Description

Technical Field

[0001] This utility model relates to the field of electrical technology, specifically to a sleeve shielding component with fixed support. Background Technology

[0002] In 0.6–35kV medium and low voltage American-style bushings, to facilitate accurate judgment of whether the installation is in place when installing with cable joints, the bushings are generally designed with positioning marks. During installation, the positioning marks are considered to be in place when they are completely covered by the cable joint. The positioning marks are generally yellow nylon circles, which are integrally molded with epoxy resin in the mold cavity during bushing molding. Because current bushing manufacturing technology generally uses vacuum pressure gel molding, the positioning marks are easily displaced by the molding pressure and the impact of epoxy resin in the mold cavity, thus failing to achieve the positioning effect.

[0003] Existing bushing shields have fixed support structures, which are mostly fixed installations and cannot be adjusted according to usage requirements. This limits the use of fixed support components for bushings. Therefore, a bushing shield with fixed support is proposed. Utility Model Content
