Suspension disc insulators is generally made of insulating parts (such as porcelain parts, glass parts) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued or mechanically clamped. Disc suspension Insulator is widely used in power systems. They generally belong to external insulation and work under atmospheric conditions.
