Why Is Epoxy Resin An Ideal Choice For Insulators?

The axial tensile strength of the epoxy resin steel core rod used in high voltage standoff insulators is very high, generally above 600MPa, which is 5 to 10 times that of porcelain. The strength of high voltage epoxy is comparable to that of high-quality carbon steel. In addition, the specific gravity of the core rod material of epoxy resin insulator is only 2.0, which is much lighter than steel; the specific gravity of the shed material of high voltage epoxy resin is also less than 2.0.
