Power Capacitors

LIFASA capacitors are manufactured using the most advanced technologies, coming from an in depth knowledge of the manufacturing process and also from very strict laboratory and R+D tests. The enormous experience in installations, acquired over many years, allow us to incorporate in the new design the necessary characteristics to optimize the use of the product.
Capacitors are composed of capacitive elements wound from low loss polypropylene film. This dielectric is vacuum metallized, what gives it an excellent self-healing characteristic (MKP).
Elements are covered with a thermohardening resin of high dielectric properties and are not oil filled. Elements are connected to obtain the required reactive power and are mounted in steel cases. Void spaces between elements and the case are filled with a non-flammable, inert and non toxic material. Each element is individually protected.
This construction system avoids any risk of explosion of the capacitor and meets all the tests specified in the -1 and -2 standards.

Advantages
Capacitors are dry type and consequently ecologically safe: there is no possibility of impregnating liquid leakage.
Losses are specially reduced: lower than 0.05% (< 0.5 W/kvar).
Capacitors are a self-healing type: in case of a dielectric breakdown, due for example, to a transient over- voltage, the self-healing mechanism vaporizes the metallic electrode around the breakdown point, allowing the capacitor to go on working normally.
Their weight and volume are very low, allowing them to be installed every-where without problems.
Capacitors use strong terminals that guaratee a fast and safe connection.
Capacitors, cover with their different series, a wide range of power and voltages to satisfy the most varied requirements.

CAB series are formed by connecting a FML three-phase power factor correction capacitor to HRC fuses, contactor, fast discharge resistors and limiting inductances. Control can be done by an external signal through a terminal block or by an on/off switch included in the equipment.

These capacitors are specially designed for the individual compensation of transformers, hoisting motors equipments and motors with star/delta starter or electromagnetic brake.
