Main Technical Parameters 采取多重折边工艺。这样使整个柜体不仅具有精度高、很强的
抗腐蚀与抗氧化作用，而且由于采用多重折边工艺，使柜体比 开关设备结构示意图

于采用了中置式形式，电缆室位置大大增加，因此设备可接多
路电缆。

Compartment
The main electrical components and devices used in the switchgear have their
independent compartments such as circuit breaker compartment,busbar
compartment,cable compartment and metering compartment.The degree of
protection between compartments is up to IP2X.To the exclusion of metering
compartment,three other compartments are provided with relief channels.
Connection of multiple cables in the bigger compartment space is resulted
from the truck's mid-position.
