Gn27-40.5 indoor high voltage disconnector is a new product. It is applicable to the power system with rated voltage of 40.5kV and AC 50Hz. It can be used to open and close the circuit under the condition of voltage and no load. It is a replacement product designed and produced to replace the old products. It can be fed with high-voltage switchgear and can also be used alone. Equipped with cs6-2 operating mechanism. All of them adopt reinforced insulation design, which can be used under the conditions of grade ‖ polluted places.
Technical parameters
Rated voltage: 40.5kV.
Rated current: 630A.
Rated short-time withstand current: 20kA (4s).
Rated peak withstand current: 50kA.
1min power frequency withstand voltage: 95kV (to the ground and between poles).
Lightning impulse withstand voltage: 185kV (to the ground and between poles).
Operating environment
Surrounding air temperature: upper limit +40ºC, lower limit -25ºC.
Altitude: ≤1000m (if the altitude increases, the rated insulation level will increase accordingly).
Earthquake intensity: not more than 8 degrees.
Water vapor pressure: daily average value is not more than 2.2×10^-3MPa, monthly average value is not more than 1.8×10^-3MPa.
Installation place: no fire, flammable and explosive, serious dirt, chemical corrosion and severe vibration place.
Operating mechanism
GN27 disconnector is usually equipped with CS6-2 manual operating mechanism.

In summary, the GN27 disconnector has the characteristics of scientific design, easy operation, and enhanced insulation. It is suitable for power systems in various complex environments and can effectively ensure the safe and stable operation of the power grid.
