Aluminum-clad steel core aluminum stranded wire is an effective material for power transmission. It is composed of aluminum-clad steel core and aluminum stranded wire, which has the advantages of high strength, low conductivity, low power consumption, corrosion resistance, etc., and is widely used in power grid construction and maintenance. This article will introduce the composition structure, advantages and application scenarios of aluminum-clad steel core aluminum strands.
Composition structure of 1. aluminum-clad steel core aluminum stranded wire
The aluminum-clad steel core aluminum stranded wire is composed of three parts: the central steel core, the outer aluminum-clad steel core and the outer aluminum stranded wire. Among them, the central steel core is responsible for bearing tension and maintaining the distance between the poles; the outer aluminum-clad steel core is a layer of aluminum-wrapped steel core, which can reduce the line impedance and improve the conductivity and strength; the outer aluminum stranded wire is a kind of A wire formed by twisting strands of thin aluminum wires is responsible for transmitting electric energy.
Advantages of 2. Aluminum Clad Steel Core Aluminum Strand
High strength: The steel core of the aluminum-clad steel-reinforced aluminum stranded wire can withstand greater tension, while the outer aluminum stranded wire has good toughness and ductility, can withstand greater deformation and stress, and ensure the safety of the line And stability.
Low conductivity resistance: The outer aluminum stranded wire of the steel core aluminum stranded wire is twisted by multiple strands of thin aluminum wire, which can reduce the resistance and energy consumption of the line and improve the efficiency of power transmission.
Corrosion resistance: The outer aluminum stranded wire of the steel core aluminum stranded wire has good corrosion resistance and can adapt to various harsh weather and environmental conditions.
Environmental protection and energy saving: Compared with traditional copper-core wires, the manufacturing and use of aluminum-clad steel-core aluminum stranded wires consume less energy, and recycling is more convenient, and more in line with environmental protection requirements.
Application Scenarios of 3. Aluminum Clad Steel Core Aluminum Strand
Aluminum-clad steel core aluminum stranded wire is widely used in power transmission and distribution network construction, especially for large-span, high-voltage transmission lines. Its main application scenarios include:
High-voltage transmission lines: The excellent performance of ACSR can meet the requirements of high-voltage transmission lines, such as power transmission lines with voltage levels above 220 kV. Its high strength and low conductivity characteristics can effectively ensure the safety of the lines. And transmission efficiency.
Urban distribution network: urban distribution network needs to adapt to the needs of urbanization construction, such as high-rise buildings and complex underground pipeline network. The lightweight and flexibility of aluminum-clad steel core aluminum stranded wire can better meet these requirements, and its good corrosion resistance can also ensure the long-term stable operation of the line.
Wind farm: Wind farm needs to transmit the electric energy generated by the generator to the substation for use in the power supply network. The high strength and low conductivity characteristics of aluminum-clad steel core aluminum stranded wire can reduce the transmission loss, and its flexibility can also adapt to the changeable and complex environment of wind farm.
Cable transmission: aluminum clad steel core aluminum stranded wire can also be used as the core of the cable, its high strength and flexibility can increase the tensile strength and durability of the cable, while its low conductivity characteristics can also improve the transmission efficiency of the cable.
In general, aluminum-clad steel core aluminum stranded wire has been widely used in high-voltage transmission lines. It has good economic and social benefits, can improve the stability and reliability of the power grid, and can also reduce environmental pressure, and has a good application prospect.
