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
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.

Assumptions: Ampacity is calculated based on, 45°C (113°F) ambient temperature, 0.6 m/s wind velocity, 0.5 as coefficient of solar absorption, 0.6 as coefficient of emmisivity and 1200 wt/sqm coefficient for solar radiation, at sea level.
