doi:10.11930/j.issn.1004-9649.2013.5.66.4

Abstract

Abstract: The faults of 6 kV(and above) XLPE cables occurring in the State Grid during 2009-2011 is analyzed in terms of failure rate, failure location and failure causes and the typical failure types and characteristics are summarized. It can be concluded that, the failure rate of power cables has been decreasing year by year in recent years; the failure mainly occur in the cable itself; and in addition to construction, the main insulation aging, improper installation technology and overload are the main cable failure causes. Proposals are put forward to improve running reliability of power cables.

Key words: XLPE cable, fault, cause analysis, status assessment
