| Research Abstract |
The Polymer nano-composite was prepared by mixed addition of azobenzoic compound and Al_2O_3 nano-particle into LDPE to improve the electrical treeing resistance under ac voltage application. The experimental results showed that tree initiation voltage was increased by the mixed addition. The increasing ratio for the mixed addition depends on the kind of azobenzoic compound. The highest increasing ratio of 300% was obtained in the mixed addition of the compound and Al_2O_3 at the concentrations of 2.0 wt% and 3.0 wt%, respectively. The mixed addition was also effective for control of tree development especially in its incubation. The incubation period of the mixed addition was2000times longer than that for the specimen without any additive. However, the control effect depended significantly on the concentration of the compound and magnitude of applied voltage.
