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°C

Standard

IEC, ASTM, LSC Standard, JCS 1405

•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

•Proved long-term reliability

Application

Hi-TACSR/AW is used for electric power transmission lines. River-crossing area, seaside district and over seas area, long span, mountain area etc.
