Abstract
This disclosure is directed to an insulator for clamping and holding an electrical conductor above the ground for aerial power distribution and transmission. The insulator includes a body member, first jaw means integral with one end of the body member, slide means, second and third jaw means integral with the slide means and means for mounting the slide means in the end of the body member for longitudinal movement substantially normal to the first jaw means. It also includes bolt means for causing movement of the third jaw means towards a concave neck portion of the body member for gripping a conductor between the third jaw means and the body member. This disclosure is also directed to a method of stringing an electrical conductor on a plurality of insulators which are supported above the ground on a series of poles. The method utilizes a plurality of stringing devices each of which comprises two semi-tubular members having means for detachably securing them together to provide a circular passage between them. The conductor is pulled through a series of stringing devices which are held between the generally concave surfaces of the insulator bodies and generally concave surfaces of…
