Abstract :
This paper reports on an on-going study into assessing the long term dc performance and reliability of moulded production joints used in submarine repeatered optic communication cable systems. Emphasis is being placed on using meaningful short term accelerated ageing tests, results of which can be extrapolated to service life and conditions. Electrical breakdown data from ramp and constant stress tests of production mouldings are presented along with thin film samples microtomed from various parts of mouldings. Bulk space charge measurements of aged samples are reported and their effect on failure data are discussed
