SOLID INSULATOR AND METHOD OF MANUFACTURING THE SAME |
摘要 |
The present invention is directed to provide a high strength solid insulator, and a method of manufacturing the same. The solid insulator is made of cristobalite porcelain containing cristobalite crystals in an amount of less than 10%, in which internal strain in the direction of compression in a columnar insulator body is larger in the diametrically outer portion thereof than in the diametrically inner portion thereof, and the difference Y in internal strain between the outer peripheral portion and diametrically central portion of the insulator body is defined by Y ~ (1.76 x 10-6) X, wherein X (mm) represents the diameter of the insulator body. The method of manufacturing the solid insulator is characterized in that a sintered insulator body is quenched to increase the difference in internal strain between the inner and outer portions of the insulator body. 28
