LV Capacitor QCap

LV Capacitor QCap

The ABB cylindrical capacitor

Power Quality is a major concern to all size of business, be it industrial or commercial. It impacts energy usage costs, pollution levels and CO2 emissions, equipment failure, malfunctioning and lifetime reduction but also maintenance costs.

The ABB QCap will help to improve the Power Quality of low voltage installations by addressing poor power factor issues.

abb

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 know how on electrical engineering and 70 years expertise on capacitor technologies.

ABB QCap capacitor answers customer needs

Reliability: customers can easily become victims of poor quality capacitors made with non-capacitor gradefilm. ABB strict selection of raw material and its first class capacitor film ensure QCap a high reliability

Quality: ABB low losses design decreases capacitor tempera- ture 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 over pressure 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.

Safety

Safety is definitely one of the most important topic for a capacitor. The customer has to be sure that in case of issues the damage will be limited.

Over pressure disconnection

ABB safety concept and mechanism guarantee a prompt and reliable breaking of all three wires under faulty conditions. This concept consists of three parts:

Airtight: the state-of-the-art beaming and seaming technology and equipment ensure a perfectly hermetic cylinder.

Lock: the ABB unique design on a locking device to contain the three elements tight under both normal and faulty conditions.

Snap: with the airtight and the lock as prerequisites, the snap will break three wires promptly and completely.
