Product overview
Meidensha’s regional switchgear operation publishes a dead-tank circuit-breaker design using dry-air insulation and vacuum interruption. This LearnSwitchgear record is intentionally limited to the 38 kV variant.
Verified configuration
The official page identifies 38 kV, 72.5 kV and 145 kV classes. Because the reviewed source does not unambiguously provide continuous current and interrupting duty for the selected 38 kV configuration, those structured fields remain blank.
Engineering significance
The design applies vacuum interruption and fluorinated-gas-free dry-air insulation to outdoor dead-tank apparatus, extending the technology discussion beyond conventional metal-enclosed MV panels.
Specification caution
Confirm system voltage, BIL, continuous and interrupting current, operating sequence, mechanism, seismic and environmental ratings, standards and regional service coverage directly from the current 38 kV technical schedule.
