A silicon rubber insulator is also recognized as a composite insulator or polymeric insulator. One of its significant parts, fiberglass rod, as its name, is made of fiberglass material and used as supporting core of silicon rubber insulator. The fiberglass rod consists of dozens of fiberglass threads which makes it enable to bear high tension load in the vertical direction. This is also why the fiberglass rod is selected as supporting the 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 the 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 problems compared with traditional ceramic post insulators.
The fiberglass rod can be made into different lengths and diameter to fit different demands of insulators.
For a common silicon rubber insulator of 11,33kV, the diameter of the rod of the insulator can be 16mm, 18mm or more. While for the power substation and transmission line, the diameter of the fiberglass rod shall be bigger to enable a bigger mechanical breaking load.
