Porcelain Shackle Insulator

Porcelain shackle insulators are designed to provide reliable insulation and support in high voltage applications. These insulators feature a disk-shaped design, typically with multiple stacked ceramic disks separated by metal or polymer spacers. Ceramic disk insulators offer excellent electrical insulation properties, high mechanical strength, and resistance to environmental factors such as moisture, pollution, and UV radiation.
