Primary and secondary polarity marks H1 and X1 are molded into
Construction and Insulation
The core and coil are enclosed in a case molded with GE Valox
thermoplastic polyester resin. This 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
flatwasher, one lockwasher and a regular nut. Because the
transformer is used primarily in enclosed switchgear
energized, a secondary shorting device and terminal cover are
not provided.

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. An optional
mounting bracket kit (part number 0021B00185) is available.
This kit must be ordered separatley if required.
Maintenance
These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is
severe.
