JAD-AC Dimensions

Construction and Insulation

The core and coil assembly is encapsulated in resin within a
molded case. The case is molded with GE Valox thermo- plastic
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
winding, leads and terminals to form a waterproof unit.

Core and Coils

The core is made from high quality grain oriented silicon steel,
annealed under rigidly controlled factory conditions. The
secondary windings are evenly distributed around the core for
maximum accuracy and resistance to stray fields from adjacent
conductors.

Terminals

shorting device is provided and interlocked to the terminal cover.

sealing the cover.

Conduit Attachment

is available. It is suitable for outdoor applications. Box and cover
are made of aluminum with a black finish. The cover has a gasket
and four sealable thumbscrews. Two boxes are required for dual
ratio transformers.

Polarity

Primary and secondary marks H1 and X1 are molded into the case.

Primary Conductor

Removable primary bars are formed from 1/4” X 4” tin-plated, flat
copper bar, with 1/4” spacing between bars on multiple bar
assemblies. The bars are retained by insulated and ventilated end
caps, which permit the bars to be rotated to any desired
orientation and allow the transformer to be supported in a vertical
primary arrangement. A potential connector is provided adjacent
to one end cap. Primary bars are available in 11 7/8” and 14 1/4”
lengths, each provided with four bolt holes at each end.

Nameplates

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

Baseplate and Mounting

The transformer can be mounted in any position. An optional
baseplate is available, made of stainless steel plate. It is attached
to the transformer with two bolts.

Maintenance

cleaning if installed where air contamination is severe.
