GN19-12 High Indoor Voltage Isolation Switch with switcgear
equipment
The Indoor GN19-12 high voltage isolation switch use for CS6-1
human operators . Humidity is 95% .
It is mainly used for "isolation power supply, turndown operation,
for connecting and cutting off small current circuit", without arc
extinguishing function.
The isolation switch, usually referred to as the high voltage
isolation switch, is rated voltage above 1kV isolation switch, is
the most used high voltage switch electrical appliances, working
principle and structure is relatively simple, but because of the
high usage, high reliability requirements, the design, construction
and safe operation of power substation, power plant has a great
impact.
