Construction and Insulation
The core and coil are enclosed in a case molded
with GE Valox® thermoplastic polyester resin.
This tough material has excellent electrical and
mechanical properties over a wide temperature
range and is resistant to oil and a variety of
chemicals.
Core and Coils
The core is made from high quality grain oriented
silicon steel, annealed under rigidly controlled
factory conditions. The secondary winding is made
of heavy enameled copper wire. The secondary
windings are evenly distributed around the core for
maximum accuracy and resistance to stray fields
from adjacent conductors.
Terminals
Secondary terminals are No, 8-32 brass studs with
one flat washer and one lock-washer and a
regular nut. Because the transformer is used
primarily in enclosed switchgear compartments
which cannot be opened while the transformer is
energized, a secondary shorting device and
terminal cover are not provided.
Polarity
Primary and secondary polarity marks H1 and X1
are molded into the case.
Primary Conductor
A bus or insulated cable forms the primary
winding.
Nameplates
The nameplate is a polyester label attached to the
face of the transformer.
Mounting
The transformer can be mounted in any position.
Maintenance
These transformers require no maintenance, other
than occasional cleaning if installed where air
contamination is severe.
