Product Description

1. Applications

• High-voltage (110kV-500kV) power transmission lines in coastal areas, including coastal city main power grids and inter-city coastal transmission networks.
• Long-span cross-sea, cross-island or cross-river transmission lines in coastal regions, adapting to complex marine terrain and large-span layout needs.
• Power transmission lines for offshore wind farms (from wind turbines to booster stations, booster stations to onshore grids), resisting marine salt spray and strong wind erosion.
• Power supply lines for coastal industrial parks, ports and coastal tourist resorts with high corrosion and strong wind risks.
• Renovation and upgrading projects of old coastal power grids, replacing traditional conductors with poor corrosion resistance to improve grid stability.
• Coastal high-altitude or coastal mountainous power transmission lines that need to withstand strong wind (≤30m/s) and light-heavy ice (≤25mm) loads.

2. Description
 

The AACSR-A3-SCX-CR-WRS-CAS is a high-performance overhead transmission conductor specially developed for harsh coastal environments. It adopts a concentric stranding structure with Al-Fe corrosion-resistant alloy core (A3 grade) and 37-strand ultra-high strength galvanized steel core (SCX grade), integrating the excellent corrosion resistance of Al-Fe alloy, the ultra-high tensile strength of multi-strand steel core and the reliable electrical conductivity of aluminum alloy.

Compared with conventional ACSR conductors, this product has significantly improved corrosion resistance-its Al-Fe alloy layer and galvanized steel core with aluminum coating form a double anti-corrosion barrier, which can effectively resist salt spray erosion, humidity and chemical corrosion in coastal 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 coastal cross-sea, cross-island scenarios.

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

Product Parameters

 

Parameter Category	Parameter Name	Technical Details	Buyer Selection Guidelines
Electrical Performance	Electrical Conductivity (Aluminum Alloy Layer)	≥55% IACS	Balances corrosion resistance and electrical conductivity, meeting the high-efficiency transmission needs of coastal high-voltage power grids without excessive power loss.
	DC Resistivity (20ºC)	≤0.0317 Ω·mm²/m	Low resistivity ensures stable voltage transmission in long-distance coastal lines (≥50km), avoiding excessive voltage drop for end users.
	Rated Current	800A - 2800A (Depends on Cross-Section)	Match with coastal load demand: 800-1500A for coastal city distribution lines; 1500-2800A for offshore wind farm main transmission lines and cross-sea trunk lines.
Mechanical & Structural Performance	Tensile Strength	≥60000N	Ultra-high tensile strength fully meets the load-bearing requirements of long-span (≥300m) cross-sea, cross-island lines, withstanding self-weight, wind and ice loads.
	Elongation at Break	Aluminum Alloy Layer: ≥15%; Overall Conductor: ≥8%	High elongation improves installation flexibility, adapting to the complex terrain of coastal construction; avoids strand breakage during hoisting and laying.
	Nominal Cross-Section Range	Aluminum Alloy Layer: 630mm² - 1200mm²; Steel Core Cross-Section: 120mm² - 200mm²; Overall Cross-Section: 750mm² - 1400mm²	630-800mm² for coastal city high-voltage distribution lines; 800-1200mm² for large-scale offshore wind farm transmission and cross-sea long-span trunk lines.
	Outer Diameter (Typical)	630mm²: ≈34.5mm; 800mm²: ≈39.2mm; 1200mm²: ≈46.2mm; Tolerance: ±0.3mm	Confirm compatibility with coastal overhead hardware (high-strength clamps, suspension insulators, anti-vibration dampers) before purchase; matches standard high-voltage coastal power fittings.
	Weight Per Meter	630mm²: ≈4.50kg/m; 800mm²: ≈5.85kg/m; 1200mm²: ≈8.10kg/m	The weight is reasonably controlled under the premise of ensuring strength and corrosion resistance; it is compatible with most coastal high-voltage tower structures without additional reinforcement.
Environmental Adaptability & Durability	Operating Environment	Humidity: ≤98%; Adapt to Coastal Salt-Spray Zones, Strong Wind Zones (≤30m/s), Light-Heavy Ice Zones (≤25mm), High-Altitude Coastal Areas (≤4500m)	Not recommended for ultra-heavy ice (≥30mm) zones; fully adapted to the harsh natural environment of coastal areas, no need for frequent maintenance.
	Corrosion Resistance Details	Al-Fe Alloy Layer: Natural Oxide Film; Steel Core: Hot-Dip Galvanizing (≥90μm) + Optional Zinc-Aluminum Coating; Pass 2000h Neutral Salt Spray Test	Standard model meets the corrosion resistance requirements of general coastal areas; for severe salt spray zones (e.g., offshore platforms), choose zinc-aluminum coated steel core models.
	Length Per Roll	630-800mm²: 500m/roll; 1200mm²: 300m/roll; Customizable Long-Length Rolls for Bulk Cross-Sea Projects	Long-length rolls (500m) reduce the number of joints in large-scale coastal projects, improving transmission stability; 300m/roll for small-scale maintenance and branch line construction.
	Anti-Wind Vibration Performance	Alternate Lay Direction + Uniform Stranding; Resist Wind Vibration Fatigue for Long-Term Operation	Suitable for coastal strong wind zones, effectively reducing the risk of conductor fatigue damage and broken strands caused by long-term wind vibration, ensuring long-term operation safety.
