Descriptive Information
GEM III Series Construction
RBC 's Gem III capacitors are manufactured with
high-grade metallized polypropylene film. This film
is in the range of 6 to 10 microns thick, depending
on the application voltage and conditions. The
metallized electrode is several hundred angstroms
thick.
The film is wound into capacitor rolls on high-
speed, high-precision machines. The winding is
extremely tight so that there is not enough space
between the layers for corona (localized partial
electrical discharges) to occur. The rolls are
sprayed on both ends with metal to make
connection to the extremely thin edges of the
metalized electrodes.
The rolls are assembled in metal cases, RBC's
proprietary Dielektrol VI liquid is introduced under
vacuum, and the capacitors are sealed. They are
then subjected to 100% electrical testing for
capacitance, dissipation factor, and high potential
electrical withstand, both terminal-to-terminal and
terminal-to-case.
