Construction and Insulation

The core and coil assembly is encapsulated in resin within a
molded case. The case is molded with GE Valox thermoplastic
polyester resin. This tough material has excellent electrical and
mechanical properties over a wide temperature range, has low

The polyurethane resin filling completely encapsulates the

are molded in polyurethane resin and have slightly larger
dimensions.

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 tin plated brass, compression type with

A shorting device is provided and interlocked to the terminal
cover. The terminal cover is made of a clear plastic. Provision is
made for sealing the cover.

Polarity

Primary and secondary marks H1, H2 and X1, X2 are molded into
the case. In addition, H1 and X1 are identified by white dots. Cast
units designate H1 with a white polarity mark only.
Primary Conductor
These transformers are primarily intended for installation over

then forms the primary conductor.

Nameplates

The nameplate is laser engraved aluminum. It is attached to the
top of the unit and has provision for attaching the user’s
identifying tag. The nominal current rating is on both faces of the
unit in large numerals.

Mounting

The transformer can be mounted in any position but is usually
installed on the pad mount tranformer terminal blade using the
Valox “grabbers”. The grabbers are removable and the
transformer also has two mounting holes allowing it to be
attached to a mounting bracket.

Maintenance

These transformers require no maintenance, other than
occasional cleaning, if installed where air contamination is
severe.
