Embedded pole

The Technique, theory, and Structure of Xuguang Embedded Pole Embedded pole Is also called encapsulating vacuum interrupter. which encapsulates the vacuum interrupter and main circuit conductive terminals into an integrated part by casting resin. This design enables the VCB to operate under very abominable environment. The technology ot encapsulating vacuum interrupter is a great achievement on VCB insulation. As we see, the external insulation of VCB experiences Air, compound, and now solid. In the first generation when the external insulation medium was Air. the conductive parts were exposed to atmosphere, and therefore the external insulation level of the VCB got decreased because of collision during transportation, heavy humidity and condensed dust in operation In the second generation, vacuum interrupters were placed inside epoxy cylinder, while the conductive parts were still exposed to air This technology, however, did not eliminate the impact from the environment, such as dust, moisture, and even insects. The third generation is encapsulating vacuum interrupter and conductive parts Into an Integrated part through the process of Automatic Pressure Gelation, which not only makes the vacuum interrupter smaller, but also completely eliminates the impact of dust, moisture and insects from the environment; otherwise, as an integrated part, embedded pole is also an mechanical support, which has better advantages in electric field distribution and mechanical stress than board-insulated structure
