FZW-12/630A Outdoor AC High Voltage Vacuum Load SwitchDetailed product description：

The FZW-12/630A outdoor AC high-voltage vacuum load switch is developed based on national standards such as GB3804.1-90 "3-63kV AC high-voltage load switch" and GB1985-89 "AC high-voltage isolating switch and grounding switch", absorbing the characteristics of similar foreign products and combining with China's national conditions, under the guidance of industry experts. This product can disconnect rated current, close short-circuit current, and has obvious disconnection points, load disconnection, and very reliable power isolation performance. It can be equipped with a manual mechanism or an electric mechanism (the electric mechanism also has manual function), which can be operated locally or remotely.

2、 Usage conditions of FZW-12/630A outdoor AC high-voltage vacuum load switch
1. Altitude not exceeding 1000m;
2. Surrounding air temperature: upper limit+40 degrees, lower limit -40 degrees
3. Wind pressure not exceeding 700Pa
4. Earthquake intensity not exceeding 8 degrees
5. Ice thickness not exceeding 4mm
6. Not suitable for places with flammable, explosive, chemical corrosion, and severe vibration
7. Pollution level of post insulators: ordinary type is level 0, and pollution resistant type is required according to requirements

3、 Main characteristics of switches
1. The structure of the switch is to add a vacuum arc extinguishing device on the basis of the isolation switch, so it not only has the function of a load switch, but also has the function of an isolation switch.
2. The speed of opening and closing the switch during the process is ensured by the fast mechanism in the arc extinguishing device, so the opening and closing are
The speed is not affected by manual or electric motor operation speed.
3. The overall structure of the switch is simple, and the key arc extinguishing device is an integral structure that is easy to replace.
4. Can be operated frequently with almost no maintenance.
5. It can be electric, manual, near control, remote control, and wireless remote control.
