| Outline of Final Research Achievements |
In this study, LDPE nano-composite mixed with Al2O3 and 4-hydroxyazobenzene was designed to practically obtain extreme high reliability for high voltage electrical insulation. The thermal endurance test up to 15,000h was carried out to prove the effectiveness in the practical use.
The properties for the evaluation were changes in weight, volume resistance, UV absorbance ratio and tree inception voltage. The test results indicated that RTE (Relative Thermal Endurance) of properties of weight and volume resistivity were increased with about 20 comparing with the base material, and breeding out of hc_Ab from the material is scarcely detected during the test. All of these results suggested that the mixed nano-composite is useful for insulating material with the performance of high thermal endurance.
