New Generation Conductors capable to work at High Temperature without any loss of Strength to carter High Ampacity requirement. Used as bare overhead transmission cable and as primary and secondary distribution cable. STACIR/AW offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity. And up-rate an existing transmission line by simply replacing the existing conductor without tower modification or reinforcement.
Super Thermal Resistant Aluminium Alloy Conductor Aluminium-Clad Invar Reinforced (STACIR/AW) consists of one or more layers of S-TAL Grade Aluminum-Zirconium wires AT3, concentrically stranded about a steel core. Steel Core wire for STACIR/AW is available with aluminum-clad Invar Wires (Ni-Fe Alloy) wires (AW). Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
