Product Technical Overview

GIS internal conductors carry continuous rated load and heavy short-circuit currents inside SF6 coaxial enclosures. Produced from high-conductivity extruded aluminum alloy tubes (conductivity > 55% IACS) and electrolytic T2 copper bars with thick hard silver plating on contact surfaces, minimizing contact resistance and Joule heating.
