Electric porcelain bottles are typically made by bonding insulating components (such as porcelain pieces) with metal accessories (like 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, generator stations, transformer stations, and external conductors of various electrical equipment all require insulators to support them and to insulate them from the ground (or grounding materials) or other conductors with different potential differences.
