General Details
Silicon rubber insulator is also recognized as composite insulator or polymeric insulator. One of its significant part,fiber glass rod, as it’s name, is made of fiber glass material and used as supporting core of silicon rubber insulator.  The fiber glass rod consists of dozens of fiber glass threads which makes it enable to bear high tension load in vertical direction. This is also why fiber glass rod is selected as supporting core of composite insulators, especially on tension type insulators and suspension insulators on electrical overhead lines.

The rod of polymeric insulator has very good performance on mechanical tensile property, while its cantilever load performance is not so optimizing as the tensile property. Even though in certain projects we use polymer insulator post type in power substation, its bending load and deflection have some problem compared with traditional ceramic post insulator.

Technical Info
The fiber glass rod can be made into different length and diameter to fit different demand of insulator.

For common silicon rubber insulator of 11,33kV, diameter of rod of insulator can be 16mm, 18mm or more. While for power substation and transmission line, diameter of fiber glass rod shall be bigger to enable bigger mechanical breaking load.
