WINDCAP ® AC CAPACITORS -
[GENERAL]
The compact Windcap
capacitor is a self-healing, metalized poly-propylene film
capacitor using MKK technology with self-healing properties.
The current-carrying metal layer (electrode) is vapour-deposited
onto one side of the film.

COMPACT DESIGN - LOW HEIGHT, WEIGHT AND VOLUME ]
Three electrically
separated capacitor elements are wound concentrically in a
single operation onto an insulated metal core tube, which
guarantees excellent winding precision. The electrodes are
connected by metal spraying the face ends of the winding
elements. The capacitor elements are delta nested (also at
690 and 800 minimize losses.
The compact winding elements are housed in a cylindrical
aluminum case and hermetically sealed by a press-rolled
metal lid.
WINDCAP ® AC CAPACITORS - [
TRIPLE SAFETY SYSTEM ]
Dry technology: instead of
a liquid impregnating agent like oil or PCS, the capacitor
is filled with gas. So there is no risk of fire caused by
spurting or leaking oil. Dry design is a must for
ecologically sensitive applications and insurance follow-up.
Self-healing: the capacitor repairs itself after overload.
Overpressure disconnector: this prevents the capacitor from
bursting at the end of its useful life or through electrical
or thermal overload.

INNOVATIVE AND RELIABLE SIGUT ® CONNECTION TECHNOLOGY ]
SIGUT terminals ensure
reliable and straightforward connection, even in a parallel
capacitor circuit, with benefits like:
Simplified parallel connection of capacitors.
Protection against electric shock hazard (IP20 to VDE 0106
part 100).
Additional connection of discharge resistors for extra
reliability and safety.
Clamping device to prevent loosening of screws.
Cable cross-sections up to 16 mm˛.

HIGH RUSH CURRENT WITHSTAND CAPABILITY IS CRUCIAL ]
Capacitors used for power
factor correction undergo a lot of switching operations. The
high inrush currents that go along with this must be handled
without degrading useful life. The pulse strength of this
technology comes in particular from the enlarged, sensitive
contact area (improved metal spraying). The breakthrough
came with a Simens patent called the wavy cut plus heavy
edge film design. WindCap capacitors can easily handle
inrush currents of up to 300 times rated current.
WINDCAP ® AC CAPACITORS - [
AND WHERE IT IS CRUCIAL ]
Parallel connection of
capacitors.
Non-detuned capacitors.
Capacitor banks using standard contactors.
Restoration after voltage interruptions and brownouts.
WINDCAP ® AC CAPACITORS - [
EXTENDED USEFUL LIFE OF 130,000 OPERATING HOURS ]
After a long drying phase
in a high vacuum to eliminate moisture from the active
element the capacitor is impregnated. The case is filled
with inert gas and sealed. Then routine test are performed
for gas leakage.
This production process helps to avoid oxidation and partial
discharges (corona effect), promoting capacitance stability
over an extremely long period, an essential in filter
circuit applications.
