STACIR/AW,Hi-STACIR/AW SUPER THERMAL-RESISTANT ALUMINUM-ALLOY CONCUCTORS, ALUMINUM-CLAD INVAR REINFORCED

Used for overhead power transmission lines

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°C

Application

STACIR/AW, Hi-STACIR/AW is normally used to up-rate an existing transmission line by simply replacing the existing conductor without tower modification or reinforcement.

Super thermal-resistant aluminum alloy conductor,aluminum clad Invar reinforced is a high ampacity conductor with inner core composed of aluminum clad Invar/high tensile strength aluminum-clad Invar& outer layer composed of super thermal-resistant aluminium alloy with round.

Specifications

Double current carrying capacity of the same size ACSR
No limitation for application area : Heavy wind, snow & galloping area
Equivalent Sag-tension properties to conventional ACSR
No modification & reinforcement on existing tower
Easy installation with same method & equipments as ACSR’s
Low cost and short construction period
