main feature:
VJ24 vacuum circuit breaker is suitable for 20kV power system, adopts optimized modular spring operating mechanism, reasonable design, simple and reliable structure. The maintenance-free mechanism is realized, which is a new third-generation high-voltage vacuum circuit breaker. A mature process is used to fix the vacuum interrupter and the main conductive loop to ensure stable and reliable insulation of the conductive loop. The primary conductive main circuit uses a special structure and material, which greatly reduces the heat generation, meets the temperature rise requirements and reduces the power loss, and the reliability has been greatly improved.
