As the developed increasing of electric need, the power system have a large requirement of insulators, porcelain insulator can’t satisfied the system needs so silicon insulator are used to take the place of porcelain insulator.
Silicon insulators advantages are various, so silicon insulators are a huge advantage over porcelain insulators, following are some main silicon insulator advantages
Advantage:
Good mechanical properties, since silicon insulator is made by reinforce fiberglass, so the strength is higher common porcelain insulator.
Good resistance to soiling and flashover, since composite insulator have hydrophobic properties, the water also Formation of water droplets on the surface when rain, so the flash voltage is very high.
Good resistance to corrosion, since the raw material is silicone rubber so it have good resistance to corrosion.
High efficiency operation. Composite insulator have a good self-clean of storm, it don’t product zero value insulator so it has high efficiency operation.
Lightening weight, composite insulator have a big advantage than glass or porcelain insulator so it is easier when installation it.
Excellent pollution performance
Although there are many silicon insulator advantages, but it also have some disadvantages need to improve.
Disadvantages:
The price of composite insulator is higher than porcelain insulator
Since the raw material is silicone rubber so composite insulator have soft surface, so the sealing performance is easy to break when tough objects, result in decrease of insulation properties
