Product Description

1. Applications

• Overhead power lines in old urban districts and dense commercial blocks, adapting to narrow power corridors between buildings and existing pipelines.
• Power grid renovation projects in historical districts, where space for corridor expansion is limited and compact is required to protect cultural relics.
• Transmission lines in urban residential areas with small building spacing, reducing the risk of conductor contact with buildings and improving safety.
• Power supply lines in industrial parks with dense pipelines and cables, optimizing space utilization in narrow overhead and underground corridors.
• Grid connection lines for urban distributed energy systems, fitting into limited space between rooftop photovoltaic equipment and building facades.
• Auxiliary power lines for urban infrastructure such as subways, bridges and tunnels, where installation space is restricted by structural design.
• Renovation lines for aging urban power grids, replacing conventional conductors to increase corridor capacity without expanding the space footprint.
• Power lines in urban green belts and scenic areas, using compact structure to reduce visual impact and coordinate with landscape design.

2. Description

The AACSR-CMP-NCR-SPC is a high-performance compact all aluminum alloy conductor steel reinforced, specially developed for narrow power corridor scenarios. It integrates five core advantages: ultra-compact structure with small outer diameter, excellent space-saving performance, reliable current-carrying capacity, easy installation in limited space, and stable operation in complex urban environments.

The product adopts an advanced compact stranding design: the aluminum alloy strands are arranged in a dense concentric structure with optimized pitch, reducing the outer diameter by 15% 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 mechanical strength while maximizing space utilization. The compact structure not only reduces the required installation width of power corridors but also improves the insulation clearance margin in narrow spaces, reducing safety risks.

Compared with traditional conductors, this product effectively solves the problem of insufficient space in narrow power corridors, avoiding costly corridor expansion and demolition work in urban areas. Its small outer diameter simplifies installation in dense building areas, reducing the need for large-scale hoisting equipment and minimizing disturbance to residents and traffic. It operates stably in the temperature range of -40ºC to 90ºC, adapting to urban thermal island effects, seasonal temperature fluctuations and mild industrial pollution. With high electrical conductivity (≥58% IACS), it ensures low transmission loss, meeting the energy-saving requirements of urban smart grids. As an ideal compact solution for narrow power corridors, it provides efficient and space-saving power support for urban power grid renovation and expansion.
