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