Product Description
GN30-12 Type Rotary Indoor High Voltage Isolating Switch
Name: GN30-12 Type Rotary Indoor High Voltage Isolating Switch

Main application
GN30-12(D)type rotary indoor high-voltage isolating switch is a new type isolation switch of rotary knife type, the main structure is fixed two groups of insulator and contact on the two plane of plane of three-phase chassis, through the rotary contact, realize the switch on-off.
GN30-12
(D)type switch is a new type added grounding knife on the GN30-12 type switch basis, which can meet the needs of different power systems. The product design is with compact, small occupied space, strong insulating ability. easy installation and adjustment, its performance meets the GB1985-89AC high voltage isolating switch and the grounding switch "requirements, applicable to the rated voltage 10kV AC 50Hz and below indoor power system,to open and close the circuit when voltaged,no load. It can be used with the high voltage switch cabinet, and also can be used separately.
The use of environmental conditions
1. The altitude does not exceed 1000m;
2. Ambient air temperature:-10
ºC~+40ºC
3. Relative humidity; daily average value is not greater than 95%, monthly average value is not greater than 90%;
4. Contamination grades: no serious dust, corrosive and explosive material place;
5. Earthquake intensity: do not exceed 8 degree; No regular violent vibration place.
