[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
operator 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 nected (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.
[ 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 mm².
[ 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.
[ AND WHERE IT IS
CRUCIAL ]
Parallel connection of capacitors.
Non-detuned capacitors.
Capacitor banks using standard contactors.
Restoration after voltage interruptions and brownouts.
[ 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.
