TACSR (Thermal Resistant Aluminum Conductor Steel Reinforced) features zirconium-alloyed aluminum wires, enabling continuous operation at 150°C and boosting current-carrying capacity by 50% compared to standard ACSR.
Retains nearly identical outer diameter and weight to conventional ACSR, allowing direct replacement on existing towers without extra structural reinforcement, cutting line upgrade costs drastically.
The high-strength steel core delivers excellent tensile performance for long-span installation, while the optimized alloy composition ensures stable electrical and mechanical properties under prolonged high temperatures.
Outstanding corrosion resistance adapts perfectly to coastal, humid, heavily polluted and severe cold regions, extending service life for 1kV-750kV overhead transmission lines.
Ideal for power grid capacity expansion in dense urban areas with limited transmission corridors, delivering higher power throughput without new land acquisition.
Application
High Temperature Thermal Resistant Alloy Conductor : Aluminum-Zirconium wires (Type-AT1 or AT3), concentrically stranded over a steel core having a small gap between the Steel core & thermal-resistant aluminum alloy layer. These combination offers best Mechanical as well as Electrical Characteristics.
Extra High Strength Galvanized Steel (EST); or aluminum-claded Extra High Strength Steel (AW). Additional corrosion protection is achieved as High Temperature Grease is applied in Between GAP of Conductor.
Construction
Aluminium-Zirconium wires (Type-AT3 or AT-1), concentrically stranded over a steel core maintaing gap between the Steel core and first Aluminium Layer.
Values based on following Specifications:
• Thermal-resistant aluminium alloy wires (Type-AT3 or AT1) for overhead line conductor as per IEC 62004
• Concentric lay stranded overhead electrical conductors IEC 61089, IEC 62420
• Zinc-coated steel wires for stranded conductors IEC 888, ASTM B957 & more
• Zinc–5% Aluminum-Mischmetal Alloy-Coated Steel Core Wire EN 50540, ASTM B802, ASTM B803 or ASTM B958.
• Aluminium Clad Steel Wires, IEC 61232, ASTM B415, EN 50540 & More
Features:
• These can operate upto 210°C with specified strength loss,
• Can carry 100~150% more current as that of ACSR of the same size.
• For uprating lines, no modifications or reinforcement is required to the existing towers
• Limiting the sag increase with the increase of the temperature by the thermal expansion coefficient above knee-point related to the steel core
