Product Description

Thermal Resistant Aluminum Conductors Steel Reinforced with GAP (GzTASCR)

Gap-type ZT-aluminum conductor steel reinforced (GZTACSR) uses heat-resistant aluminum over a steel core.

GTACSR & GZTACSR Conductor 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.

GZTACSR 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

GZTACSR Conductor 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
