Company overview
Meidensha is a Japanese electrical-equipment manufacturer with power-transmission and distribution products that include vacuum switching technology. Its regional operation in the Americas publishes dry-air dead-tank vacuum circuit-breaker information for several voltage classes.
Why LearnSwitchgear tracks Meidensha
The 38 kV dry-air dead-tank vacuum circuit breaker extends fluorinated-gas-free insulation and vacuum interruption beyond typical metal-enclosed distribution switchgear. This makes the product relevant to the boundary between medium-voltage switchgear and substation-class apparatus.
Editorial scope
LearnSwitchgear creates a dedicated 38 kV record and does not combine the 72.5 kV and 145 kV variants into one set of assumed ratings. Continuous current, interrupting duty, certification and market availability remain unstated until the exact official configuration source is verified.
