GN27-40.5 INDOOR AC HIGH VOLTAGE DISCONNECTING SWITCH
Product Overview
GN27-40.5 indoor AC high-voltage disconnecting switch is a three- phase AC 50Hz high-voltage switchgear. It is used in a 35kV power system and is used to divide and combine circuits with voltage and no load. Equipped with CS6-2 manual operating mechanism or CX6 electric mechanism.
Working Environment
1.The altitude does not exceed 2000m;
2. Ambient air temperature: upper limit +40℃ , lower limit -25 ℃ ;
3. The relative humidity of the surrounding environment: the daily average value is not more than 95%, and the monthly average value is not more than 90%;
4. There is no place with fire, explosion hazard, severe pollution, chemical corrosion and severe vibration.
Product structure
1.The design is scientific, reasonable and novel in structure;
2. Multi-contact, rotary contact, good self-cleaning ability, improve heatdissipation ability
1.The contact points are in two surfaces, the operating force distance is small, the pressure resistance is large, and it is easy to adjust;
2.The use of creeping distance, strengthened insulation capacity, and withstand voltage meet the highest requirements.
3.Bearings are installed on the rotating shaft to increase the service life and easy operation.
