Pre-insulation Structure Design Of Epoxy Resin Sleeve

The pre-insulation structure of epoxy bushing manufacturer achieves a balanced electric field distribution through multi-layered material composites and process control. The outer layer typically uses a high-strength insulating shell, while the inner cavity is configured with a dielectric system adapted to different voltage levels. The use of composite materials and their design specifications help match the electric field distribution characteristics under rated conditions.

This pre-insulation structure involves not only the dielectric properties of the materials themselves but also careful planning of the internal geometry. Different voltage levels of epoxy bushing for transformer show significant differences in the geometric dimensions and spacing between the conductor and insulating materials, aiming to create a reasonable equipotential electric field distribution.
