Product Introduction

APPLICATION

Super Thermal Alloy Conductor Invar Reinforced (STACIR)

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.

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.
