The Influence Of Filler Ratio On Electrical Parameters Of Epoxy Resin Insulators
high voltage epoxy resin is widely used in power systems due to its excellent mechanical strength and electrical resistance. Their electrical performance is influenced not only by the resin itself but also by the type and proportion of internal fillers. By properly adjusting the packing material, the loss factor of high voltage standoff can be changed, thus providing a data basis for performance research.
The Influence of Filler Type on Loss Factor
Common fillers for epoxy resin insulators include silica fume, alumina, and glass fiber. The dielectric properties of different fillers directly affect the overall electrical performance of the resin.
-
Silica fume filler: Reduces dielectric loss and improves stability under high-frequency conditions.
-
Alumina filler: Improves the heat resistance of the resin and has a certain range for controlling the loss factor.
-
Glass fiber reinforcement: Improves mechanical strength, but an excessively high filler ratio may increase dielectric loss, requiring a balanced design.
During the selection and proportioning of fillers, factors such as particle size distribution and surface modification treatment significantly affect the loss factor of epoxy resin insulators.
