Characteristics of glass insulators
Small size, light weight, zero-value self-breaking, and easy detection; high mechanical strength; good arc resistance; good self-cleaning performance and not easy to age. In addition, the spraying material has the advantages of strong hydrophobicity, long-term resistance to pollution, low leakage current on the surface, and maintenance-free during operation; it is widely used in various circuits at home and abroad.Item | Spacing(mm) | Diameter(mm) | Creepage Distance(mm) |
