CAST series are Duelunds no hold barred capacitor
range. They are built with a conductive foil separated
by a paper in oil with the addition of a proprietary
WPIO dielectricum which necessitates several days
of impregnation under high pressure. This creates
a form with incredible damping properties giving a
mechanical stability hitherto unheard of. On top of
this casting process, a ring of hard-pressed paper
strengthens the damping properties of the design helping
music flow effortlessly.
These are the new CAST series, made at the newly revamped
Duelund Factory. Now fully equipped with the Jensen
winding and impregnation machines. The papers separating
the copper foils are vacuum impregnated in a deep
vacuum 100 times lower, than what was possible at
the old factory.
lead out, closest to the edge of the capacitor, is
connected to the outer foil and as such should be
connected to the lowest impedance path to ground.
