KTACSR — K-Thermal Resistant Aluminum Alloy Conductor Steel Reinforced

Product Description

Application

High Strength – Heat Resistant Aluminum Alloy Conductor Steel Reinforced (KTACSR & KTACSR/AW)

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.

Standard

Basic design to：

High Strength – Thermal resistant aluminium alloy wires (Type-AT2) for overhead line conductor as per IEC 62004
Concentric lay overhead electrical stranded conductors IEC 61089, IEC 62219 or ASTM B779
Zinc-coated steel wires for stranded conductors IEC 888, ASTM B957 & more
Aluminium Clad Steel Wires, IEC 61232, ASTM B415, EN 50540 & More

Construction

Aluminium-Zirconium wires (Type-AT2), concentrically stranded over a steel core.

Features:

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.
