Suspended insulators, typically composed of insulating components (such as porcelain or glass pieces) and metallic accessories (like steel legs, iron caps, flanges, etc.), are assembled using adhesive bonding or mechanical clamping. Insulators are widely used in power systems, generally serving as external insulation and operating under atmospheric conditions. They are essential for supporting the external live conductors of overhead transmission lines, power plants, substation busbars, and various electrical equipment, ensuring they remain insulated from the ground (or grounding objects) or other conductors with different potential differences.
