Epoxy rod

1. Appearance characteristics
The epoxy rod is in the shape of a cylindrical rod with a smooth surface and flat end faces. There are many colors, including green, yellow, white, gray, etc., which are often used to distinguish different grades, batches or uses. The size range is wide, ranging from millimeters to more than a hundred millimeters in diameter, and the length is usually longer and can be customized according to customer requirements. Parts will be processed into forms with shed structures or threaded structures during application to facilitate connection with insulating jackets or metal accessories.

2. Core features
Epoxy rods have very high mechanical strength and can withstand large tensile, bending and compressive stresses. As a high-performance composite material, its fiber content exceeds 80%. Glass fiber is the main load-bearing phase, and epoxy resin plays a bonding and protective role. It has excellent electrical insulation properties and is an ideal insulation material, especially suitable for high-voltage power equipment. At the same time, epoxy rods have good thermal stability and can still maintain good mechanical properties at higher temperatures. It has excellent moisture resistance, low water absorption, and is not prone to performance degradation due to water absorption. In addition, it also has good corrosion resistance, and acid-resistant products are especially suitable for corrosive environments. Epoxy rods have high processing accuracy and strict dimensional tolerance control, making them suitable for precision assembly.

3. Main purpose
The main application of epoxy rods is in the power industry, as the internal support structure of composite insulators, to withstand mechanical loads and provide electrical insulation. It is also used as arrester core rods and fuse core rods, serving as insulating and supporting components in high-voltage fuses. In high-voltage switches, transformers, cable terminals, and other equipment, epoxy rods are used as insulating supports or structural members. In addition, they are also used in the aerospace field as lightweight and high-strength structural parts; acid-resistant products are suitable for corrosive environments in chemical equipment, such as pipes, brackets, etc.; they are used in rail transit for insulating components or structural supports; and in machinery manufacturing, they are used as insulated shafts, rods, support arms, etc. in precision equipment.
