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 IEC60831-1 and IEC60831-2 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.


FML (R460) REINFORCED PRISMATIC CAPACITOR

Reinforced capacitors (R460)
Reinforced capacitors are used when the harmonic distortion level, even if reduced, is enough to produce dangerous overloads in the capacitors that exceed the safety values allowed by the IEC standards. These capacitors are manufactured with a reinforced dielectric, which provides high durability under very adverse conditions and could work continuously at a maximum current of 1.7 In or overvoltage value 1,15 Un.

Protection filters
Protection filters are used, in supply networks having a high level of harmonic distortion, when the final objective is reactive power compensation at the fundamental frequency. Their purpose is to avoid that harmonic currents overload the capacitors by diverting them to the mains. Protection filters are made by connecting reactors in series with capacitors, in such a way that the tuning frequency of the whole unit is set at a value between the fundamental frequency and the frequency of the lowest present harmonic, which is usually the 5th order harmonic.

Harmonic filters
These filters are used when the main objective is to reduce the harmonic distortion in the supply system.

 

FML (R460) REINFORCED PRISMATIC CAPACITOR 5 ... 100 kvar

Self-healing capacitors with low losses metallized polypropylene dielectric without liquid impregnants. Mounted in rectangular sheet steel plate enclosure having discharge resistors connected to the terminals, which are protected by the cover. These capacitors are specially designed for a level of harmonics, which while low, is enought to produce overcurrents and overvoltages that exceed the maximum overload values allowed by the standards.
