World-- Real World Applications

& Generators
A
typical locomotive traction motor when stalled can reach
a temperature of 400°C to 500°C in just a short
period of time. High performance motors, generators and
transformers are often integrated into systems that must
operate under extremely harsh conditions. Yet used within
these devices, APICAL Polyimide easily endures this heat
without loss of mechanical or dielectric strength.
Where
mica or glass were once the only material available, APICAL
Polyimide can be wrapped thinner and tighter in motor
windings allowing thicker, higher current carrying conductors
to be used. You'll also find APICAL Polyimide in aircraft
engines, mining equipment and in the utility and petroleum
industries. Typical applications include armature coil
insulation, rotor and stator slot liner insulation and
magnet and thermocouple wire insulation.
The
critical properties of APICAL Polyimide that make it ideal
as a motor and generator insulation include its broad
temperature cycling range (-270°C to 400°C), it's
superior dielectric properties (dielectric strength of
7,800v/mil), its outstanding mechanical durability, coupled
with its high thermal index (240°C-Electrical) and
good chemical resistance.
