Product Description

Super Thermal Alloy Conductor Invar Reinforced (STACIR) conductor

Invar Conductor Manufacturer & Supplier from China

STACIR STACIR/AW Conductor Application

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.

STACIR Conductor Construction

Core Wire (INVAR) : Aluminum-clad INVAR Wire/High Tensile Strength Aluminum-clad INVAR Wire

Conductor (STAl) : Super Thermal Resistant Aluminum Alloy Wire used for continuous allowable temperature up to 210℃

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.

STACIR STACIR/AW Conductor Standard

IEC, ASTM, JCS 1405
