The composite post insulator is used for supporting bus-bar. Comparing with ceramic insulator, the composite insulator
has the following characteristics:
1. The composite post insulator has good hydrophobicity and anti-aging ability, anti-tracking and anti-erosion;
2. Composite post insulator has compact size, lighter weight , The weight of composite post insulator is only 1/7~1/10 of the weight of ceramic support, easy installation and transportation;
3. Composite post insulator has higher bending load, anti-puncture, anti-shock and anti-breakage, composite insulator may avoid the mechanical damage accident caused by ceramic insulator fail in damaged joint structure due to great change of temperature.
4. For the composite post insulator
, installation dimensions of top and bottom comply with the ceramic ones and easy to be exchanged.
