Power porcelain bottles are typically assembled using adhesive bonding or mechanical clamping of insulating components (such as porcelain parts) and metal 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. They are required to support the external live conductors of overhead transmission lines, generator and transformer station busbars, and various electrical equipment, ensuring insulation from the ground (or grounding objects) or other conductors with differing potential differences.
