Electric porcelain bottles, typically composed of insulating components (such as porcelain) and metallic fittings (such as steel feet, 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. Overhead transmission lines, generator stations, transformer stations, and external conductors of various electrical equipment all require insulators for support, ensuring they remain insulated from the ground (or grounding objects) or other conductors with differing potential differences.
