摘要

The method involves firstly dipping of a vacuum switching chamber (1) in a mucilage and afterwards inserting into a mold. The casting compound is then cast under corresponding process temperature and is cast into the mold. The casting compound selected is epoxy resin, which is cast at 170[deg]C. An independent claim is also included for a medium or high voltage vacuum circuit breaker.
