Abstract:
An organic composite insulator comprising:an organic material insulator tube having a hollow portion into which an inside electrode for easing an electric field is inserted; an insulator sheath, a length thereof being shorter than that of the organic material insulator tube, provided on the outer circumference of the organic material insulator tube and having a plurality of body portions and watershed portions alternatively and continuously formed; a first end conductive fitting member fixedly provided on a first end of outer circumference on which the insulator sheath is not provided and on a part of a first end of the insulator sheath the first end conductive fitting member being applied a voltage; and a second end conductive fitting member fixedly provided on a second end outer circumference on which the insulator sheath is not provided and on a part of a second end of the insulator sheath, the second end conductive fitting member being grounded; the insulator sheath being made of an organic polymer material and having a first insulator sheath, a second insulator sheath and a third insulator sheath continuously aligned from the first end conductive fitting member to the second end conductive fitting member and integrally formed as a unit, the second insulator sheath being positioned in a vicinity of a top tip of the inside electrode inserted into the hollow portion of the organic material insulator tube from the second end conductive member, and outer diameters of the respective body portion and watershed portion in the second insulator sheath being greater than outer diameters of the respective body portion and watershed portions in the first and third insulator sheath.
