2、全密封（QMF）盘型、条型无励磁分接开关

全密封盘型、条型无励磁分接开关应用于全密封油浸式变压器，根据全密封变压器的要求，对开关的密封性能进行改进，采用双重密封，确保开关不渗油，从而提高变压器的整体水平。该开关与同型号普通开关的安装方法和安装尺寸是一样的。

Whole sealing（QMF）disc、strap non-load tap changer

The whole sealing disc、strap non-load tap changer is applicable to the whole sealing oil-immersed transformer and ameliorate the switch’s sealing property according to the requirements of the whole sealing transformer，meanwhile，it can improve the level of the transformer on all respects by adopting the dual sealing to ensure the non-immersion of the switch. This switch’s mounting dimensions and method are the same of the general switch with same specifications.
