High Conductivity – Low electrical resistance minimizes power loss in PV fuse protection circuits.
Cold Headed Strength – Grain flow continuity provides superior mechanical strength compared to machined parts.
Accurate Diameters (14–22mm) – Precisely controlled outer diameters ensure secure fitment in standard PV fuse holders and combiner boxes.
Corrosion Resistance – Optional tin/silver plating protects against long-term outdoor exposure (UV, humidity, temperature cycling).
Cost-Effective Volume Production – Cold heading reduces material waste and unit cost for high-volume solar projects.
