A Study on electrical Characteristics of XLPE by additives

첨가제에 의한 전력 cable용 XLPE의 전기적 특성에 관한 연구

Three kinds of treeing inhibitors are added to investigate the effect on electrical properties of XLPE. The treeing inhibitors are barbituric acid, 4- (4-Nitrophenylazo) resorcinol and 4- (4-Nitrophenylazo) naphthol. Added amount of each treeing inhibitors varied form 0phr to 2.0phr. In order to know the changes of electrical properties, break down strength, tan$\delta$, and $\varepsilon$$_{r}$ were measured. Experimental results showed that electrical properties of each sample was slightly changed by amount of additives.s.
