High-voltage generator with two plastic discs
Diameter : 20 cm
Rotating in opposite direction, on which tinfoil sheets are deposited
Consist of two disks, two Leiden cans, crests, brushes, dischargers and support
Two sets of brushes collect the loads and store them in two condensers
The condenser electrodes are connected to two metal rods with an insulated handle, the distance between them can be varied

Two metal discs vertically attached to an insulated stand, with an electrode attached to the middle of the disc, the support allows the coaxial approach of the discs to a 0 distance between them
Plate spacing: 0 – 160 mm.
Possibility of plates adjustment between 0 and 20 mm
Material of plates: solid castings, stainless steel or corrosionresistant steel
Diameter of plates: 250 mm.
No burrs
