Material Standard
Conductor Material
High quality oxygen-free copper rod selectedto produce the copper conductor,oxygen content is less than 20 ppm, conductivity is greaterthan 100% after annealing.
Optimal Non-proportional extension strength of semi-hard copper conductors (Rp0.2)
as below:C1 Rp0.2(>100~180)N/mm2Rp0.2 <200N/mm2 resistivity<1/58Q.mm?/m
C2 Rp0.2(>180~220)N/mm2Rp0.2>200N/mm2，resistivity<1/57.8 Ω.mm'/m
C3 Rp0.2(>220-260)N/mm2
High-quality electrician round aluminum rod was used to produce the aluminum conductor,conductivity is greater than 62% after annealing.
