Product Description

1. Applications

• High-voltage (110kV-500kV) long-span transmission lines in mountainous areas, including cross-valley, cross-mountain and inter-mountain power transmission networks.
• Power transmission lines for mountainous wind farms (from wind turbines to booster stations, booster stations to onshore main grids), adapting to complex mountainous terrain and strong wind conditions.
• Power supply lines for mountainous residential areas, mining areas and mountainous industrial parks that require long-span power transmission across rugged terrain.
• Renovation and upgrading projects of old mountainous power grids, replacing traditional conductors with insufficient strength to improve the stability and safety of long-span lines.
• High-altitude mountainous power transmission lines that need to withstand strong wind (≤35m/s), light-heavy ice (≤25mm) and low-temperature loads.
• Long-span power transmission lines in remote mountainous areas with difficult construction conditions, requiring high-strength and low-maintenance conductors.

2. Description
 

The AACSR-A2-SCX-HSS-WVR-MTS is a high-performance overhead transmission conductor specially developed for harsh mountainous long-span environments. It adopts a concentric stranding structure with Al-Zr ultra-high strength alloy core (A2 grade) and 37-strand ultra-high strength galvanized steel core (SCX grade), integrating the excellent tensile strength of Al-Zr alloy, the ultra-high load-bearing capacity of multi-strand steel core and the reliable electrical conductivity of aluminum alloy.

Compared with conventional ACSR conductors, this product has significantly improved mechanical strength-its Al-Zr alloy core and 37-strand high-strength steel core form a double load-bearing structure, which can effectively withstand the combined loads of self-weight, strong wind and ice in mountainous areas. The 37-strand steel core structure ensures ultra-high tensile strength, fully meeting the load-bearing requirements of long-span (≥300m) transmission lines in mountainous cross-valley, cross-mountain scenarios.

In addition, the alternate left-right lay direction of the stranding structure enhances the conductor's stability under strong mountain wind vibration, avoiding fatigue damage caused by long-term turbulent wind load in mountain valleys. It is an ideal core component for mountainous power grid construction and wind power projects, providing long-term, stable and reliable power transmission guarantee for mountainous areas with complex terrain and harsh wind conditions.

Product Parameters

 

Parameter Category	Parameter Name	Technical Details	Buyer Selection Guidelines
Electrical Performance	Electrical Conductivity (Aluminum Alloy Layer)	≥56% IACS	Balances high strength and electrical conductivity, meeting the high-efficiency transmission needs of mountainous high-voltage long-span power grids without excessive power loss.
	DC Resistivity (20ºC)	≤0.0312 Ω·mm²/m	Low resistivity ensures stable voltage transmission in long-distance mountainous lines (≥50km), avoiding excessive voltage drop for mountainous residential and industrial end users.
	Rated Current	850A - 2900A (Depends on Cross-Section)	Match with mountainous load demand: 850-1600A for mountainous residential and mining area distribution lines; 1600-2900A for mountainous wind farm main transmission lines and cross-valley trunk lines.
Mechanical & Structural Performance	Tensile Strength	≥62000N	Ultra-high tensile strength fully meets the load-bearing requirements of long-span (≥300m) cross-valley, cross-mountain lines, withstanding self-weight, strong wind, ice and other complex loads in mountainous areas.
	Elongation at Break	Aluminum Alloy Layer: ≥15%; Overall Conductor: ≥8%	High elongation improves installation flexibility, adapting to the complex terrain and difficult construction conditions of mountainous areas; avoids strand breakage during hoisting and laying.
	Nominal Cross-Section Range	Aluminum Alloy Layer: 630mm² - 1200mm²; Steel Core Cross-Section: 125mm² - 210mm²; Overall Cross-Section: 755mm² - 1410mm²	630-800mm² for mountainous residential and mining area high-voltage distribution lines; 800-1200mm² for large-scale mountainous wind farm transmission and cross-valley long-span trunk lines.
	Outer Diameter (Typical)	630mm²: ≈34.8mm; 800mm²: ≈39.5mm; 1200mm²: ≈46.5mm; Tolerance: ±0.3mm	Confirm compatibility with mountainous overhead hardware (high-strength clamps, suspension insulators, anti-vibration dampers) before purchase; matches standard high-voltage mountainous power fittings.
	Weight Per Meter	630mm²: ≈4.60kg/m; 800mm²: ≈5.95kg/m; 1200mm²: ≈8.25kg/m	The weight is reasonably controlled under the premise of ensuring ultra-high strength; it is compatible with most mountainous high-voltage tower structures without additional reinforcement, reducing construction costs.
Environmental Adaptability & Durability	Operating Environment	Humidity: ≤98%; Adapt to Mountainous Strong Wind Zones (≤35m/s), Light-Heavy Ice Zones (≤25mm), High-Altitude Mountainous Areas (≤5000m), Low-Temperature Zones (-50ºC to -20ºC)	Not recommended for ultra-heavy ice (≥30mm) zones; fully adapted to the harsh natural environment of mountainous areas, no need for frequent maintenance, suitable for remote mountainous areas with difficult maintenance.
	Anti-Corrosion Performance	Al-Zr Alloy Layer: Natural Oxide Film; Steel Core: Hot-Dip Galvanizing (≥90μm) + Optional Zinc-Aluminum Coating; Pass 1500h Neutral Salt Spray Test	Standard model meets the corrosion resistance requirements of general mountainous areas; for high-humidity mountainous areas (e.g., rainy mountain valleys), choose zinc-aluminum coated steel core models.
	Length Per Roll	630-800mm²: 500m/roll; 1200mm²: 300m/roll; Customizable Long-Length Rolls for Bulk Cross-Valley Projects	Long-length rolls (500m) reduce the number of joints in large-scale mountainous projects, improving transmission stability; 300m/roll for small-scale maintenance and branch line construction in mountainous areas.
	Anti-Wind Vibration Performance	Alternate Lay Direction + Uniform Stranding; Resist Wind Vibration Fatigue for Long-Term Operation; Adapt to Turbulent Wind in Mountain Valleys	Suitable for mountainous strong wind and turbulent wind zones, effectively reducing the risk of conductor fatigue damage and broken strands caused by long-term wind vibration, ensuring long-term operation safety of mountainous long-span lines.
