WST、WDT系列無勵磁分接開關(條型)
WST、WDT Series de-energized Tap-changer ( Bar form )

本開關適用于頻率50、60Hz，設備最高電壓12、24、40.5kV, 額定電流20-300A的三相、單相油浸式電力變壓器，其調壓部位有中部和中性點兩種，可直接固定在變壓器箱蓋或箱壁處，在無勵磁狀態(tài)下分接調換。
This tap-changer is suitable for three-phase or single -phase oil-immersed power transformer with frequency 50，60Hz. Highest voltage for equipment 12、24、40.5kV, rated current from 20 to 300A，it can be equipped directly on transformer tank cover or tank wall, they must be working under non-energized condition。

型號后帶Z為金屬座(加強型)
The end of model with Z is metal seat (reinforced)
反向在原型號后加F，例: WST II 63/40.5-6x 5F
The reverse,at the end of the original model add F ,for example:WST II 63/40.5-6x5F
