Pragati Enterprises

• Three phase
• Self-healing technology
• Naturally air cooled or forced cooling

• Applications such as motors, transformers, induction furnaces, welding and lighting installations consume both reactive and active power, resulting in reduced availability and lower quality of power. This translates into lower capacity utilization and eventually additional capital and running costs.
• ABB with its cutting-edge technologies and extensive experience has developed a wide range of advanced Low Voltage (LV) capacitors, which offer simple and cost effective solution to improve power quality and reduce costs.

Product Design:

• ABB’s low voltage QCap-L series capacitors consist of a number of wound elements and a dielectric made of metallized polypropylene film. These dry windings are provided with over pressure disconnector for safety. The capacitor elements are treated in vacuum to ensure optimal electrical characteristics. Each winding is encapsulated in thermo-setting resin to obtain a perfectly sealed element.
• The QCap-L series LV Capacitors are available in cylindrical & box type models.

Product Key Benefits:

• Dry type design - The QCap-L series capacitor has a dry type dielectric which minimizes risk of leakage and environmental pollution
• Very low losses - Dielectric losses within the QCap-L series capacitors are very low and total losses including discharge resistors are less than 0.5 W/ kvar
• High reliability - The use of robust terminals minimize the risk of damage during installation and reduce maintenance requirements
• Accredited with International standards- The QCap-L series low voltage capacitors are IS: 13340/41 and IEC 60831- 1&2 compliant

Construction:

• Dielectric: Polypropylene film
• Dry PU resin; non-PCB (1 to 4 kvar) in normal duty
• Soft PU resin; non-PCB (5 kvar up to 25 kvar in normal duty)

As per the needs and requirements of our clients, we are involved in providing Low tension Capacitor.

• Reliability: customers can easily become victims of poor quality capacitors made with non-capacitor grade-film. ABB strict selection of raw material and its first class capacitor film ensure QCap a high reliability.
• Quality: ABB low losses design decreases capacitor temperature and increases the lifetime. The optimized thermal dissipation will prevent the premature failure which is not uncommon with many low quality capacitors.
• Safety: at the end of its lifetime the capacitor must disconnect itself safely. The ABB designed overpressure disconnection device guarantees a safe disconnection.
• Consistency: a constant quality over the time is most often a challenge for manufacturers. It‘s the reason why ABB is testing 100% of the products with criteria surpassing international standards.

The QCap is the cylindrical power factor correction capacitor
based on ABB‘s latest technologies and developments. This is
the result of more than a century of knowhow on electrical engineering and 70 years expertise on capacitor technologies.

Requirements To Make A Good Capacitor:

To make a good capacitor is not so easy as it seems. ABB, as
one of the pioneers manufacturing the first metalized Power Factor correction (PFC) capacitor, believes in seven requirements
to make a good capacitor.

ABB’s PFC know-how lies in several decades of accumulated
expertise and experiences.

QCap‘s top class performances are not only guaranteed by ABB‘s
technology innovation but also ensured by mastering the manufacturing process

• Best performances of the capacitors thanks to ABB top class polypropylene film
• Stringent and unique tests procedures
• Products 100% tested with criteria surpassing international standards
• Quality controls from raw material inspection to finished products packing.
• Continuous improvement of the manufacturing process.

Top Class Raw Material:

• Polypropylene (PP) film is the primary raw material to make dry capacitors. Its quality is one of determining factors for a dry capacitor reliability and lifetime.
• There are thousands of different PP grades in the market. Even the capacitor grade films vary in properties like impurities, consistent thickness and thermal behavior.
• ABB has vast R&D experience in PP film with more than four decades of dedication in this field.
• The ABB PPMZ (Zinc metalized PP film) guarantees top capacitor quality and long lifespan.

Abb Low Losses Design Means Higher Reliability And Longer
Lifetime:

The following features have been included in the capacitor design in order to reduce the losses to a minimal level:

• Top class capacitor grade film
• Optimized ABB metallization profile to minimize the electrodes losses generation
