Composite Hollow Insulator　　

Up to now, hollow core composite insulators have been most typically used as a direct one-for-one replacement for porcelain.

“Hollow composite insulators have several distinct advantages over porcelain in terms of performance,”

　　1. Light- ideal for use in areas prone to seismic disturbances.

　　2. Hydrophobicity-they perform well under polluted service conditions.

　　3. Safety, free from exploding porcelain shell.

　　4. Shorter delivery time than porcelain
