Aluminum Conductor Steel Reinforced (ACSR) conductors are among the most widely used types of overhead transmission lines in the power industry. Known for their strength and efficiency, these conductors are made with a steel core surrounded by layers of high-conductivity aluminum strands. The combination of aluminum’s light weight and steel’s high tensile strength makes ACSR ideal for long-distance power transmission.
HNBFpower, a trusted name in the electrical industry, provides high-quality ACSR conductors designed for superior performance and durability under various environmental conditions.
Basic Specifications of ACSR Conductors
ACSR conductors are manufactured in various configurations to meet different voltage and capacity requirements. Here are the main specifications that define their performance:
- Construction: Aluminum strands wrapped around a central steel core.
- Material: Hard-drawn aluminum (for conductivity) and galvanized steel (for strength).
- Stranding: Varies depending on the type, such as 6/1, 12/7, or 26/7 (indicating the ratio of aluminum to steel wires).
- Size Range: Available in a wide range of diameters and cross-sectional areas.
- Temperature Rating: Typically up to 75°C for standard designs.
- Corrosion Resistance: Steel core is galvanized to resist rust and environmental wear.
These technical specifications ensure the conductor can withstand mechanical stress, wind load, and environmental changes without compromising electrical efficiency.
Key Characteristics of ACSR Conductors
ACSR conductors are chosen for their combination of strength, conductivity, and reliability. Below are some of their main characteristics:
- High Tensile Strength:
 The steel core provides strong mechanical support, allowing the conductor to span long distances with fewer supporting towers.
- Excellent Conductivity:
 Aluminum’s high electrical conductivity ensures minimal power loss during transmission.
- Lightweight Design:
 The use of aluminum reduces overall weight, making installation and handling easier.
- Thermal Stability:
 ACSR conductors perform efficiently under high current and temperature conditions.
- Durability:
 The galvanized steel core helps resist corrosion, ensuring long operational life even in harsh environments.
- Low Sag Performance:
 The steel reinforcement helps maintain conductor shape and prevents sagging under load.
