Application of ACAR Conductors in Transmission and Distribution Lines
Release time: 2025-09-25
In modern power engineering construction, conductor selection is directly related to line safety and economic efficiency. During the design phase of a transmission and distribution project, after comparing various bare conductor materials, ACAR (aluminum-clad aluminum alloy reinforced conductor) was ultimately selected, achieving excellent results. Why Choose ACAR Conductor? ACAR conductors utilize an aluminum alloy core with a 1350-H19 aluminum outer layer, offering excellent mechanical and electrical properties. Compared to common ACSR conductors, ACAR offers higher tensile strength and current-carrying capacity at the same weight. This is particularly important for long-span, high-tension transmission lines. The project team primarily considered the following points during their evaluation: Mechanical Strength: ACAR's aluminum alloy core significantly improves overall tensile strength, meeting the requirements of high-tension lines. Current Capacity: At the same weight, ACAR offers higher current-carrying capacity than ACSR, reducing energy loss. Flexible Structural Design: The aluminum alloy core can be customized to meet different tension requirements, enhancing adaptability. Economic Benefits: While maintaining strength and current capacity, the line weight is reduced, lowering construction costs. Project Application Parameters The ACAR conductor model used in this project is 1600MCM. Its main parameters are as follows: Implementation Standard: ASTM B524 Conductor Diameter: 37.05 mm Cross-sectional Area: 811 mm² Weight: 2230 kg/km (1974 kg/km aluminum, 256 kg/km aluminum alloy) Construction: 54 aluminum wires (4.11 mm diameter) + 7 aluminum alloy wires (4.11 mm diameter) Rated Tensile Strength: 13,500 daN The conductor is supplied in reels and can be customized to length, facilitating transportation and installation. Application Results After adopting the ACAR conductor in this project: The overall strength of the line was improved, meeting the mechanical requirements of the long-span section. Power transmission efficiency was improved, reducing line losses during operation. Construction became more convenient, reducing labor and time costs during installation. Ultimately, the project not only ensured the stability and reliability of power supply, but also achieved a good balance between economy and technology.
