TACSR Thermal Resistant Aluminum Alloy Conductor Steel Reinforced
TACSR = Thermal-resistant Aluminum alloy Conductor Steel Reinforced， In Chinese, it is called heat-resistant steel core aluminum alloy stranded wire, which is an overhead wire that can operate at high temperatures for a long time and significantly increase the current carrying capacity by replacing the outer layer with heat-resistant aluminum zirconium alloy (TAL) on the basis of ordinary ACSR.

Applied to line capacity expansion and renovation; High density power transmission in urban/industrial areas; Long distance/large span lines; Coastal/Corrosive Environment
Applicable Standards
National standard: GB/T 1179
International: IEC 61089
American standard: ASTM B232
Japanese Standard: JEC 197
Common Specifications
Section: 50-800 mm ²
Structure: such as 24/3.5+7/2.6 (24 TAL+7 steel wires)
Steel ratio: about 15% -30% (by section)
Construction
- Core wire: Galvanized steel or aluminum clad steel (AW), providing tensile strength.
- Outer layer: heat-resistant aluminum zirconium alloy (TAL, Al Zr), replacing pure aluminum (1350) in ACSR.
- Twisting: Concentric layer twisting, steel core centered, heat-resistant aluminum alloy wire on the outer layer.
- Common writing for model: TACSR (galvanized steel core), TACSR/AW (aluminum clad steel core, more corrosion-resistant).
- *We can design and produce according to client's requirement.
