减少在零件存货和费用：真空开关或接触器的被简化的设计有50%较少部份比等效空气磁性设备。

Reduction in parts Inventories and Costs: the simplified design of the vacuum circuit breaker or contactor has up to 50% less parts than the equivalent air magnetic equipment.

如今已有一批工程师们开始着手研发这样的一款设备—没有机械运动部件的磁性存储器。

And a group of them have now taken a step towards developing such a piece of kit-a magnetic memory with no moving mechanical parts.

被减少的维护：在设备的延长的生活期间，真空式样翻新可能减少维护尽量60%根据一项最近研究比较真空与空气磁性15 - kv破碎机。

Reduced maintenance: Over the extended life of the equipment, vacuum retrofits can reduce maintenance by as much as 60% according to a recent study comparing vacuum to air magnetic 15-kv breakers.
