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
