Analysis Of Pain Points Of Traditional Pre-insulated Bushings

Traditional pre insulated sleeve mostly uses PVC (polyvinyl chloride) or ordinary rubber, but in small household appliances, the pre insulated junction sleeve made of these materials exposes obvious shortcomings: insufficient temperature resistance (PVC is only 70°C), easy aging (easy to become brittle under long-term high temperature), and poor flexibility (insulated joint sleeve cannot adapt to frequent bending scenarios).
