Designed for indoor service; especially designed for
installation over the secondary bushings of pad-
mounted transformers from 75 kVA to 3000 kVA. For
mounting and application information, including use at
higher voltages, and matching the current rating to the
pad transformer thermal capability, please refer to the
Applications Information section of catalog GEP-9186.

A high temperature version is available for use in locations with unusually high ambient temperatures.

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 water absorption and is
resistant to oil and a variety of chemicals. The
polyurethane resin filling completely encapsulates the
winding, leads and terminals to form a waterproof unit. A
Valox® cover is attached to the back of the unit to give a
neat finished appearance.
/
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.
/
Secondary terminals are tin-plated brass, compression type
with a 0.275” diameter cross-hole for wiring and a ¼-28
clamp screw. 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.

Primary and secondary polarity marks H1, H2 and
X1, X2 are molded into the case. In addition H1 and
X1 are identified by white dots.

These transformers are primarily intended for
installation over the bushing and terminal blade of
pad-mount transformers which then forms the
primary conductor.

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 marked on both faces of the unit in
large numerals using a polyester label.
/2
The transformer can be mounted in any position but is
usually installed on the pad-mount transformer 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.
/
.
These transformers require no maintenance, other
than occasional cleaning if installed where air
contamination is severe.
