insulator core rod is made of epoxy resin and glass fiber main raw materials plus other additives through drawing, and has been widely used in China.
In China, it was developed for the continuous rise of the voltage level of composite insulators and the continuous progress of technology. The early ordinary rods were lacking in high temperature resistance. They had caused brittle fractures and other malignant accidents during the operation of the line. Therefore, with the accumulation of on-site applications, the production process of rods has been continuously improved, and new rods such as high temperature resistant rods and acid resistant high temperature rods have been developed. The main production process of the rod has gone through the following development stages: Different types of rods have been produced: ordinary rods-high temperature resistant rods-high temperature resistant and acid resistant rods-high temperature resistant and acid resistant transparent rods.
