Pre-insulated Bushing Structure Characteristics And Design
pre insulated sleeve is typically a single-piece molded casing, using high-performance insulating materials and precision-machined into a complete shell. This design provides stable dimensional accuracy and uniform insulation thickness, offering a reliable foundation for subsequent electrical connections. The single-piece molding structure reduces assembly steps, avoids potential gaps from multi-piece splicing, and improves overall physical consistency.
Material Selection and Molding Process
-
Material Stability: pre insulated junction sleeve uses high-temperature and corrosion-resistant engineering plastics, maintaining its original electrical properties under various environmental conditions.
-
Mold Machining Accuracy: The single-piece molding process maintains strict tolerances for the inner and outer diameters of the sleeve, ensuring a perfect fit for the connector insertion.
-
Shrinkage and Stress Control: During molding, the cooling rate and mold temperature distribution are controlled to effectively reduce internal stress and dimensional deviations.
-
Surface Treatment: Smooth surface treatment reduces friction, improves assembly efficiency, and ensures stable electrical contact during long-term use.
Features of Single-Piece Molding Design
insulated joint sleeve is typically a single-piece molded product, and its overall design affects the performance of the sleeve during assembly. An integral structure can maintain a uniform wall thickness and reduce the probability of local insulation weaknesses.
