Development of Composite Insulators for Overhead Lines

Composite insulators for a.c. overhead lines with a nominal voltage.The design requirements for composite insulators for 154-kV service are set forth below.Design Of Composite Insulators.Structure of Composite Insulators.Designing Composite Insulators.Of leakage current on composite insulators, 4th.The insulators have conventionally been made of ceramics or glass.Figure 1. Structure of composite insulator.Figure 1 shows the structure of a composite insulator.They have as yet, however, been infrequently used as suspension insulators.
