Electric porcelain bottles are typically made by bonding insulating components (such as porcelain) with metal accessories (such as steel feet, 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. Overhead transmission lines, busbars in power plants and substation transformers, and external live conductors of various electrical equipment all require insulators for support, ensuring they are insulated from the ground (or grounding material) or other conductors with different potential differences.
