SF6 Gas-insulated LBS
RAF-12/630-20
Introduction
RAF-12/630 pole-mounted load switch is suitable for rated voltage 12kV, rated current 630A and 50/60Hz distribution system, and used for making and breaking disconnected, load current/overload current in the power system. It can automatically separate the fault section of distribution line when faults occur. The switch has manual, motor modes, it's easy and fast to install and the construction cost is low.
Ambient condition
Ambient temperature: Max: +70ºC, Min-25ºC.
Relative humidity: 100%
Altitude: <=3000m.
Wind pressure: <= 700 pa(equivalent to wind speed: 34m/s).
Seismic intensity: 8 degree.
Installation site : No danger of fire, explosion, chemical corrosion, frequently strenuous vibration.
Pollution grade : IV class.
Characteristics
SF6 is an insulation gas with excellent arc extinguishing performance;
Visible On/ OFF status, there are indicators on the operation side and the bottom of the device, it can be easily observed standing on the ground;
Durable, the switch shell is made of corrosion resistant material (304 stainless steel plate) and sprayed with protective paint to ensure a long service life (more than 30 years);
The main switch use fully sealed structure, not affected by the external environment;
Low leakage rate, less than 0.1%/year;
Mechanical stability of operating mechanism is high, mechanical life was designed as 10000 times;
All indicators use reflective materials, the state of witches can be accurately observed even in dark environment.
