High Temperature Thermal Resistant Alloy Conductor
GTACSR/GZTACSR has a unique construction featuring a small GAP between the steel core and (super) thermalresistant aluminium alloy layer. The combination of the super) thermal resistant aluminium alloy and the “Gap construction” offers excellent sag and current-carrying characteristics. With this advantage, GTACSR/GZTACSR is useful to up-rate an existing transmission line by simply replacing the existing Conductor to GTACSR/GZTACSR.
Aluminium-Zirconium wires (Type-AT3 or AT-1), concentrically stranded over a steel core maintaining gap between the Steel core and first Aluminium Layer.
At a temperature of 20°C (68°F), the density of hard-drawn aluminium has been taken as 2.703 g/cm3 (168.74 lb/cf) and for steel wire 7.8 g/cm3 (485.69 lb/cf).
