Title: Ceramic insulator for high voltage and its manufacture
Inventor: SATO MASAMI
IPC: H01B19/00
Filed: 1990-09-29
Abstract: PURPOSE:To manufacture a ceramic insulator for high voltage without lowering the sharp wave strength of the insulator with a standard size and also with the high sharp wave strength as the standard size even in the case that the head part is made small by making the bubbles existing in glaze to have spherical shape. CONSTITUTION:The bubbles existing in glaze 3 of a ceramic insulator 1 whose head 2 is coated with the glaze 3 are made spherical. In this case, the number of bubbles, which cause penetration damaging, in the glaze can be limited to 15/mm<2> by sintering the glaze-coated ceramic insulator 1 under reduced pressure in a range of suitable ceramic sintering temperature which is higher than the temperature under which the shapes of the bubbles contained in the enamel 3 become spherical. Consequently, without lowering the sharp wave strength with a standard size and also with the high sharp wave strength as the standard size insulator even in the case that the head part is made small, a ceramic insulator for high voltage is manufactured.
