Basic research into the long duration behavior of insulating materials in SF6: Insulated transmission lines.
Abstract
The influence of increased power frequency voltages, to some extent combined with increased temperature of vibration, on the life time of insulators were studied in pressurized SF6. Full size insulators made of several material combinations are investigated; this provides data for advanced designs of SF6-insulated substations and bus connections. The test setups are mainly positioned in a 1.8 mV outdoor testing field. The research program and results from long duration tests (up to 12,000 h) are reported.
