In this page, we'll introduce STACIR STACIR/TW Conductor and their advantages, applications, standards and frequently asked questions.
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.
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.
Hi-STACIR/AW, STACIR/AW is normally used to up-rate an existing transmission line by simply replacing the exisitng conductor without tower modification or reinforcement.
