Capacitors for Lighting & Motors
Capacitors are used in industrial motors, especially
in variable frequency drives, to provide maximum
efficiency. The AC plastic film capacitors used in
industrial motors can handle thousands of volts per
cell, but at extremely low capacitance, generally in
the 1 microfarad range.
Capacitors are used in lighting to smooth signals,
suppress interference and in some instances provide
burst power. They can be either plastic film, ceramic,
or aluminum, and often use a combination of all
three dielectrics in a single ballast.
The materials used to protect these capacitors must
ensure safety and reliability, and must be in compliance
with mandatory requirements such as UL.
Our materials are characterized by:
· Very good processability
· Low viscosity for good penetration
· Low moisture uptake
· High adhesion to the plastic or aluminum housing
for perfect sealing
