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.
MFB COMPACT THREE-PHASE PRISMATIC CAPACITOR
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.
capacitors are especially suitable for the individual compensation of
inductive loads and the construction of capacitor banks.
