The effects of elevated temperatures on socketed terminations in service

The paper addresses the performance of socketed terminations to spiral strand and their filling media at elevated temperatures, so that their performance in fire or other high temperature conditions can be assessed. A substantial programme of tests that has focussed on the creep-temperature-time relationship in metal and resin filled sockets is reported. It is concluded that resin filled sockets are likely to fail within 60 hours if their core temperature is held at 160°C or above, while the critical temperature for alloy filled sockets is nearer 210°C.
