Thermal Performance of Splices and Terminals in Pipe-Type Cable Systems

A 230kV pipe-type cable test circuit was installed in the Miami substation in the Florida Power & Light Company system. From actual test data collected, computer models were developed to allow the determination of the thermal characteristics and the ampacity of the potheads and splices on pipe-type cable systems. Field data collected from operating pipe cables in the Florida Power & Light system have validated the accuracy of these computer models developed from the test circuit parameters according to a set of simple guide lines.
