TACSR TACSR/AW Conductor Overview
TACSR (Thermal Resistant Aluminum Conductor Steel Reinforced) and TACSR/AW (Thermal Resistant Aluminum Conductor Steel Reinforced with Aluminum Clad Steel) are high-temperature aluminum conductors designed for overhead power transmission lines. With their heat-resistant aluminum alloy composition, these conductors provide low-sag performance, high conductivity, and enhanced mechanical strength, making them ideal for smart grid infrastructure and renewable energy projects.
TACSR and TACSR/AW conductors offer superior sag-tension control, high-strength aluminum conductor properties, and corrosion resistance, making them excellent alternatives to traditional ACSR and ACSS conductors for energy-efficient power transmission.
TACSR & TACSR/AW Conductors Applications
Overhead transmission line aluminum conductor
High-voltage power transmission networks
Renewable energy projects (wind & solar power integration)
Smart grid aluminum conductor solutions
Industrial and urban electrical distribution systems
TACSR TACSR/AW Conductor Technical Specifications

Why Choose TACSR & TACSR/AW Conductors?
✅ High-Temperature Performance:
The thermally resistant aluminum conductor steel reinforced design allows operation at high temperatures without reducing tensile strength.
✅ Enhanced Sag-Tension Control:
Low-sag aluminum conductor properties reduce line sag, improving power transmission efficiency.
✅ Energy-Efficient and Durable:
TACSR conductor for power transmission lines ensures stable performance in extreme environments.
✅ Superior Corrosion Resistance:
TACSR/AW aluminum conductor with aluminum-clad steel core enhances durability in coastal and industrial environments.
✅ Longer Service Life & Cost-Effective:
High-strength aluminum conductor design improves longevity, reducing maintenance costs.
