注:(1)电流为30A的分接开关适用于3~6mm的变压器箱盖

     (2)电流为63A的分接开关使用于5~8mm的变压器箱盖

     (3)电流为125A的分接开关使用于6~10mm的变压器箱盖

     (4)电流为250A的分接开关使用于8~12mm的变压器箱盖

(5)型号后加D为双密封结构开关(即变压器箱盖上、下各一个密封圈)

(6)我们可以根据顾客要求,制造箱盖下加高的分接开关

(1)The tap changer of 30A current applies to the tank cover thickness of 36mm

(2) The tap changer of 63A current applies to the tank cover thickness of 58mm

(3) The tap changer of 125A current applies to the tank cover thickness of 610mm

(4) The tap changer of 250A current applies to the tank cover thickness of 812mm

(5) Model No. with D stands for double-sealed structural switch (Means there is a sealing ring mounted on and under

 the tank cover)

(6) Height below tank cover can be adjusted according to request
