Supply ZW8-12 / 630-20 high voltage vacuum circuit breaker, ZW8
outdoor vacuum switch
ZW8 series switch features
1. according to user needs can be installed 50 / 5,100 / 5,200 /
5,400 / 5,630 / 5 current
transformer external insulation using high-voltage silicone rubber
sleeve for composite
insulation! .
2. built-in multi-tap current transformer can be used as
over-current protection . !
3.The double-winding current transformer can be used for protection
and measurement.
If the voltage transformer, auto-reclosing controller and
auto-sectioning controller are installed,
the distribution protection automation and the functions of remote
measurement, remote signal,
remote control and remote adjustment of "four remote" can be
realized . . !
4.can be installed isolation switch . !
