2. Description

The AACSR-LOS-REG-GCN is a high-performance low-loss all aluminum alloy conductor steel reinforced, specially developed for renewable energy grid connection scenarios. It integrates five core advantages: ultra-low transmission loss, high electrical conductivity, stable impedance matching, strong adaptability to fluctuating power output, and durable performance in outdoor renewable energy environments.

The product adopts a low-loss optimized structure: the aluminum alloy strands are made of high-purity Al-Mg-Si alloy with special annealing treatment, improving electrical conductivity to ≥60% IACS and reducing transmission loss by 18% compared with conventional AACSR conductors. The steel core uses high-tensile galvanized steel wire with a scientifically designed cross-sectional ratio, ensuring sufficient mechanical strength while minimizing impedance. The concentric stranding design optimizes the conductor's electromagnetic performance, reducing harmonic interference and improving grid connection stability for fluctuating renewable energy output.

Compared with traditional conductors, this product significantly reduces clean energy waste during grid connection, helping renewable energy projects improve economic benefits and meet carbon reduction goals. It operates stably in the temperature range of -40ºC to 100ºC, adapting to harsh outdoor environments such as photovoltaic deserts, wind farm plateaus and coastal areas. The anti-oxidation and corrosion-resistant coating on aluminum strands enhances durability, reducing maintenance frequency in long-term outdoor operation. As an ideal low-loss solution for renewable energy grid connection, it bridges the gap between clean energy generation and grid integration, maximizing the utilization of green power.
