It has been decided that composite insulator with high mechanical ratings (high SML) will be largely
used in the first lOOOkV UHV AC demonstration project in China. Therefore high mechanical
petformance is required for composite insulator.
At present standards, composite insulator's long-term mechanical performance is tested by three
insulators to withstand 60% MAv for 96 h. It is based on different types of end fittings many years ago.
Test results on crimped composite insulators show that both deviation of mechanical failure load and
slope of creepage are much better than previous insulators. It means that the present test requirement is
no longer suitable for the purpose of selecting excellent crimped composite insulators for the very
important UHV line.
The time-load characteristics of crimped composite insulators from several manufactures with high
SML are tested. And then a new design principle of mechanical properties of composite insulator is
suggested, and a higher test requirement is also suggested at the same time.
