What Are the Applications for V.P.I.
V.P.I. has a real advantage for
users who require longer machine life and increased reliability
where particularity harsh environmental conditions can arise
in applications such as mining chemical, marine and food industries.
V.P.I. can increase tolerance to marginal overloading of machines
because of better heat transfer and elimination of hot spots,
enabling heat to be dispersed through the structure of the machine.
Is V.P.I. New?
No vacuum pressure impregnation,
using conventional varnishes, has been around almost as long
as the electric motor itself.
What Will V.P.I. Do?
V.P.I. systems are suitable
for the treatment of new machines, rewound machinery, right through
the range of electrical machines from fractional horsepower up
to the limits imposed by capacity and tank size.
They are suitable on all machine voltages up to 11k.v. Providing
that the coils are manufactured with a conventional insulation
system for this voltage. They are suitable for stators, rotors,
armature, field frames and field coils.
A single V.P.I. treatment is equivalent to two or three varnish
dipping and bake cycles.
