Power porcelain bottles are typically assembled using adhesive bonding or mechanical clamping of insulating components (such as porcelain parts) and metallic accessories (such as steel feet, iron caps, flanges, etc.). Insulators are widely used in power systems, generally serving as external insulation and operating under atmospheric conditions. Overhead transmission lines, generator plants, transformer stations, and the external live conductors of various electrical equipment all require insulators for support, ensuring they remain insulated from the ground (or grounding materials) or other conductors with differing potential differences.
