Column porcelain insulator

Abstract

The invention provides a column porcelain insulator. When an aluminum steel conductor is fixed by utilizing the column porcelain insulator, the aluminum steel conductor is placed in a first groove first; the first groove is the same as a second groove; a distance from a first fixed hole to a central point of the second groove is the same as that from a first fixed rod to a central point of the first groove; a distance from a second fixed hole to the central point of the second groove is the same as that from a second fixed rod to the central point of the first groove; when a first bolt and a second bolt which are penetrated by nuts are screwed on the first fixed rod and the second fixed rod by penetrating through the first fixed hole and the second fixed hole, the first groove is aligned to the second groove, and the aluminum steel conductor is fixed by a groove formed by the first groove and the second groove, so that the abrasion to the aluminum steel conductor due to micro-vibration is reduced, the probability that the aluminum steel conductor is abraded is reduced, and a power failure rate is reduced; and the fixing mode is firmer than a binding mode, so that the aluminum steel conductor can be prevented from falling, and the personal safety is prevented from being endangered.

Description

technical field [0001] The present application relates to the technical field of electric power communication equipment, in particular to a pillar type porcelain insulator. Background technique [0002] Porcelain post insulators are post-style insulators made of electrical ceramics and are used to secure distribution lines. At present, the pillar-type porcelain insulator includes a porcelain piece, one end of which is provided with a groove matching the steel-reinforced aluminum conductor, and the other end is poured with a bolt. [0003] Porcelain insulators usually embed steel-cored aluminum conductors into the groove when fixing distribution lines, and use aluminum wires as binding wires to bind steel-cored aluminum conductors on the post-type porcelain insulators without binding steel cores. At the other end of the wire, bolts are passed through the fixing holes provided on the high-voltage transmission tower, and nuts are screwed on the bolts to fix the pillar porcelai...
