Graaff Van Generator Price And Quantity
Product Description
Graaff Van Generator
- Very large and very spectacular apparatus
- Sparks up to 100 mm
- Spheres diameters 260 mm and 100 mm
- The Van de Graaff vertical generator comprises a silicone belt that acts as a conveyor for electric charges.
- Its movement is ensured by two cylindrical pulleys.
- One of them is in the hollow metallic sphere.
- The sphere is at the top of an insulating column which contains the belt.
- At the base of the device is a crank which actuates the driving pulley.
- On this type of generator, the larger the spherical envelope, the higher its potential.
- Theoretically, with a perfect surface for the metal sphere, the maximum voltage is of the order of 30 kV for each centimeter of radius.
- This theoretical value is not reached in practice because of different parameters: irregular surface, losses, etc.
Technical characteristics
- Dimensions:750 x 260 x 380 mm
