ACSR steel core aluminum twisted cable
Model
Steel-cored Aluminum Stranded Wire (ACSR)
Number of Cores
Single-core
Structure Description
Steel-cored Aluminum Stranded Wire (ACSR) is composed of two parts:
●Steel core: The center is made of high-strength steel wire, which provides mechanical strength, supports the conductor, and withstands tension.
●Aluminum strands: The outer layer consists of multiple aluminum wires stranded together, responsible for electrical conduction. The aluminum wires are stranded around the steel core in layers, typically 1 to 3 layers.
Application Range
1. Transmission Lines
High-voltage transmission: Used in high-voltage and extra-high-voltage transmission lines, especially for long distances and large spans.
Overhead lines: Commonly used in overhead transmission lines due to its high mechanical strength, capable of withstanding external forces such as wind and ice.
2. Substations
Busbars: Used as busbars in substations to transmit large currents.
3. Electrified Railways
Overhead contact systems: Used for the overhead contact systems in electrified railways to supply power.
4. Distribution Networks
Medium and low-voltage distribution: Suitable for medium and low-voltage distribution lines where higher mechanical strength is required.
5. Special Environments
Coastal areas: ACSR treated with corrosion protection is suitable for high-corrosion environments.
Mountainous and river-crossing areas: Suitable for complex terrain and large-span areas.
6. Temporary Power Supply
Emergency power: Used for temporary or emergency power supply lines, easy to set up and dismantle quickly.
7. Other Applications
Communication lines: Sometimes used as support conductors in communication lines.
Wind power generation: Used for transmission lines in wind farms.
Introduction Steel-cored Aluminum Stranded Wire (ACSR) is a conductor composed of a high-strength steel core and an outer layer of aluminum strands, combining high mechanical strength with excellent electrical conductivity, widely used in high-voltage transmission and overhead lines.
Advantages
●High strength: The steel core provides high tensile strength, suitable for large spans and high-tension environments.
●Good electrical conductivity: The outer aluminum strands have good electrical conductivity, suitable for power transmission.
●Lightweight: The low density of aluminum makes the overall weight lighter, facilitating transportation and installation.
●Cost-effective: Combining the advantages of steel and aluminum, it offers high cost-effectiveness.
●Corrosion resistance: It can be treated with corrosion protection to extend its service life and is suitable for harsh environments.
●Flexibility: The stranded structure provides a certain degree of flexibility, making it easy to install.
●Wide application: Suitable for various applications such as high-voltage transmission, overhead lines, and substations.
Specifications
Common models include JL/G1A, JL/G1B, JL/G2A, JL/G2B, JL/G3A, etc., with a general range of 16 to 1250 mm².
Cost and Materials
1. Material Costs
Aluminum strands: As the main conductive material, aluminum strands account for a significant portion of the cost. The price of aluminum is highly influenced by international market fluctuations.
Steel core: The steel core provides mechanical strength. It is usually made of high-strength steel wire, with relatively lower costs but crucial for overall performance.
2. Production Costs
Stranding process: The aluminum strands and steel core are processed into conductors through a stranding process, involving equipment, labor, and energy consumption.
Corrosion protection: Some ACSR requires corrosion protection to extend its service life, adding to the cost.
History
The history of Steel-cored Aluminum Stranded Wire (ACSR) dates back to the early 20th century. In 1907, engineers Edwin W. Rice and William D. Coolidge from General Electric (GE) in the United States, aiming to address the insufficient mechanical strength of pure aluminum wire, first proposed the design of incorporating a steel core into aluminum stranded wire, combining the electrical conductivity of aluminum with the tensile strength of steel. After the 1920s, with the growing demand for high-voltage transmission, ACSR quickly became the mainstream material for overhead transmission lines due to its lightweight, high strength, and cost-effectiveness. The global expansion of power grids after World War II further popularized its use and led to the development of various specifications and corrosion-resistant technologies to adapt to different environments (such as coastal and mountainous areas). China began to introduce and establish related standards (such as GB/T 1179) in the 1950s, gradually achieving domestic production. Today, ACSR remains one of the core materials for power transmission.
Manufacturing Process
The core manufacturing process is "steel core forming + aluminum strand layer stranding," balancing electrical conductivity and mechanical strength through precise stranding and corrosion protection to ultimately form a composite conductor suitable for high-voltage transmission.
Packaging
Usually, it is packed in rolls, with the number of meters per roll specified by the customer, and wrapped in plastic film or woven bags
Shaft packaging can also be used as needed.
