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.

POLB HD 2-50 kvar HEAVY DUTY CAPACITORS

Heavy Duty (HD series) capacitors are designed to offer long time expectancy and outstanding performance with its higher electrical characteristics.
They are self-healing capacitors with low losses metallized polypropylene dielectric, filled in with inert gas N2 mainly or with resin.
They have an overpressure disconnection system which provide a high level of safety against internal defects cutting the 3 phases. Capacitors in cylindrical
aluminium cans, provided with a M12 stud for fixing and earthling. Connection is made by a terminal block with clamp type terminals.
The name plate includes a QR code associated to the individual test certificate and which offering us a product anticopy protection.
