The GNF38-32KV series indoor isolation switch is designed and manufactured to meet the needs of the development of fixed high-voltage cabinets and ring main units towards compactness and miniaturization. It has a three station structure and a fully insulated bottom plate; And equipped with coaxial locking and a complete mechanical interlocking mechanism, the appearance is compact and small. It is the best optional switch for compact box type switchgear.



5、 Main structural characteristics of GNF38-32KV series indoor high-voltage isolation switch
Adopting the busbar through wall integral insulation bottom plate (APG process), the external insulation creepage distance can reach 24mm/kV, and the insulation performance is good.
The single break point and three station structure ensure that the isolation switch cannot be grounded when closed and cannot be closed when grounded.
Equipped with coaxial manual operation mechanism and position positioning device.

6、 Environmental conditions for the use of GNF38-32KV series indoor high-voltage isolating switches
a. Surrounding air temperature: upper limit+40 ℃ lower limit -25 ℃
b. Altitude below 2000m
c. Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%
d. The surrounding air should not be significantly polluted by corrosive or flammable gases, water vapor, etc
e. No frequent severe vibrations
