Application
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.
