2. Better electrical performance: oxygen-free copper surface + high
quality carbon steel cores® much lower resistivity than steel, galvanized steel and other
3. High copper layer adhesion: copper layer and steel surface are
molecularly bonding ® no destruction at the time of stranding
4. Price is much lower in comparison with pure copper wire.
1, copper layer average thickness (conventional) ≥ 0.25mm;
2, tensile strength ≥ 600N/mm 2
3, flatness error ≤ 1mm
4, copper layer plasticity: grounding rods bent 30 º, the angle
with no cracks.
