OUTER COVERING RUBBER FOR POLYMER INSULATOR |
摘要 |
An object is to provide a technique for manufacturing an outer covering rubber having high-voltage electrical insulation characteristics and mechanical characteristics, which are required for a polymer insulator, by decreasing an amount of an additive conducive to improvement in high-voltage electrical insulation characteristics to less than conventional 3% by mass, without using special additional equipment such as ultrasonic agitation. Provided is an outer covering rubber for a polymer insulator, which is obtained by adding an additive conducive to improvement in high-voltage electrical insulation characteristics to a rubber composition, and the additive is a fine powder obtained by crushing a ceramic hydrate into a particle size of 100 nm or less, and the amount of the additive is 0.5 to 2.5% by mass in the entire raw materials of the outer covering rubber for a polymer insulator. |
