Insulator body is the main structural component of bushings that provides electrical insulation and mechanical support in high-voltage equipment.
The insulator body is the core component of electrical bushings, designed to isolate conductive parts from grounded structures while maintaining structural integrity under electrical, thermal, and mechanical stresses. It prevents electrical discharge and ensures safe operation in transformers, switchgear, and other high-voltage apparatus by maintaining precise dielectric properties and creepage distances.

Porcelain offers superior mechanical strength and UV resistance but is brittle. Composite (silicone/epoxy) provides better pollution performance, lighter weight, and impact resistance but may have lower thermal stability.
Creepage distance = total surface path length between electrodes, calculated per IEC 60815 based on pollution severity (20-40 mm/kV). It prevents flashover under contaminated conditions.
No, cracked porcelain or epoxy bodies must be replaced immediately as dielectric integrity is compromised. Minor surface contamination can be cleaned per manufacturer guidelines.
