Who said it has to look like a surge capacitor? They look different, and as a matter of fact, they are. Surge protection capacitors are designed to protect high voltage motors and transformers from events with high transient overvoltages (e.g. lightning or switching surges). Keeping with our tradition of completely dry products, we have designed the first MV Surge Capacitor in self-healing technology: DSCTM In combination with the PD-free layout, the self-healing dielectric provides for extremely long operating life and highest operational safety. Unlike traditional oil-filled ALLFILM-capacitors which are bound to fail as soon as overvoltage or other stress factors have provoked a dielectric breakdown, the self-healing dielectric of DSCTM insulates the breakdown spot immediately and continues operation as usual.

The winding elements in our MKP(D) capacitors are surrounded by poison-free vegetable oil. Like our premium ranges of MKPg and MKP, the MKP(D) combines the best possible technical features with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our MKP(D) capacitors distinguish themselves by high AC-voltage load capacity and suitability for high rms and surge currents. Our MKP(D) are available as single and three-phase capacitors and well-suited for all conventional applications in power factor correction. They have a self-healing dielectric and are provided with an irreversible overpressure disconnector (break-action mechanism, " BAM "). Connection is made through convenient standard 6.3mm tab connectors. Technical layout, testing and application accord to IEC60831, UL810 and CSA 22.2.

With our long year know how and first-class production facilities, we are manufacturing capacitors in two basic technologies: MKP and MKPg™. In MKP capacitors, the winding elements are surrounded by poison-free vegetable oil, in MKPg™, capacitors, they are immersed by neutral insulation gas. When designing our product ranges, we focussed on the best possible technical features combined with eco-friendliness and operational safety, using special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. Besides excellent ratio of capacitance to volume, our power capacitors distinguish themselves by high AC-voltage load capacity and outstanding suitability for high rms and surge currents. Unlike some of our competitors who proudly quote fantasy ratings, we have really tested our capacitors to their rated values, allowing for sufficient reserves and guaranteeing flawless operation within the specifications.

The custom-tailored capacitors of our E70 series are mainly applied for power factor correction or as resonance capacitors in induction furnaces that are operated at mains frequency (50/60Hz). The E70 are made alternatively in two designs: Inside the steel case, there is a large number of individual self-healing capacitors, each one of them protected by its own break-action mechanism. In the event of a failure, the affected element is disconnected separately while the capacitor as a whole continues to function with slightly decreased total capacitance. Windings assembled inside a hermetically sealed metal case, filled with solid resin, and protected by a pressure sensor similar to the capacitors of our ranges E56/E59.

The capacitors of our SR17™ series were developed especially for the maintenance of older traction converters manufactured in the 1970s?1990s. By consequent development of our well-proven MKP-technologies, we managed to place self-healing DC-capacitors with very high energy density and stability of capacitance into can dimensions smaller than, or identical to, those of the traditional MP-capacitors (SIEMENS/EPCOS codes B25353), which makes them ideal drop-in replacements for maintenance and retrofit programmes. Moreover, the low-loss polypropylene dielectric permits a far higher AC ripple load than with the conventional MP-capacitors. Our SR17™ are housed in a hermetical stainless steel cylinder. As opposed to the oil-filled MP-models, these are filled with an eco-friendly solid resin which does not only make them safe against leakage of liquids but also insensitive to the shocks and vibrations common in traction applications. The same applies to their robust plastic insulators.

Using selected low-loss, self-healing polypropylene films and sophisticated manufacturing techniques such as high-vacuum drying and special coating patterns, the best of ELECTRONICON™s design expertise and highest care in manufacturing have been spent to prepare these capacitors for your most demanding applications, and toughest ambient conditions. Our long-life MKP UHDTM contain three delta-switched capacitor elements of short height and large diameter. The optimized combination of winding length, film size, and winding geometry substantially reduces inherent power losses and allows us to achieve highest surge and rms current ratings as well as an overvoltage strength and switching stability which before would have been known only of impregnated paper capacitors. An MKP UHD™ handles up to 250% of its rated current and current surges of 400 x IN. The permitted operating temperatures range from -40°C up to 70°C maximum temperature (average over 24 hours: 60°C).
