Description
HWT’s Film/Foil capacitors oer an energy ecient polypropylene lm
dielectric. This heavy duty conventional lm dielectric system is designed to
handle unusual overvoltages and overcurrents without reducing capacitor
life. The Film/Foil dielectric results in low watts per kVAR power consumption
during capacitor operation. The less than 0.2 watts per kVAR losses and
corresponding low internal heat generation mean low operating temperatures
for the Film/Foil capacitor, a signicant factor in extending capacitor life. Film/
Foil designs feature time-proven Dielektrol, a biodegradable NFPA Class IIIB
dielectric uid. This design oers high reliability and long life and is suitable for
operation over a temperature range of -40°C to +46°C.
Line Terminals
Solderless connectors are provided on each phase:
Fuses
Protection is provided by 50,000 ampere interrupting capacity current limiting
fuses. A pop-up button on the fuse gives visual indication of a blown fuse.
Mounting
HWT equipments are designed to be mounted upright on any level surface.
