Aluminum alloy stranded wire, aluminum stranded wire, and steel-core aluminum stranded wire are commonly used high-efficiency conductor materials in overhead transmission lines and are widely used in urban and rural power distribution, industrial power supply, and long-distance transmission projects.
Aluminum alloy stranded wire utilizes high-strength aluminum alloy conductors, balancing excellent conductivity and mechanical strength. It is lightweight and offers excellent tensile strength, making it suitable for long-span overhead lines and environments subject to strong winds, ice, and snow.
Aluminum stranded wire, primarily composed of pure aluminum conductors, offers excellent conductivity and heat dissipation. It is lightweight, easy to install, and economical, making it an ideal choice for urban power distribution and medium- and low-voltage overhead lines.
Aluminum steel-core stranded wire (ACSR) is a composite of a steel core and aluminum conductor. The steel core provides strong tensile strength, while the aluminum conductor ensures excellent conductivity. It can withstand long spans and heavy loads, making it suitable for high-voltage transmission lines and long spans.
Advantages:
Lightweight and high-strength: Aluminum alloy and aluminum stranded wire are lightweight, while steel-core aluminum stranded wire offers high strength, making it suitable for long-distance overhead installation. Excellent conductivity: Ensures efficient power transmission and reduces line losses.
High environmental resistance: Resists corrosion, wind and snow, stretching, and creep.
Easy to install: Flexible and easy to install, maintain, and replace.
High cost-effectiveness: Lower cost than all-copper conductors, making it suitable for large-scale power transmission and distribution projects.
