Product Description

1. Applications

• Power transmission lines across high-altitude plateaus, alpine valleys and mountainous areas with elevations above 3000m.
• Grid-connected lines for high-altitude wind farms and photovoltaic power stations, adapting to low air pressure and strong wind environments.
• Main power grid lines in remote high-altitude residential areas and border posts, ensuring reliable power supply in extreme weather.
• Renovation and upgrading lines for aging high-altitude power grids, replacing conventional conductors to improve line safety and stability.
• Cross-river and cross-valley long-span transmission lines in high-altitude regions, reducing the number of towers and construction difficulty.
• Emergency backup power lines for high-altitude key infrastructure such as hydropower stations and communication base stations.

2. Description

The AACSR-HST-HAL-PWR is a high-performance high-strength all aluminum alloy conductor steel reinforced, specially designed for power transmission in harsh high-altitude environments. It integrates six core advantages: superior tensile strength, excellent low-temperature resistance, strong wind vibration fatigue resistance, high current-carrying capacity, UV radiation resistance and corrosion resistance in thin air environments.

 

The product adopts a reinforced structural design: the aluminum alloy strands are made of high-strength aluminum-zirconium alloy material, which improves the tensile strength by 30% compared with conventional AACSR conductors; the steel core uses high-carbon galvanized steel wire with anti-brittle treatment, which can resist the brittle fracture risk caused by ultra-low temperature in high-altitude areas; the overall stranding adopts an optimized pitch design, which effectively reduces wind-induced vibration and galloping phenomenon of conductors in strong wind environments.

 

In addition, the conductor surface is coated with a special anti-UV coating, which can resist the strong ultraviolet radiation in high-altitude areas and prevent the aging and cracking of the aluminum alloy strands. It can operate stably in the temperature range of -50ºC to 100ºC, adapting to the extreme temperature difference between day and night in high-altitude regions. With high electrical conductivity, it reduces transmission loss by 10% under the same load condition, improving the energy utilization efficiency of high-altitude power grids. As an ideal power transmission solution for high-altitude areas, it provides reliable and durable power support for the construction and operation of high-altitude power infrastructure.

Product Parameters

Parameter Category	Parameter Name	Technical Details	Buyer Selection Guidelines
Electrical Performance	Electrical Conductivity	≥ 58% IACS	High conductivity reduces transmission loss in long-distance high-altitude lines, improving energy efficiency and reducing operation costs.
	DC Resistivity (20ºC)	≤ 0.0310 Ω·mm²/m	Low resistivity ensures stable voltage output, avoiding voltage drop caused by long spans and low air pressure in high-altitude areas.
	Rated Current	600A-2200A (Depends on Cross-Section)	Match high-altitude load demand: 600-1200A for small wind farms and residential power supply; 1200-2200A for large photovoltaic power stations and main grid lines.
Mechanical & Structural Performance	Aluminum Alloy Strand Tensile Strength	≥ 320MPa	High-strength strands enhance the conductor's ability to withstand the tension of long spans and strong winds in high-altitude valleys.
	Steel Core Tensile Strength	≥ 1570MPa	Reinforced steel core prevents conductor breakage caused by ice and snow loads and extreme wind in alpine regions.
	Elongation at Break	≥ 12% (Overall Conductor)	Appropriate elongation improves the conductor's adaptability to terrain settlement and temperature changes in high-altitude areas.
	Nominal Cross-Section Range	240mm²-800mm²	240-400mm² for high-altitude residential areas and small power stations; 400-800mm² for large wind farms and cross-valley main transmission lines.
	Outer Diameter (Typical)	240mm²: ≈ 22.6mm; 400mm²: ≈ 29.0mm; 800mm²: ≈ 39.8mm (Tolerance: ± 0.3mm)	Optimized outer diameter reduces wind resistance and galloping risk, compatible with standard high-altitude power fittings (clamps, dampers).
	Weight Per Meter	240mm²: ≈ 0.670kg/m; 400mm²: ≈ 1.115kg/m; 800mm²: ≈ 2.230kg/m	Lightweight design reduces tower load and construction difficulty in remote high-altitude areas with limited transportation conditions.
Environmental Adaptability & Durability	Low-Temperature Resistance	No Brittle Fracture at -50ºC; Mechanical Properties Remain Stable	Suitable for alpine high-altitude areas with extremely low temperatures in winter, avoiding conductor damage caused by cold brittleness.
