General Information
The power capacitors produced by
FRANKE GMKP were specially designed
for reactive power compensation. Using
state of the art technology and
high-quality materials have enabled us to
develop a range of capacitors to meet the
demands of the future. Furthermore
FRANKE GMKP’s products and system of
manufacturing and service is part of the
new environmental protection industry
and will strongly work further to improve
our world’s conditions.
GMKP type name
FRANKE GMKP’s registered type name
worldwide based on FRANK GMKP’s own
special German technology.
FRANKE GMKP prime advantages are:
• completely dry capacitor construction, so there are no possibility of out flow
• special one form capacitor cane, also minimize possibilities for leaks
• no PCB using • filled with protective gas • fireproofing • overpressure and over-current tear off
fuse • self healing polypropylene foil • stable fixed connection • long life working Construction features For capacitors long life properly working
the construction and manufacturing
process has high priority and is constantly
observed by FRANKE GMKP’s specialists.
All GMKP power capacitors have cylindrical extruded aluminium housing with a special three cascade sealing method for the capacitor cane to provide leaks. Another FRANKE GMKP’s special is the double safety system, which not only protect in case of overpressure, but also switch the capacitor off in case of over-current.
The purpose is to protect the capacitor
against excessive pressure increase
inside. The inner connections are
separated for this purpose from the main
supply.
The internal construction includes
lengthwise separate windings of high
quality, resistant, metalized polypropylene
films. For example, a three phase
capacitor has therefore three windings.
The quality of the polypropylene film is
significantly responsible for the
self-healing ability of the capacitors and so
our special metallization procedure
ensures a high degree of capacitor
self-healing.
Our capacitors are delivered with the
appropriate discharge resistors. FRANKE
GMKP’s special design is the internal
resistors. In case of high power
consumption we so avoid arcs outside the
capacitor to protect the equipment from
burning and over-heating. Another
advance of this design is to reduce the
time for discharging in addition with very
low resistor losses and at least safe space
for installing the capacitor.
Application
Power transmission stations. Individual solution for fixed power factor correction (e.g. Motor, transformers, lighting etc.)
Group fixed power factor correction (several equipment connected in a group)
All kind of capacitor banks. Harmonic trap applications (e.g. oven, UPS, frequency drives and converters etc.)
Special application such as filter, DC transmission, etc.

Special Internal fuse with the weak point design -more exactitude and orientation
- Exactitude cutting time
The fuse will be cut off only on the position of the weak point of the fuse
-Fig.1,when the voltage of the units close to its maximum amplitude, that is, at zone current, in this case, it is power stored in the capacitance of the parallel elements which best guarantees a current sufficient to rupture the internal fuse
-Fig.2, when the voltage of the units close to the zone, that is, at zone to maximum current, in this case, it is line current circulating in the capacitor assembly which ensures breaking of the internal fuse.
