The authors studied fundamental behaviors of carbon black(CB)-filled electrical conductive materials for high voltage power cables. The facts were found that the conductivity was proportional with the amount of CB, and was affected by the kind of CB and matrix polymers. Futhermore, the effect of molding conditions of these materials on electrical conductivity was investigated using LDPE, EVA and EEA as base polymers. Consequently, the longer molding period and higher molding temperature gave higher conductivity suggesting that well developed CB structure gave excellent conductivity. Unexpected electrical breakdown phenomenonwas observed in lower conductive specimens which contain ca. 20 phr of acetylene black. In the case of CB having rather small sur-face area, e.g., acetylene black, degree of CB structure was proportional with the amount of bound rubber. TEM observations on these materials was also performed.
