Suspended insulators, typically composed of insulating components (such as porcelain, glass) and metal fittings (like steel feet, iron caps, flanges, etc.), are assembled using adhesive bonding or mechanical clips. Insulators are widely used in power systems, generally serving as external insulation, operating under atmospheric conditions. They are essential for supporting the live conductors on overhead transmission lines, generators, transformer stations, and various electrical equipment, ensuring they remain insulated from the ground (or grounding elements) and other conductors with different potential differences.
