Electrical silicone rubber insulator has become more and more popular in the world, because the world have a large need of electrics, so they have a high demand to meet, and traditional insulator like porcelain insulator, glass insulator can't satisfied people, so the electrical silicone rubber insulator are required.

silicone rubber insulators

Three parts of silicone rubber insulator:

Reinforce fiber glass
Silicone rubber housing and shed
Fitting on both end

Electrical silicone rubber insulator has many different structures, it can be divides into many types, such as, suspension insulator,  line post insulator, post insulator, cross arm insulator, and both of them are common types.

The advantages of Electrical silicone rubber insulator:

Good mechanical properties, since it 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 has 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
