Problems solved by technology

[0003] With the rapid development of the national economy and the increasing demand for electricity, the corridors of transmission and distribution lines have decreased, resulting in the continuous increase of double-circuit and multi-circuit power lines erected on the same pole; Type insulators, erecting double-circuit and multi-circuit power lines on the same pole must increase the height of the pole tower, which increases the cost of power transmission and distribution line engineering, and the use effect is poor

Abstract

The invention relates to a compound cross arm insulator that has low cost and good using effect. The compound cross arm insulator comprises an insulator body, wherein one end of the insulator body is fixedly connected with a connecting terminal. A lead fixing base is fixedly connected with the insulator body and comprises a line pressing base. A line pressing groove and a screw hole are opened on the upper surface of the line pressing base. A line pressing plate is designed above the line pressing base. A line pressing plate groove is formed on the lower surface of the line pressing plate and the line pressing plate is further provided with a fixed hole. The line pressing plate groove corresponds to the line pressing groove, the fixed hole corresponds to the screw hole, and the line pressing plate and the line pressing base are fixed through a fixed bolt. A lead hanging lug is designed on the lower surface of the line pressing base.

Description

[0001] technical field [0002] The invention relates to an insulator, in particular to a composite cross-arm insulator. Background technique [0003] With the rapid development of the national economy and the increasing demand for electricity, the corridors of transmission and distribution lines have decreased, resulting in the continuous increase of double-circuit and multi-circuit power lines erected on the same pole; Type insulators, erecting double-circuit and multi-circuit power lines on the same pole must increase the height of the pole tower, which increases the cost of power transmission and distribution line engineering, and the use effect is poor. Contents of the invention [0004] The purpose of the present invention is to provide a composite cross-arm insulator with low cost and good application effect. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: a composite cross-arm insulator, including an insul...
