Sequence of Load Cycles Applied to the 230kV XLPE Pre Qualification Cable System
It is particularly noteworthy that the compliance with AEIC CS9-06 was achievedon a cable that had previously completed the requirements of IEC 62067 2006Section 13 cable system test (reported separately). Thus it had completed asequence of load cycles as shown in Table 1. Furthermore the 230 kV XLPE PreQualification Cable System has completed two sequences of impulse tests atelevated temperatures (10 positive / 10 negative).
