Requirements For Raw Materials Of Sealed Poles

The APG process has higher technical requirements for epoxy resin mixtures than vacuum casting materials, namely, stability at room temperature, high reactivity at high temperature, rapid gelation, short curing cycle, good crack resistance and impact resistance, and high resistance to mechanical and electrical stress. The internal structure of the sealed pole is relatively complex and the insert is large, which makes the product have high requirements for the material's crack resistance. Since the product molding process will be affected by uncertain factors such as the external environment, the material is required to have good process performance and a wide range of application to reduce the impact of uncertain factors such as temperature and humidity.
