, the transmission capacity of the lines is limited to a certain extent. High strength heat-resistant all aluminum alloy wires have outstanding advantages such as good heat resistance, high current carrying capacity, high tensile strength, light weight, good sag characteristics, and excellent corrosion resistance. They are used for the renovation of old lines, with outstanding capacity expansion effects and can save a lot of metal materials and infrastructure investment. They are especially suitable for lines that require high strength and large capacity, and can significantly improve transmission capacity and line safety. Based on successful international application experience and the excellent comprehensive performance exhibited by this type of wire, high-strength heat-resistant all aluminum alloy wire is expected to become a very important new type of overhead wire in China's large-span transmission lines.
