thermal resistant aluminium alloy

 

traa-01
Our Thermal Resistant Aluminium Alloy is predominantly used for the manufacturing of Thermal Resistant Aluminium Alloy Conductors Steel Reinforced (TACSR) overhead transmission lines. TACSR are great for applications that require continuous operations above 150°C, which literally translates to a higher current capacity. A distinct characteristic of the Zirconium-doped aluminium alloy is its ability to maintain electrical and mechanical properties at elevated temperatures, thus making it an ideal cost-effective solution in refurbishing existing overhead lines with enhanced capacity.

A detailed specification of our Thermal Resistant Aluminium Alloy is as follows:
