What is composite insulator? Composite insulator is also called polymeric insulator. It is developed after toughen glass insulator and ceramic insulators, whose main insulation structure is consist of a fiber glass core (rod) and silicon housing and sheds. One both side, 2 metallic fittings are installed on each side with crimping technics. These 2 metal […]
Polymer insulators are also called composite insulators.They are made of fiber glass core with silicon rubber sheath,and metal fittings on both ends are crimped. The polymeric insulators has better performance in hydrophobicity and electrical aspects compared with porcelain insulators.On the other hand,it is lighter in weight which are more convinient for transportation.
