Aluminum Conductor Steel Reinforced (ACSR) conductors are high-capacity, high-strength stranded conductors used extensively in overhead power transmission and distribution networks. In accordance with GOST 839-80, a Russian national standard, these conductors are engineered to deliver excellent mechanical strength, electrical performance, and reliability across long spans.
Key Features
High Strength-to-Weight Ratio: Ideal for long span and high-tension lines
Corrosion Resistance: Galvanized steel and aluminum offer long service life in harsh environments
Excellent Conductivity: Suitable for medium to high voltage transmission
Durability: Withstands mechanical stress, wind, and ice loading
Versatile Design: Available in multiple steel-aluminum ratios to meet different strength and conductivity needs
Applications
Overhead power transmission and distribution lines
Long-span rural electrification
Messenger wires for supporting other conductors
Cross-country or high-tension transmission corridors
Construction
ACSR conductors are composed of a central core of galvanized steel wires surrounded concentrically by one or more layers of aluminum wires. The steel core provides mechanical support, while the outer aluminum strands ensure excellent conductivity and reduced overall weight.
Steel Core: Provides high tensile strength for longer span applications
Aluminum Strands: Ensure high conductivity and corrosion resistance
Stranded Construction: Improves flexibility and ease of installation

Standard Compliance
The product is manufactured in accordance with the GOST 839-80 standard, which outlines:
Conductor Types: Covers a range of ACSR types with varying steel core strengths and aluminum configurations
Material Requirements: Specifies tensile strength, elongation, and electrical conductivity of steel and aluminum components
Dimensions and Tolerances: Sets precise dimensional limits for conductor diameter, layer arrangement, and wire gauge
Testing Procedures: Includes mechanical and electrical test protocols to ensure product reliability
International Equivalents:
While GOST 839-80 is a Russian standard, ACSR conductors are also available per ASTM B232, IEC 61089, and BS 215 Part 2.
Typical Designations under GOST 839-80
АС (ACSR in Cyrillic): Standard ACSR conductor designation
Examples: АС 70/11, АС 95/16, АС 120/19 – where the first number indicates aluminum area (mm²) and the second number indicates steel core area (mm²)
