InstallationInstallation method of GTACSR/GZTACSR is basically the same as conventional ACSR. Only at the time of sagging, a special sagging method is required to apply all the tension to the steel core. JPS can dispatch a skilled supervisor for assistance in the installation work.

Principal behind small sagAt the time of sagging, all tension is applied to the steel core by a special stringing method. As a result, the thermal expansion characteristics of GTACSR/GZTACSR become that of steel core. The thermal expansion coefficient of steel core is 11.5X10-6(/C).and it is approximately half of normal ACSR (around 20X10-6(/C)).GTACSR/GZTACSR has better thermal expansion characteristics than conventional ACSR.So GTACSR/GZTACSR can maintain small sag in high temperature condition.

(Super) Thermal resistant aluminum alloy [TAI, ZTAI]Thermal-resistant aluminum alloy (TAI) and Super thermal-resistant aluminum alloy (ZTAI) improve its thermal-resistant characteristics by adding zirconium. ZTAI and TAI can keep its tensile strength in high temperature condition.TAI can withstand up to 150C and can carry 1.6 times current of Hard drawn aluminum (1350).ZTAI can withstand up to 210C and can carry 2.0 times current of Hard drawn aluminum (1350).Both TAI and ZTAI maintain nearly the same mechanical and electrical characteristics as Hard drawn aluminum (1350).

The size of dead-end clamp for GTACSR/GZTACSR is

slightly larger than conventional ACSR allowing it to

carry large current.

Other accessories are same as conventional ACSR*1.

In case of replacing an existing transmission line,

only compression type dead-end clamp should

be changed.

Other accessories can be re-used.

*1 In case suspension tower continues more than six spans, special semi-strain assembly is required.

DesignGTACSR/GZTACSR can be designed to have the same mechanical characteristics as existing ACSR. Design examples are shown below.
