Glass insulator


Glass insulators are critical equipment used in high-voltage AC and DC transmission lines, primarily functioning to insulate and suspend overhead conductors.

Glass insulator


The insulator is primarily composed of a glass component, a steel cap, steel feet, and an adhesive. The glass piece serves as the core, providing excellent insulation performance; the steel cap connects the conductors, transmitting tensile forces; the steel feet are securely anchored to the tower structure; and the adhesive ensures that all components are firmly bonded together.

Glass insulator


Widely used in high-voltage/high-power AC and DC transmission lines and substations, these devices provide essential functions such as insulating and supporting conductors, preventing pollution flashovers, and resisting arc formation—crucial for ensuring the safe and stable transmission of electricity.
