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 achieved

on a cable that had previously completed the requirements of IEC 62067 2006

Section 13 cable system test (reported separately). Thus it had completed a

sequence of load cycles as shown in Table 1. Furthermore the 230 kV XLPE Pre

Qualification Cable System has completed two sequences of impulse tests atelevated temperatures (10 positive / 10 negative).
