Abstract

In order to compare with domestic underground distribution cables, the foreign cable which was manufactured in USA, 1982 and has been serviced in field for 13 years was characterized with several tests. Water trees, voids, and convolutions are not found in insulation. In hot oil test, insulation is very clean and there was no separation of insulation and conductor shield. The results of degree of crosslinking, FTIR, and DSC are also usual. Specially, the distribution of OIT is very good, which is different from that of domestic cables. The content of impurities is relatively small. This cables was manufactured with good state and no extraordinary degradation is found.
