Product Description

1. Applications

• Overhead power distribution lines in urban residential areas and dense building zones, adapting to limited tower load capacity and narrow construction space.
• Power grid renovation lines in old urban districts, replacing heavy conventional conductors to reduce tower reinforcement costs and construction disturbance.
• Overhead lines along urban main roads, ring roads and commercial blocks, fitting narrow power corridors between buildings and traffic facilities.
• Power supply lines for urban new districts and smart city construction, matching the lightweight and efficient requirements of modern urban grids.
• Auxiliary overhead lines for urban public facilities, such as schools, hospitals and subway stations, ensuring convenient construction with minimal public impact.
• Grid connection lines for urban distributed renewable energy (rooftop photovoltaic, small wind power), adapting to the compact layout of urban energy facilities.
• Temporary overhead power lines for urban infrastructure construction, benefiting from lightweight design for quick installation and disassembly.
• Overhead lines in urban green belts and scenic areas, reducing visual impact and tower footprint to coordinate with urban landscape.

2. Description

The AACSR-LWT-URB-OHP is a high-performance lightweight all aluminum alloy conductor steel reinforced, specially developed for urban overhead power grid scenarios. It integrates five core advantages: significant weight reduction, excellent mechanical strength-to-weight ratio, compact structure for narrow corridors, easy installation in dense urban areas, and stable performance in urban complex environments.

The product adopts a lightweight optimized structure: the aluminum alloy strands are made of high-strength Al-Zr alloy with refined grain technology, reducing the overall weight by 18% compared with conventional AACSR conductors under the same current-carrying capacity; the steel core uses high-tensile galvanized steel wire with a reasonable cross-sectional ratio, ensuring sufficient tensile strength while controlling weight. The compact concentric stranding design reduces the outer diameter by 10%, making it suitable for narrow urban power corridors and reducing wind resistance and visual interference.

Compared with heavy traditional conductors, this product significantly lowers tower load pressure, avoiding costly tower reinforcement during old urban grid renovation. Its lightweight feature simplifies transportation and installation, reducing the need for large-scale hoisting equipment and minimizing traffic disruption and noise pollution in dense urban areas. It operates stably in the temperature range of -40ºC to 90ºC, adapting to urban thermal island effects and seasonal temperature fluctuations. With high electrical conductivity (≥58% IACS), it ensures low transmission loss, meeting the energy-saving requirements of urban smart grids. As an ideal lightweight solution for urban overhead power grids, it balances efficiency, convenience and environmental adaptability for urban power construction.
