Pre-insulated Bushing Has Good Insulation Performance

Material Selection and Structural Design

pre insulated sleeve utilizes high-quality polymer materials, formulated with strict proportions, resulting in a clear inner and outer layer structure that enhances overall dielectric strength and voltage withstand characteristics.

Precision Machining and Surface Treatment

pre insulated junction sleeve incorporates multi-layered shielding and anti-seepage isolation sections in its structural design. The surface treatment process is meticulous, resulting in a high degree of surface smoothness. Through precision machining, the internal air gaps and solid insulation layers work in perfect harmony, leading to a more uniform electric field distribution.

Strict Production Control

The production process is rigorously controlled. From raw material inspection to molding and curing, every step employs online quality tracking. Equipment parameters and temperature and pressure conditions are monitored to ensure the stability of insulated joint sleeve upon leaving the factory.
