Advantage:
SZ9-M, SZ11-M voltage-regulation with load hermetically sealed
transformer is an energy saving product developed on the basis of
S9-M and S11-M, which has the same performance parameter as S9-M
and S11-M, and has good short circuit resistance and safe and reliable
service. It is especially applicable to places where there is large range
of voltage fluctuations. The voltage can be regulated automatically or
manually while the transformer is energized (with load).
Features:
1) The load tap changer is produced by Shanghai Saili Electric Material &
Equipment Manufacturing Co., Ltd.
2) The standard load tap changer has taps for ±4 x 2.5%
(9 steps 2.5% each). It can be designed with different steps according
to customer's demand
3) The voltage regulation can be 10% more or less due to the load tap
changer. It can be controlled in the distance and operated automatically
or manually while the transformer is energized (with load)
