SQUARECAP ® AC CAPACITORS - [ WINDING ]
The metalized polypropylene
film (MPP) is manufactured in house on machines of the
latest technology. It consists of two sheets of
polypropylene film, each with a thin layer of silver-
zinc-aluminum alloy on one side. Heavy edge construction of
the films provides better bonding between the electrode and
the metal spray area to increase current carrying
capability. It also ensures better resistance to the
electromechanical stress that occurs in switching surges.
The windings themselves are centered inside the can and
sealed with polyurethane resin. In this way ionization and
corona discharge are eliminated, resulting in capacitors of
highly stable characteristics and long useful life.
SQUARECAP ® AC CAPACITORS -
[ HIGH TEMPERATURE CAPABILITY ]
The low dissipation of MPP
film combined with the superior thermal conducting
properties of polyurethane permits operation at temperatures
up to 80°C hot spot temperature.
SQUARECAP ® AC CAPACITORS -
[ INDUCTOR COILS ]
For ratings of 6 kvar and
higher, each single-phase capacitor is provided with an
inductor coil (mounted between the offset terminal and
capacitor terminal) to control inrush current to the
capacitor, particularly for parallel switching and automatic
control applications. This feature ensures long term
stability of the kvar output and extended life.
SQUARECAP ® AC CAPACITORS -
[ DISCHARGE RESISTOR ]
All modules are provided
with resistors to discharge the modules according to IEC
requirements to voltages below 75V with in 3 min (IEC 83 )-
J) As a safety precaution, all capacitor terminals must be
short circuited before handling them.
PHASECAP ® AC CAPACITORS -
[ TRIPLE SAFETY SYSTEM ]
Self-healing technology,
overpressure disconnector and polyurethane impregnation
technology contribute to reliable and safe PFC capacitor
products. |
