STER-STACIRTM

Sterlite® Super Thermal Alloy Conductor Invar Reinforced (STACIR) conductor has outer layers composed of Super Thermal Aluminium (STAL) alloy wires that can operate up to 210°C (410°F). The inner core is composed of aluminium clad INVAR wires. INVAR is a metal alloy with 36% Ni in steel.

 
Application
 
Super Thermal Alloy Conductor Invar Reinforced

Sterlite® Super Thermal Alloy Conductor Invar Reinforced (STACIR)

STACIR/AW conductors are suited for re-conductoring applications. The capacity of existing transmission line can be enhanced by simply replacing the existing conductor without any modification to the tower.

Benefits

● Can carry 100% more current than that of ACSR of the same size, while maximum sag and maximum working tension remain the same as that of ACSR.

● No modification or reinforcement is required to existing towers for uprating transmission and distribution lines.

● Easy Installation, similar to conventional conductors.

● No Special Hardware/Accessories.

● Lower Thermal Expansion of Invar Core, Improve the Conductor Sag Performance.
