Product Description

Product Introduction

It is composed of an iron cap, steel feet and glass parts. The iron cap is glued to the top of the glass part, and there is an inner hole in the middle of the glass part. The steel feet are glued to the inner hole. The glass part features a double-umbrella structure with an upper umbrella and a lower umbrella. The upper surface of the upper umbrella forms a certain Angle with the horizontal plane, while the lower umbrella has an arc structure. This structure can increase the creepage distance.

Performance advantage

Good pollution resistance: The double umbrella structure can utilize natural wind and rain to clean the dirt deposits on the surface, preventing moisture from seeping into the effective creepage distance, thereby enhancing the pollution resistance insulation level and reducing the rate of pollution flashover accidents. It is suitable for transmission lines in polluted areas.
Easy to detect: It has the feature of self-destruction at zero value. Maintenance personnel can observe it on the ground or from a helicopter without having to climb poles to inspect each piece one by one, reducing the labor intensity.
High mechanical strength: The surface layer of glass insulators has high mechanical strength, is less prone to cracking, has a slow aging rate, and can operate stably for a long time.
