ポリマー材料の撥水性と電気的特性の回復特性

抄録

To evaluate the long-term reliability of polymeric material used for electric power apparatus in the coastal area and to establish its insulation diagnosis technique, we evaluated recovery characteristics of hydrophobicity and electrical property of silicone rubber (SiR) by performing a salt fog aging test. As the result, the required times for recovery between the hydrophobicity and the electrical property are different. The time when the leakage current begins to be detectable might be a good index of the deterioration diagnosis.
