% 1ACS = 0.017241/p 20. The percentage of conductivity is expressed by the percentage of resistivity of 0.017421 mm2/m stipulated by IACS. Usually, when the resistivity of conductor is known at 20 C, it is calculated according to the above formula. The conductivity of oxygen-free copper can reach 102.0%, and its resistivity is p 20=0.017241/%IACS=0.017241/0.02=0.0169_.mm2/m, which meets the requirement of copper wire resistivity less than 0.017421_.mm2/m for cable industry enterprises.g9Z众邦电缆集团公司
