Description
Isolating switches (disconnectors) are one of
high voltage switch appliances that are widely used. Its function
is to isolate or disconnect an electric circuit. Isolating switches
are largely used in power plants and transformer substations, so
its high working reliability is required. Because of no arc
extinguish chamber in isolating switch it is used only to isolate
or disconnect the electric circuit with no load current, keeping an
obvious isolating point between the equipment to be rehabilitated
and power supply so that safety of workers can be absolutely
ensured. Rated voltage of Isolating switch generally is 1KV and
over.
H.V.
isolating switches are classified as indoor one and outdoor one.
The H.V. indoor isolating switch GN series of products includes
following types:
GN2,GN6,GN8,GN****2(C),GN****2(CD),GN****2D,GN****0.5CD,
GN****2(D), GN****2(D), GN**2, GNF****2/**0A, etc. The H.V. outdoor
isolating switch GW series of products include types as listed
below: GW1, GW4, (H) GW***5,*6,**0KV, GW8, GW*3,
GWâ–¡**2(*0.5)/*****0, etc.
