This paper describes a newly developed 72/84‐kV dry air‐insulated dead tank vacuum circuit breaker (VCB). VCB technology, which is essential for SF 6 gas‐free equipment, has made advances in the fields of high‐voltage, large current interruption and environment‐conscious design. Light weight, decreased size, and reduced operating energy have been achieved by the new design. From the viewpoint of insulation, the characteristics of dry air, hybrid insulation structure, and insulation strength in vacuum were considered. Various performance verification tests in accordance with standards have been carried out and the reliability of the equipment has been verified. © 2011 Wiley Periodicals, Inc.
