4. Indoor Power Zn85 40.5kv High Voltage Vacuum Circuit Breaker Advantages
5. Indoor Power Zn85 40.5kv High Voltage Vacuum Circuit Breaker Iec56 Structure Introduction
Circuit breaker at upper and composite insulation structure, effectively reducing the size of the circuit breaker. The main part of the circuit breaker (ie leading electrical circuit section) using closed structure, the main circuit components are mounted on a tubular insulating tube, insulation tube using an epoxy resin APG process from casting, so it is particularly anti-creepage.
This design greatly reduces dust accumulation in the surface of the interrupter, not only to prevent a vacuum interrupter receive the impact of external factors, but also to ensure that even under severe hot and humid and dirty environment, but also on the effect of showing a high voltage impedance state.
