Description

Double-group adjustable insulator

Technical Field

The invention relates to the technical field of insulators, in particular to a double-group adjustable insulator.

Background

The insulator is a special insulating control and can play an important role in an overhead transmission line. The insulator is mounted on conductors of different potentials or between the conductor and a grounded member, and is capable of withstanding the action of voltage and mechanical stress. Insulators are various in types and shapes. Although the structures and the shapes of different types of insulators are greatly different, the insulators are composed of two parts, namely an insulating part and a connecting hardware fitting.

In order to make the insulator safer and more stable in practical use, a double-group insulator is usually connected with a fixed base and then connected with an electric line. However, the distance between the two insulators cannot be adjusted by the existing double-group insulator, when the installation space is limited, the installation is troublesome, and different fixing bases need to be replaced.

The base of the existing double-group insulator is directly fixed through bolts and the like, when an electric line is blown by wind and swings, the base of the double-group insulator becomes loose, so that a worker needs to check the base regularly, and the base of the existing double-group insulator cannot be further adjusted and tightened after being connected with the electric line, so that the insulator and the electric line are loosened to a certain extent.
