STER-TACSRTM

Sterlite® Thermal-resistant Aluminium-alloy Conductor, Steel Reinforced (TACSR) conductors are high ampacity conductors, wherein the inner core is composed of galvanized steel and the outer layers are composed of thermal-resistant aluminium-alloy

 
Application
 
Thermal-resistant Aluminium-alloy Conductor

Sterlite® Thermal-resistant Aluminium-alloy Conductor

TACSR conductors are recommended for new lines for high power transfer requirements.

Benefits

New aluminium alloys having high thermal resistance can carry 50%-60% more current than ACSR of the same size, while maximum sag and maximum working tension remains almost the same as that of ACSR.
● Can carry 50%-60% more current than ACSR of the same size.
● Higher capacity new lines can be built to deal with future demands.
