Why Is Epoxy Resin An Ideal Choice For Insulators?
Publish Time: Author: Site Editor Visit: 8
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.
