Abstract
A recent development in the design of the cap and pin of suspension insulators, to enable compression principles of stress distribution to be incorporated, has made possible an increase from 6,000 lb to 11,000 lb in load as determined by time-load tests covering a period of 2 years. Also, fatigue failure caused by vibration has been found to occur in the metal part before the porcelain is affected.
