Definitions
- the present invention relates to high tension electric insulators, and more particularly to the type supported from below.
- insulators of the type supported from below have in the past been provided with a bunched circumferential projection in front of the electrodes.
- the inner surface of m the projection has been coated with a layer of metal so as to obtain a favorable fleld distribution.
- I denotes an insulating body supported from below at'l. Thisbodyishollowasshownatl andthe inner wall of this hollow portion is coated with a layer of metal 3.
- the upper portion 4 of the insulator is cup-shaped and carries an annular projection or flange i so as to reach over the metallic layer 0.
- a stand-off insulator of the type supported from below which comprises an elongated body of insulation having upper and lower ends and having a hollow extending longitudinally from said lower end into the interior thereof; a flange of insulation having the general shape of a cup, formed integral with said elon ated body. extending circumferentially around said body in- 5 termediate said ends but wholly beyond said cavity. and curving towards said upper end to define an inner surface directed towards said upper end; a conducting metallic layer applied over the upper end of said body and extending continuously over said.
