KTACSR & KTACSR/AW Conductor

KTACSR & KTACSR/AW Conductor

• These can operate upto 150°C with specified strength loss,
• Can carry 50 % to 80 % more current as that of ACSR of the same size.
• For large-crossing sections with reduced wind load of the tower

Application

KTACSR & KTACSR/AW- The full name: HIGH STRENGTH – THERMAL RESISTANT ALUMINIUM ALLOY CONDUCTOR STEEL REINFORCED.

High Temperature Thermal Resistant Alloy Conductor : These are high ampacity conductors with inner core composed of Galvanized steel or Aluminum clad Steel & outer layer composed of high Strength – thermal resistant aluminium alloy with round or trapezoidal shaped.
Aluminium-Zirconium wires (Type-AT2), concentrically stranded over a steel core.

Specifications
