You must be familiar with the epoxy board. Xiaobian shared with you a lot about the characteristics and uses of epoxy panels. In fact, the epoxy rod and the epoxy board are basically the same, just like the same. It is also an important part of electrical insulation parts, and has great strength in the field of electrical components.
The epoxy rod, as the name suggests, is not difficult to find its shape from its name. It is an electric non-alkali glass fiber cloth immersed in epoxy resin, baked, molded by hot pressing after processing into a circular or square cross-section of the bar. Suitable for mechanical, electrical and electronic parts with high insulation structure.
The epoxy plate is generally divided into two kinds: one is the epoxy glass fiber bar, which is commonly known as the drawing rod, which is generally used as the main technical index of the lightning arrester or the insulator core rod. It has high mechanical properties and dielectric properties. The heat resistance grade is B. It has high mechanical performance at medium temperature and stable electrical performance at high temperature.
Appearance of the epoxy bar: the surface should be smooth and smooth, without bubbles, grease and impurities, allowing uneven colors, scratches, and slight unfairness.
